[@compucorder64]

He doesn't need it. The righteous indignation is lighting a fire under him :) Not that I disagree. Moving back and forth between pretty small Dynaudio BM6A mk.II and B&W 602s, it did seem like an octave or or two opened up underneath the music. And that was nice. But, tbh it really wasn't the bass that made a huge difference working on the B&W it was the lack of distortion in the midrange, and the accurate soundstage. But then, I'm thinking maybe that the compromised design of the smallbox speakers contributes a lot to the midrange. Even the old Rega Ela floorstanders (transmission line, I think?) had better midrange than most typical studio monitors I hear.

[@davidfuller581]

Okay, let's go through this. You are straight up wrong on a lot of things. 1. Of course an 8050 can produce 50hz, there is literal objective evidence that they can do so. 2. A 1/4 wavelength transmission line is not anywhere near the only way to use the back wave from the driver. 3. Ports and 1/4 wavelength TLs are not super different from one another in practice. The only difference is you can make ports work in small boxes and TLs don't. 4. The extra phase rotation from a bass reflex system vs a sealed design presents as a steeper LF roll-off. 1/4 TLs do this too. 5. Ports do not work on the same principle as a 1/4TL. 1/4TLs are physical delay lines. Ports are Helmholtz resonators. You don't need the maze for a port, just the right dimensions for a piece of pipe. 6. Hoffman's Iron Law comes into effect. Bass extension, SPL, cabinet size. Pick two at the expense of the third. You can make speakers extend low if they're small, they just will have little headroom. You can make small speakers loud, they just can't extend low. You can make speakers loud and low, but they're huge. 7. Passive Radiators work on the exact same principle as a reflex port. They are the same thing. 8. High excursion drivers and EQ are usually used in conjunction with one another, because a driver with high linear excursion can take a bunch of EQ to extend a sealed box's response. This is usually done with a specialized filter called a Linkwitz Transform. 9. Any active speaker worth a shit has protection limiters and sometimes an additional electronic HPF to keep the woofers from flopping about like they're in an open baffle. 10. High excursion drivers are not high distortion. Xmax means maximum _linear_ excursion. Yes, as excursion increases so does distortion, but a driver doing 10% of its xmax at a given SPL is going to be much lower distortion than one doing 50%. 11. 1/4TLs are prone to severe interference patterns in the octave or so above Fb, unless you have a massive box where you can effectively make it lossy above the tuning. But at that point, just use a port.

[@KimonoEtrange]

Spot-on.

[@frankklemm1471]

There is no lambda/4 rule for longitudinal pressure waves. For electromagnetic transverse waves, there is a lambda/2 for the propagation medium. But even there an antenna can be many orders of magnitude smaller than the wavelength, think of a LW radio receiver. 25x15x5 cm in size, receives 2000 m long waves. I have compact loudspeakers that are level-proof at 40 Hz, the longest side is 32 cm. Lambda/4 is over 200 cm at 40 Hz. I have listened to compact loudspeakers for a long time, which at 30 Hz longest side is 40 cm. Lambda/4 is over 290 cm at 30 Hz. There's something fishy about your assertion, both theory and practice are off by a ridiculous factor of 7. The size is only important for the levels, but f-3dB is not specified above, but the frequencies where you can generate unpleasant levels with low distortion. Flapping pants, rattling doors in the next room, scraping from the bathroom. The frequency response of active loudspeakers is set independently of the TS parameters, just as an indication of where there might be gaps in your knowledge.

[@gabbajon5654]

Funny that you mentioned the dunning Krueger effect then say that ports ruin the transient response then recommend speakers that work off of quarter wave resonance which have very similar problems plus phase cancelation above the tuning frequency. Dont get me wrong there's nothing wrong with transmission line but suggesting that ported designs are the devils work shows a lack of understanding. Realistically if you want rapid fast transient response you need sealed speakers but they suffer from efficiency and low end problems in sensibly sized enclosures (unless you horn load them but that comes with additional problems) The entirety of loudspeaker design is just making favorable tradeoffs and if someone works in a small studio making music that doesn't have anything besides the kick below 100 there's nothing wrong with a ported enclosure

[@haraldklingsporn4087]

You can bring back the efficiency easily when you put more sealed subs into the room... In my working room of my studio, i have 4 12 inch in 50 Ltr sealed box each, which go straight down to 20 Hz, with around 1% THD at 20 Hz at 86 dB SPL... In my listening room, i am planning 4 18 inch in 100 Ltr. sealed cabinets each, which go straight down to 20 Hz... easy...

Here’s a bit of reality… Just a dose of perspective. Professional Mastering engineers are not using small speakers from the Sweetwater Catalog… let’s get that out of the way. Recording engineers that also “do mastering work”, most certainly many are using smaller, bookshelf-type monitors… also, A huge percentage of truly professional and high profile recording engineers are using smaller monitors as well… why? How can this be? It doesn’t take a chart or hyperbolic exaggerations… It’s simple. The single most important component of your monitoring system is: You. If “accurate” monitoring was the factor that determined the quality/success of a recording… we can just toss 99.69% of all music ever recorded and released. Because NONE of the legendary studios (or engineers) that made the records we (still) regard as pinnacles of recorded music, used monitors that come close to matching the specs laid out here. Not suggesting the scientific data regarding linearity and response and performance is anything less than true… accurate. Just pointing out that accuracy is irrelevant. Not an opinion. It’s just there proven by history. It’s simple fact. This takes nothing away from the truth that you and I would potentially benefit from larger monitors… But it’s important to remember because the seed of doubt or insecurity planted in a mind about the gear one uses, is measurably more inhibiting than the gear itself. Don’t fall victim to this skewed, if well meaning line of thought. Put even more simply, IF you can’t use (any) bookshelf-sized monitor to create beloved, revered, “successful” recordings… why are there so many “pros” that CAN afford $120k monitors that don’t spend money on them, and rather use smaller monitors? Of course the answer is that accuracy is less important than the experience, taste and skill. Use what you have, what you can afford… don’t buy anything believing the gear will fix YOU. 3 sets of different types of monitors is more valuable than any one set. Accuracy is relative. Always.

[@anandboss7034]

But I think the point is not that you can't mix on small speakers. You can make a great mix on anything if you have a good understanding of the soundproofing, but the point is that it will be much easier to get a good mix with more accurate monitors. It's like, a colour blind artist could paint an amazing piece, but generally we accept that it's gonna be easier if you arent colour blind

[@SHUTUPANDRECORD]

@@anandboss7034 Using your colorblind artist as the example… You’ve taken for granted that the flaw in her vision, is only a “flaw” in your world. She’s going to paint what she sees… and her “perfect” is perfect. Your interpretation is not. I think the point of the video was to get views. As this video was technically geared toward mastering, it’s slightly more true that bigger is better, but even still… at all times, the brain attached to the ears is the single most important factor… and more guys and gals than you’d think use medium/modest sized monitoring with inarguably successful results.

[@anandboss7034]

@SHUTUPANDRECORD well yes of course none of the flaws will be visible to the color blind artist, but let's not act like her perception is the only one that matters. If you care enough about your music to the point that you want to mix it professionally, you're probably putting it out in some way for others to listen. If your just making stuff for your self only, putting this much effort into mixing is kinda pointless.

[@SHUTUPANDRECORD]

@ Man I’m not sure where in your life you picked up this mentality, and I am not being sarcastic or condescending. Listen: 1. Your first sentence again misses the glaring point: YOU declared what she paints as flawed. This is not reality. It is only flawed by YOUR viewpoint. Relating to music, if that artist has declared the painting perfect… and for our purposes, she is the mastering engineer in this scenario… her perception is the ONLY one that matters. To further illustrate in terms of music production, let’s call her “color blindness” Small Monitors. On her pair, and across all the testing she might do in a car, headphones, earbuds… whatever… she considers the mix finished and done to her satisfaction. Because you put it on bigger monitors and hear stuff YOU consider flaws is beyond irrelevant. Point two and possibly even more importantly: The idea that some art is more “real” or “important” than other is just foolish, and wrong. It’s this mentality… that there’s a difference between “real” work and I guess “amateur”, that is the enemy of the artist. Now, I understand you mean no offense to somebody making songs in a bedroom or living room, whatever.. but the damage is the same. The PLACE and MEANS you record need not have any effect on how “professional” it can be. Anyway, I’m just sad when I see somebody type stuff that conveys the idea there are two classes of artists. Or art. Again, I’m not trying to insult or be argumentative. Just addressing points you’ve made and enjoying the discussion.

[@LEEKING2005]

This is the most idiotic and anti physic things I heard in a while. The reason a small cone cannot produce very low frequency is due to only one reason, which is the diaphragm's mass and the volume of air ( in terms of meter cube ) they can push. All the long throw, port reflexes, bigger diameter cone and etc designs all for achieving the same purpose/mitigating the lack of it. Let start by things you said that are obviously false. 1st one's regarding the wave length of the 40hz (around 8.5 meters), it's less to do with the chamber but mostly to your room acoustic. The rules is the less it reflecting/richochet in term of a single full sine wave travel length, the less peak and null it will artificially create due to the principle of superposition. What it actually mean is if you have a room smaller than 8 meters, you should not go so low on your speakers' design. It is also worth to mention the power of low/subbass frequency are the one boucne the most due to the penetration and far greater travel distance so it's the most expensive in term of acoustic treatment. Ironically that's also the reason why they designed most studio moniter in such small size bookshelf, near field speakers form that only go down to about 70-80Hz. 2ndly, the things about the long port and speaker chamber are completely false. 1st of all, the high q roll off in the frequency response is due to the port reflexes design and completely irrelevent to the speaker chamber size. Basically what port reflex doing is to smartly increasing the air volume by utilizing the backward movement of the driver, hence make the lower frequency seemingly have higher volume (but with the drawback of quickly roll of after such designed frequency). 2ndly longer port channeling length mean it will bounce way much more in the chamber. If you have any knowledge in term of acoustic treatment you know it's great in term of absorbing the wave energy but not in term of accuracy. 3rdly as with law of physic, the more air you push, the bigger the push back force it will generate, cause air do have weight. So in term of design, it's always better to seperate the subwoofer part with woofer and tweeter, cause the bigger mass and power in subwoofer will generate significant vibration (if you want high volume of sub bass) and the unwanted vibration will drastically impact the accuracy of woofer and tweeter part. That is the reasons why 3-way or more speakers generally are exponentially way more expensive compared to two way speaker plus a sub-woofer (seperate sub system). Also it's the main reason why generally soundbar doesn't produce good bass or will suffer great inaccuracy if bass was too loud. 3rdly, how low a speaker can produce is related to the listening distance, and so is the interference of your room's acoustic characteristics. Ironically that's also why most studio monitor design at near-field listening level and most entertaining hifi design at atleast midfield level. Cause what entertainment speakers want was the feels of great echo and surrounding by all frequency (especially bass), while studio moniter generally want more accuracy, with the indirect sound generally not more than 1/3 of the direct sound for accuracy purposes, and definitely not overwhelming bass bouncing back and forth in the room that not only ruining the high, but sometimes also the mid. Also another aspect on bass accuracy is it's always a trade off between diaphragm mass and volume ( or listening distance ). Heavy diaphragm mass can produce much louder bass due to moving air consistantly, but will suffer drawback from control due to vibration, inertia and momentum increased. So in contrary to a 10 inch subwoofer, many studio monitor prefer to actually listening an 8 inch subwoofer at much closer distance. So no, it's not the bigger the better. In conclusion, you are definitely not an engineer and you clearly don't understand enough to talk about speakers. It's simply isn't the bigger the size or the more expensive the better ( or in this case more accurate ). It's really no shame if you have no knowledge in a particular field, but I'll suggest you stick to the general expert recommendation if you're not capable to understand such simple physics. Small speaker for small room, big speaker for big room, long rectangular room with medium to low sub-bass and etc.

This has got a lot of upvotes now (no idea why). But I will respond: intro: low frequency reproduction is NOT inextricably linked to the mass of the driver so you start out on a very poor footing. sensitivity could feasibly be higher with a lower mass but higher linear displacement. So no, this is wrong. 1. you are describing the challenges of room acoustics and not addressing anything I said in the video 2. you start off by vaguely saying "things about the long port"... etc... and I'm wrong. I don't know what you are actually attempting to object to in terms of my video. You go on to to say that ports have a steeper roll off which I agree with and so I don't know why you think this is a critique. Then you say the other drivers should be separated. This completely misunderstands TL design, but OK, you can separate them but again this is not critiquing anything I have said. 3. you say some stuff about the challenge of designing a good sounding room which I don't find particularly objectionable but again I don't know why you think its a critique of my video. You then say smaller diameter drivers sound better or are more accurate. Well this is NOT true. It depends on your goal. What is better suited to producing 25hz? An 8" driver or a 15" driver? It depends on the goal. If you are responding to my "bigger is better" statement, I was talking about cabinet size and not driver size. And I think that was obvious. conclusion: you just insulting me now with no basis for doing so and finish off by saying "Small speaker for small room, big speaker for big room" which is not a particularly good rule. I literally say I will discuss this myth in my next video at the end of this one. Low tier comment ending in disrespectful bullshit. Try harder.

Studio monitors aren't even powerful enough to create a full stereo image. The are guides so that you can make sure you can get your mix leveled. That BS about flat frequency is a marketing ploy when the fact is people don't even like listening to drab sounding music. I already tried to flatten out mixes so many times and was specifically told the mix/master was too dull to get on radio. These people need to stop lying to people. Then they say you can't have color but if you don't, the standardized level of amplitude for your mix simply isn't there. Things just sound mono and mic level through both channels instead of the stereo imaging being evident and you being at line level so that the elements of the mix are loud enough.

Subwoofers (plural!) can sound good when they’re dialed in right. In most low end studios they aren’t though, and end up sounding absolutely horrendous. You can’t simply throw a woofer under your desk and call it a day, it’s proper difficult to get them setup.

[@RegebroRepairs]

@@APMastering No, now you are completely wrong. Biamping is essential, because the elements will interact with each other, and the amp will get a complicated dynamic impedance that changes when the elements fight each other. Sure, if you get a really powerful amp it probably doesn't matter, but again, people don't have infinite money and infinite space. Unless you are paying an expert to build custom monitors for your giant studio, you have limitations. For any sort of budget monitors, they need to be biamped. Full stop.

I dislike the current popular narrative that if you have a small room you should just mix on headphones. I own a pair of slate vsx but i hate mixing on headphones and my mixes turn out far better with speakers despite my setup not being the most optimal.

well the thing is, its extremely hard, if not impossible, to get a great sound in a small room because the smaller the room, the more treatment you need to correct the increasingly large problems but then thicker insulation means you have less space in the room and if you optimally treat it, there's not enough room left to work in.

There's so much that a small speaker can do that a big speaker can't. Imaging for one. Any speakers with large baffles have pretty poor imaging due to smearing from the baffle. Also a small speaker is more suitable for a smallish room (which is the average home studio) often creating more bass than a large speaker which will either cancel its own bass out due to standing waves or the bass will be so overpowering that they will essentially be useless. ALSO! and importantly , Nearfield monitoring can only be done on smaller speakers which allow you to get closer up to hear more detail and have less room interference. You cant near field monitor on large speakers due to the time alignment of the large drivers which need the listener to be much further back. Small speakers are not a "scam". Most audiophiles still lust after the BBC LS35A monitor. The first true mini monitor which still competes with the top monitors of today,

[@Feelingawesome0]

@@APMastering the baffle is the front panel of the speaker. Surely you would know this if you are promoting yourself as a speaker expert? This is simple terminology. The baffles do not contain foam on any speaker including the ls35a. They are the panel that holds the drivers and they play a significant role as they resonate ie move to some extent with the drivers. THIS is why in smaller speakers you hear more of the drivers than the front baffles and hence less smearing, better soundstaging, imaging and also improved detail. And to state that ported designs are "crappy" is arrogant beyond belief. Some of the most incredible speakers in the world are ported. Acoustic suspension systems (sealed box) can have benefits due to minimizing internal reflections. But they also have there limitations. Hence why many of the most well regarded large studio monitors (and small ones) are not sealed.

Yo, AP! Would you consider making a video series on “the best of the worst” and break down some of the better reference monitor offerings under a few key price points (£1000, £2500 and £5000) and breakdown the design pros/cons and which rooms/setups they may suit etc? You challenge people’s thinking and (and beliefs!) at times, which can be uncomfortable for some, but it’s great for the community to have healthy thought provoking discussions. I liked what you did with the headphones content. Few people can justify spending thousands on headphones but any half serious engineer can afford a pair of Sennheiser 650s. Brilliant video. I think the community could benefit from a similar view to speakers for smaller production rooms, with budgets on the more restrictive end. It’s not hard to get advice on what to do if you have all the resources. The harder advice to provide is what to do on a budget, without the bias’s and marketing nonsense. 🇬🇧

[@frankklemm1471]

In terms of size (room volume), there are two physical rules: * Directional factor, i.e. how directionally can medium and low frequencies be radiated. * Depth of the frequency response/radiated sound power/efficiency/magnetic flux of the stator magnet But even these rules are not set in stone; they can be delayed with complex technical tricks, just as it was possible to expose 10 nm semiconductors at 193 nm, although the limit should have been 48 nm. Immersion, special photoresists, phase masks, multiple exposures. Public address systems are mainly so large because you want an efficiency of 10 to 30% rather than the usual 0.1 to 0.5% (@200 Hz) or 0.01 to 0.05% (@10 kHz) for hi-fi.

As a grey haired lab person, I take offense at the assumption that I would understand the mathematical complexities of moving bodies and soundwaves in 3-dimensional spacetime on the intersect of complex broad-spectrum stereophonic musical program material, and the associated resonance and harmonics. Go ask an AI, my calculator ran out of digits. That being said, there is no replacement for displacement, every room sounds different, there is no such thing as accurate reproduction, people are basically deaf, the sound you are making was never real in the first place, and the best listening position is 1/4 ƛ of the lowest frequency you want to be able to hear.

In a sealed room, a sealed speaker can play down to 0 Hz. Max SPL depends on the displaced volume and the room volume. The loudspeaker drops with -12dB/oct from its resonance frequency, the room has a pressure chamber effect of+12 dB/oct depending on the position of the listener. Pole placement turns this into a linear frequency response. If you want an extremely clean bass response, you should set aside your superstitions and familiarise yourself with the necessary installations, such as DBAs.

Same issue with TL speakers. It's tuned to a certain frequency, but whenever it's an other wavelenght going in, it's either delayed or coming before. Tested some TL speakers and sounded really bad. Ever heard of PuriFi or Kartesian on PR speakers ? Actually, for me, this is the best of both worlds. BR/Port have a sound at the tuning frequency which chuffles and it's aweful. For PR, unless you go close to the Fs, they actually sound really good without distortion, especially with the brands said before. And, BTW, better have higher distortion at Unisson/ good Harmonic Frequency, rather than a really low at, 3/5/7th Harminc Frequency. Low harmonic distortion doesn't mean anything unless you say which harmonic it's effecting.

[@APMastering]

well any time you have even harmonics you probably have some amount of odd harmonics too but I agree being more specific is usually better. But it's not only about the harmonic distortion but also time domain distortion. I'm not familiar with you brands you mentioned but IMHO a TL which is done in a small cabinet is doomed to sound terrible. There's no way you can call it a TL with a straight face when the line is less than something like 2m long and not well damped or with sufficient diameter. Even with glass fiber bats if the line is not sufficiently long, you will not have a TL but rather a shitty kind of port tuned to a weird frequency.

[@joseph.cotter]

Um, you're comment "sound isn't a sine wave..." I have no idea where you are coming from with that because it very much is. It is exactly that. A 'sine wave' is the specific form of an energy waveform a particular energy pattern, sound in this case, is composed of... so your statement makes no sense. Perhaps what you actually were thinking is that the waveform being shown in the marketing material wasn't showing the true picture as it is a simplified version of the true waveform, and also which (the marketing version of the waveform) doesn't show aspects of the sound wave that degrade it from what one would optimally want. That would be understandable.

[@CaptainProton1]

But music is not 'A' sound wave in the singular, of course as you know it is many thousands upon thousands of sine waves. But I guess he is saying that the tests are done with a single sine wave sweep at a set volume that gives the best result. a any louder and the test is out of spec same with quiter. Makes sense if true.

[@joseph.cotter]

@@CaptainProton1 First, he said "sound isn't a sound wave." That is just false. Second, these 'multiple waves' you are referring to get merged into a single wave when they are in the same space. Think of it this way, when you throw a pebble into a pond, it creates ripples, when you throw a second pebble into the pond, that creates a second ripple, however those ripples interact in a way that the surface of the pond has a single combined ripple pattern at any point of being sampled. There are differences if sampled from different points in space, however... in the case of an instrument that creates harmonics, etc... those harmonics are basically not generated from different localities and thus are overlayed on the wave pattern of the current time/locality. It is an additive/subtractive combination. That's why sound cancellation works. A better example might be this, think of what one would see if they put a microphone in the center of an orchestra and put an oscilloscope on the incoming signal. It would be a single waveform, not multiple waveforms for all of the instruments. that waveform is exactly an electrical signal that exactly represents the sound wave the microphone is picking up (excepting some minor differences due to physics in the microphone and wires that induce distortion into the incoming signal..) and that single wave contains all of the sonic information for all of the instruments playing at that moment.

Music is not inherently a bunch of sine waves. While it can be analyzed or broken down into sine waves mathematically, that’s not an accurate representation of what music truly is

@@FreemanHubbard Yes it actually is, on a physical basis. Take some physics classes.

Hello, the idea of building diy monitors is tempting. I was looking at wilmslow audio tl15, but it would be too complicated to import it to my country. I'm wondering what is your stance with the front wall SBIR considering how deep the speakers are? In my experience, the moment a speaker is deeper than 30-40cms, the front wall SBIR is becoming a problem if the front wall treatment is not deep enough to attack the frequency of interest, but paradoxaly if it is deep enough it pushes the face of the speaker further from the boundary pushing the fw SBIR frequency even lower. So, to make long question short, will you flush mount them or you have other means to battle the fw SBIR considering their depth? PS: All of this I asked has no meaning unless you have a giant room to put your speakers very far away from the front wall.

Since nearly all critical details of a mix occur between 500Hz and 8kHz this range, and in particularly the phase coherency of any system where the crossover point between mid and treble is in this range is absolutely critical 3) The downsides of large baffles in terms of diffraction, baffle step, soundstage 4) Sealed box monitors including those from for example present day productions MUM8 and MUM10 which use high excursion but very low distortion purifi drivers (widely regarded as some of the best woofers on the market) 5) Measurements of waterfall, phase & distortion and specs of your own speakers 6) Why not combining smaller monitors with a sub would be an option or judging the bass end using headphones would be another.

[@BrentLeVasseur]

Since most people don’t have ideal listening rooms with good treatment, the best speakers are ones that minimize the room interaction while maximizing resolvability. For active monitors in a small untreated room (which is not ideal), speakers like the Kii Three or Dutch & Dutch 8c monitors are best as they calibrate themselves to the room. For passive speakers, open baffle are best, as they minimize sidewall room reflections. Speakers like the Gr-Research NX Extremes or Spatial Audio X5 open baffle speakers can still sound amazing in normal relatively untreated rooms because of the nature of open baffle and how it minimizes sidewall reflections (you still have front and back-wall and floor and ceiling reflections, so it’s not perfect).

Frequency is time, not size.

[@Vossst]

Waves have a physical size. You can measure it. Hear about that trick where you can turn a grape into plasma in a microwave? Same deal. Reason bass traps sit away from the wall rather than on it? You bet. Reason bass instruments need to be larger, and treble instruments smaller? The waves are like hermit crabs, they want a home that's the right size for them. :)

[@gr500music6]

@@Vossst Thanks for the reply. Let me add that waves only exist over time, so seeing them as "distance" can be problematic in a world of time and space. Sure, their "length" matters, e.g.as pertains to calculating room modes and such. But a pair of headphones can reproduce 50 hertz and 10 kilohertz just fine for musical purposes - both tones generated at the same distance from the ear. The devil in the details is the word "per" in "per second." If we chose a longer distance from the sound source than the half inch inside the phones, say 1,130 feet at the beach, peak amplitude from the low A on a piano will arrive at our ear about 27 times per second and, from a tuning fork, about 440 times. If we move twice as close to the sound source, there's now only room to get half as many total pulses in a second. But pitch from the speaker down the beach won't drop an octave; it will remain the same. Either way, the 27.5 hertz wave will be about forty-one feet "long" and the tuning fork's about two and a half feet "long." But this doesn't matter for pitch. Multiply each "length" by the frequency and you'll get the same answer: 1,130 (because we got that number by division in the first place; that's the "per" part). I find it's helpful just to think of pressure peaks impinging on the eardrum per second. Cheers.

[@gr500music6]

Should have said "those numbers", not "that number." We took the distance and divided it by the frequency.

[@devon-graves-studio-D]

Notwithstanding the nonsense spouted in this video, frequency does in fact have a size relative to the time.

@@devon-graves-studio-D I know what you're saying but can't say I want to follow you there, Devon. Mainly for semantic reasons. Yes, the spacing of moving events, say spl peaks travelling at 1,130 fps in air can, of course, be expressed as a distance in feet. Personally, I still like frequency expressed in its pure meaning, which is how often something occurs over a stated time frame. The frequency of presidential elections, for instance, is three months per year but has no normal spatial element (I think. I suppose you could measure them as four trips round the sun each).

[@jrgroberts]

I can't add up how many errors there are in this. You don't seem to understand the concept of near field. I am inter alia an audio and mix engineer and have specified and constructed various studios, speakers, and other professional gear, some for other manufacturers. You completely mischaracterise how soundfields in small rooms work and ignore pressure response. Soundwaves are pressure waves not transverse waves. According to your nonsense, headphones could not reproduce bass. Yes of course big speakers can have better LF response. They are just better, but they are for the far field. Their main feature is however higher sound pressure levels. That's because they are not designed for the near field. In the far field much higher levels are required from the LS for the same SPL at the ear. The PSI monitors you pointed to are a ported labyrinth design. The entrained energy in a ported system is a function of the entrained volume, and so small ported speakers have less group delay than larger ones, on average. The problem of distortion due to high excursion is nowadays readily digitally rectified, and Philips fixed this via motional feedback in the 1970s. I suggest you stick to your areas of expertise. PS I don't like labyrinth designs, and if you think 12" speakers are sufficient for far-field bass, I have to disagree. PS2 try Wilmslow Audio for parts and materials. No connection, just a prior customer.

I am not aware of any manufacturer alleging that their small speakers produce more bass than their large ones. And you still fail to understand sound propagation in small spaces.

​@@APMastering The more i watch the video the more annoyed i am !!! What do you think you have with your "special" AP Mastering Speakers ? WHAT DO YOU THINK ?!?!? You built a Transmission Line Speaker, a speaker with a longer, folded resonance tube ( a tapered or maybe straight one ), tuned to ??? Hz !!! So.... it IS a port... an long one ! BELIEVE it or not ! Google it and make a "scientific" research about it, if you think, that is really better than a normal vented speaker... Shortcut... Transmission line have the worst bass behavior in Time ( Phase ) and Frequency ( Comb filtering like a organ pipe ). Another shortcut, cabinet order: 1. = the best choice ( Time / Phase / Frequency and Accuracy ) is Closed Box. 2. is passive radiators 3. vented box 4. is Transmission line Horns ans stuff like that are at point 4. When you don´t believe it... GOGGLE IT ! You maybe think closed box is easy to build. NO it is harder to build, when you want do it right ! Next.... So... only big speakers can reproduce 20Hz for example ?! Whats about Headphones ? With a 40 to 80mm membrane, without air between Membrane and ear ???? I know there is air between Membrane and ear, but way less than in a room... HOW can they reproduce 20 Hz, with such small membrane excursion vs. a 20 Hz Wavelength ? It´s a question for yourself, i don´t need a answer ! You mentioned the two 6 inch woofers in your special speakers ! Where is the difference between these speakers and a two way monitor with a 6 to 8 inch woofer, paired with a 12 inch Sub in a closed enclosure ( better 2 subs, one for each channel ) ????? WHAT IS THE DIFFERENCE between a Coax speaker system, a normal 3 way speaker and a Main / Sub combination ??? I tell you... Time and Phase ! Time and Phase is the point, why many people don´t like Subs, cause they sound boomy... YES... they sound boomy ! When Time and Phase is not correct adjusted !!! WHEN Time and Phase is correct, you can't hear whether a sub is playing the first octave or not !!! The Google tag for that is Step Response ! The Step Response gives an overview how the single speakers react to an impulse, over the time domain. So Tweeter comes first as the fastest speaker ( right on the initial impulse ), then the Midwoofer, more or less than the Tweeter ( depends on moving mass, RMS, and B/L ). Then........ a long time later, the subwoofer as the slowest speaker, cause of the upper woofer things. So and that is IMPORTANT, you need to delay the tweeter and the mid woofer, down to the slower Subwoofer... The Step Response is near the same for a 3way speaker like yours and a normal Main / Sub combination... Google it !... Of course the sub can be slower in time, when the sub stand 10m away from the mains, but that is not a problem today, especially not in a full active system ! You tried to slow down the tweeter against the 6 inch woofers, but you have forgotten the 12 inch Woofer ! DO you really think that your Transmission line Speaker has no Time, Phase or Step Response problems... REALLY ?!?!?!? And the worst thing about your video is... You mentioned the room with not one single word !!! So for me it is only a marketing video about your "special" speakers ! WHY ? Cause you did not mentioned Transmission line speakers in your video, especially not as a bad choice ;-) Back again... The room is the biggest problem ! Cause the sound of Speakers, will be damaged by the room ( room modes and early reflections ) down to around 60 % of the real potential of a good speaker... When you treat the room to a Tech3276 compliant room, for example, the accuracy rises up to over 90 % Btw. Early Reflections are the problem for the sound changes, when you move your head from left to right, out of the center position !!!! I have a Tech3276 compliant room, a smaller one with a RT60 middle time around 150ms. AND i have smaller speakers as Mains ( 6.5 woofers with a AMT Tweeters in a 11 Ltr. cabinet = size of a YAMAHA HS80M ) together with 4x 12 inch woofers in closed cabinets. And i can tell you that this system goes straight down 20 Hz... straight, no f3 !!! This system has a PERFECT Step Response over the complete system of 8 single drivers. A good Group Delay of under 10ms at 20 Hz ! A good Phase behavior and all that in a Reflection Free Zone ( RFZ ). Cause of that, i can move my head between the speakers and the sound is still the same. The 12 inch Subs btw. have only 50 Ltr inside each. The system is complete active. Each speaker driver ( the subs are paired ), have their own channel with Phase, Delay, Crossover, EQ and Amp... and only ONE DA conversion from the DAW to the speakers... Have i mentioned that the THD is around 1%, at 20 Hz and 86dB SPL, in a production ready room and i can hear between 50 dBA and 100 dBA without a significant loss of quality ? The overall weight of the rock solid system incl. amps is 340 kg and the amps have overall 3500 Watts ( Class AB, not the digital crap, 3000 Watts for the subs to easy control them with low THD, 280 Watts for the mids and 220 for the Tweeters ) !!! THAT is Mastering Grade, with costs less than 10K and under 13K with room treatment ! And no... i don´t sell anything, no blueprints, no BOM !

@@APMastering In medium-sized loudspeakers, bass reflex systems reduce the timing errors of sound that is essentially perceived with the ears. For very low frequencies they increase, but even in perfect rooms (or outdoors) the differences are not audible. I'm talking here about 8-inch woofers and bass reflex resonators tuned to 28 Hz. In the 40 to 50 Hz range, these are clearly better than closed enclosures. And that's where the music plays. The max SPL is also increased in this range. And especially in the high-end range, this range is hardly reproduced cleanly and crisply, but rather blown up. Negative list: * Sonus Faber Amati Homage * B&W 805 * Estelon AURA I like it balanced at 80 Hz to 200 Hz without the hi-fi hump, below 80 Hz it can go up very slightly. And then you should dampen the room properly.

Pretty cool speaker you made there, looks like the basic duntec design for midrange and a pmc style transmission line for the bass. Did you align the magnets for better time alignment? I enjoy the sound of the budget jbl 3 series monitors given the price, I think low end has always been a challenge to get right on those setups though. I mixed an electronic track on a pair of Kef ls50's once and was pretty blown away by the results, I personally don't think you can really get into a mastering grade monitor's until the Focal Be series. A cool low budget speaker that you can mix with pretty solid results is the Fostex PM03 or 04 because you can get your kick and bass level from the driver starting to distort like on NS-10s, not bad imaging either. Have also had decent results with the Slate digital headphones, not as fun as speakers but they solve a lot of issues in terms of mix translation and have pretty coherent low end.
