You CAN'T handle the TRUTH! with GR-Research

[@mattpu1]

I'm still using these behringers for my home theater surround sound speakers. I'm thinking about upgrading. Does anyone know how these behringers compare to the emotiva b1+? Would the emotivas be an upgrade?

[@darrenschmitz2712]

Ironically I am watching this video while opening up my box of upgraded crossover components from GR Research, this makes my 3rd set from them now. I completed the crossover upgrade GR did for the Insignia B2111s and its amazing how good these cheap speakers sound with this change. I literally can't go back to listening to speakers that used the typical cheap crossover components, for me there is a harshness to the highs that plague them all. Thank you Danny for these videos and for help!

[@inmyopinion6836]

I was listening through my laptop and a Klipsch sound bar . Not only did I hear the difference , I felt it in my nasal passages and my upper chest . WOW . This was a new effect for me . I NEED to go somewhere and listen to a class 1 system .

[@yuckysamson]

What is great about this is that like all other respectable speakers designers, Danny acknowledges that measurements are great tools and are to be respected and utilized in the design process, but then there are palpable, real differences that can be had by engineering choices and component changes that CANNOT be measured. In other words Danny uses both measurement tools AND his ears to identify elements that he feels improves or lessens loudspeaker performances. It's something that all "science-only" audiophiles need to get through their heads to understand system building and reality.

[@rhalfik]

I get your point, that people can get ignorant of actual listening experience, but I wouldn't go as far as saying, that these differences cannot be measured. If they're real, they can be measured. It might be difficult, unobvious or impractical to do so though. As the time goes by more and more is being estabilished. Currently most secrets of sound quality are discovered and the picture we get of it is clear enough to build acoustically transparent line level gear, where any further improvement of measured response isn't perceivable. Furthermore the problem with subjective tests on music material is that your impression depends on the program you selected. Someone else will listen to a different song and will pick up problems that you didn't hear. In an ideal world, where time wasn't limited you could have several people listen and then investigate their impressions to eliminate the problems. But that has already been done by Harman and many others, so nowadays you can just follow a measurement workflow with proper rigor and get good results. They'll maybe not please 100% you personally, but you'll get a thumbs up from the majority of users.

[@Brick100]

How do you suppose these "sonic improvements" are being engineered into the products if they CANNOT be measured? How does that work exactly?

[@rhalfik]

@@editorjuno Unfortunately yes. But if you changed just one thing there - replaced subjective input with double blind testing, than it'd sudenly be much more robust. A waste of time, but reliable one.

[@gino3286]

hi if i understand well he run only feq response measurements There are a lot of other measurements that can be carried out on loudspeakers I have concluded that a FR alone is not enough to characterize a speaker sound What about distortion instead ? better quality parts in the xover can result in lower distortion at the microphone The testing is very valuabe but should be developed further These are the words of a great speaker designer John Dunlavy " DAL firmly believes that a full set of credible measurements, made by qualified engineering staff using state-of-the-art equipment and facilities, can reliably predict the potential of a loudspeaker to accurately reproduce the complex sounds of music."-Dunlavy Audio Labs

If you can hear an obvious difference and you can't measure it then your ability to measure is the issue.

That’s true.

[@impuls60]

The upgraded version has a lot more precise end trails of notes and of micro details. I'm amazed at such a big difference.The effects gives the illusion of slightly more treble. I wonder if most of the improvements is mostly in the tweeter crossover?

The 2 coils have the same inductance but different resistance. Same with capacitors . These differences change the frequency responce (db-wise) of each driver in a different way (and the crossover points consequently ). Thanks for uploading!

[@dakken74]

So there not "EXACTLY" the same values just higher quality? If the higher quality parts had the same resistance as the cheap one would they sound more similar because the values are actually the same?

[@dannyrichie9743]

The air core inductors are larger gauge so there is little to no difference in resistance. And changes to the resistance of an inductor only effect amplitude in the range of 1/10th to 1/1/20th of a db below 200Hz or so. The values were also exactly the same. Caps were matched also. So no differences there either. Measurements of each are posted via link above.

[@rhalfik]

@@dannyrichie9743 But this is just FR. Where are other important measurements? HD? IMD from coils?

[@rhalfik]

@@dakken74 Dakken, higher quality part has different values, than a low quality part. That's the difference between them. It's just that a part has more properties than just one or two. The result can theoretically be viewed as harmonic distortion. ironically this mean that a difference - heared or not - can be measured.

[@dannyrichie9743]

Accurate distortion measurements can not be taken outside of an anechoic chamber. And they don't reveal anything about the audible differences. And I do have a full set of measurements on them.

Clear improvements even listening through the built-in speakers of of my iPad Pro (1st gen)!! Naturally much more defined through my full rig, but interesting that the improvements can be heard over such a humble device

[@gregorymorrill7558]

Honestly friend are you sure? The difference reported on real systems tend to be on the "this is subtle but, I can hear it and it is a better" trend. My hearing is pretty good - honestly, at first I heard a clear difference each time liking the second playback - which slowly faded into hmmm, maybe not as obvious as I played the tracks in different orders and jumped from speaker a-b-a-b-a-b at the same point in the song. I am not saying there is not a difference by the way. I am saying I highly doubt the ipad reveals it. Those things sound horrible to me.

[@siletteman]

gregory morrill OK, I confess! My iPad is not a standard one. It’s been upgraded internally with Sonicaps, , Erse inductors, Mills resistors, OFC wire etc. Of course, these components are bulky and therefore the rear aluminium panel has to be left off, but hey!, this just gives even better sound because the iPad is now running open baffle. ;)

[@kenkeim2487]

Amazing, even on my headphones I could hear the difference. I noticed it on the first track. At first I thought it was a different track, because I heard more chimes on test B. Overall, test A sounded blurred, while B sounded separated and defined. It was almost like Dannie’s crossover stopped the speaks from carrying the notes when they were supposed to end. Giving greater definition to the music. Clearly there is a big difference .

[@cliffordcostley9798]

Just two quick tech questions. When upgrading electronic components, it is often advised to maintain the same values but upgrade the quality. Does maintaining the values include the precision percentages? And why or why not?

[@herrtrigger7220]

no, if the precision percentage is the same then they are probably the same, if you are referring to their 'quality' not value.

[@grandpixel]

Honestly if there is truly such an obvious difference with upgraded crossover parts, then there has to be some metric by which it can be measured.

[@spacejaime]

No, those metrics do not yet exists, only frequency response for speakers and impedance loads.Try measuring treble grit, grain, tizz, bloated bass, dry midrange, etc. Try measuring transparency, sound-stage (width, depth and height) and imaging. Good luck measuring that. Only the ears can measure those metrics - in your brain. If you can't notice it, you can always buy the cheapest speakers you can find. Cheers!

[@grandpixel]

Jaime if you can hear it with your ears, I absolutely guarantee 💯 it can be measured. If there’s no way to measure it, then there’s no way to hear it either.

[@grandpixel]

Jaime And that’s not really debatable. You can come up with all kinds of adjectives to describe what you hear, but you’re just describing an aspect of the electrical, mechanics, acoustic, and wholly scientific and measurable aspects of sound.

what would you guess the stock crossover cost vs the upgrade? Big difference is sound quality.

[@MrSunnyday4u]

Well this convinced me. I have a pair of almost vintage B&W705's (first series) that I have been wondering if I should upgrade or not. I saw Troels Gravesen have done a similar job on some 800-series crossover - That made me wonder and started a thought process. I'm fairly ok with the sound of the 705's. I have experimentet with different positioning and feel they lack a bit of 3D and depth. I have a fairly decent amp (Electrocompaniet ECI2), that might contribute to the lack of high highs. in the end I want the speakers to open up in a similar way that the "truth" speakers did. I used to own a pair of 684 back in the late 90's and they had a great sound for that price, and was capable to deliver an open sound stage (even on a denon PMA1500R). I got the 705's speakers for a very good price and think the cost of upgrading crossover components should be justifiable. I went online and did a quick "mock up" of mundorf and Jantzen components based on the schematic I found online. However some of the values did not match excactly .. since I'm new do this, I'm wondering what is the pitfalls when sourcing similar higher quality components and value macthing ? what is the do's and don'ts to be aware of? I don't want to change the crossover in any other way other than using better quality components.

[@tjkadar]

I didn't like the way the sound clips were set up. So I did it my way. I opened two KZbin windows and queued up A and B to the same part of the song. In this way, I could quickly flip from A to B within seconds. Still wasn't happy. So I flipped my chair around backwards (listening on headphones) and had someone else flip from A to B. Kind of a blind test. I consistently picked B as being 'better.' The differences were subtle, but each time, over several iterations of the test, I chose B. Not scientific by any means, but I was able to differentiate between A and B every single time and I always chose B. For the casual listener, I don't think the difference was 'worth' it. But if you're 'critically' listening, it would be an upgrade worth considering.

[@dannyrichie9743]

The differences are considerably greater in real life. Then differences in sound stage deep, layering, and imaging become real apparent, verses the stock version sounding very flat. You just can't get that from the recorded clips.

The salesperson was adamant about how using *anything* but dedicated switchgear was complete folly, but never got around to giving a believable reason why. Your thoughts?

[@dr.anthonyforgione4253]

Even as this choice of music is pleasant, enjoyable; and offers refined subtlety, its ability to reveal the sonic differences between the speaker set ups is significantly limited. This is because this piece of music has virtually no bass frequency content, and a relatively low, range of frequency. I just think that this very good/great piece of music, is less suited for speaker sound evaluation because it is just so constricted as a palette. As one example among of course so many, I suggest songs or samples from the album: The Best of Fourplay, among other albums from the group Fourplay. Superb ... recording quality; but importantly, solid, deep bass from drums/bass guitar, all the waaay up to clear .. pristine .. metallic cymbals. The best general, testing music will have a full complement of sound in bass, midrange, and high-frequency, which are all accurately recorded. You can listen wholistically, or drill down onto any given instrument and listen to/for fidelity, speed, naturalness, tone, and more. This music, will show you what your speakers, (and system) can and cannot do; and it’s better for testing than soo much of what is being used, even at hifi shows. You can’t experience the acceleration/braking/ cornering or performance of a sports car, driving it 25 mph. on a residential street. Your system and speakers are your vehicle, the music is the street, the **test track**, or the **race track**. I say, select music that can actually reveal more sonic characteristics. (The post above is particularly applicable to floorstanding/tower speakers, but also to bookshelf speakers and your Behringers.) Cheers.

[@dannyrichie9743]

Actually these three tracks were selected as it made the differences very easy to discern. And deep bass and drum tracks don't show off the differences as well. They are also not reproduced well with the speakers that this is often listened to on.

[@dr.anthonyforgione4253]

Danny Richie I see your point, I think it’s a good one. But you didn’t just change out a single driver for example, you changed out the entire crossover network and wiring. This is a fundamental change that effects the entire signal itself, and hence both/all drivers. If for example, this change had little or even no detectable change in the bass let’s say, I would like to hear, how, it has no effect. You learn a tremendous amount when this happens, it forms and literally is, your qualitative understanding. You have to hear it, not be able ...to do this or that. Do you know what I mean by that? (I prefer this also because I often hear things in audio reproduction that others cannot- as bad as that sounds to say. = ) ) I only heard one sound sample so far, but if/when offering say 2-3 or more samples, I really think at least one of the offered samples, probably always, should be full and wide-range- in bass, mids, and highs. (And generally, I don’t mean tracks produced artificially or digitally-even though I like this music too; for testing I mean real drums-a full set, have or not have voice, bass and rhythm guitar- minimally amped and processed. Jazz is very good actually. Better than symphony/orchestra for critical listening because it can have a wider frequency range-in bass guitar and bass drums, and s/o has too many instruments grouped together which affects clarity (and everything). Haha Fourplay is ideal- CD/vinyl/full res. FLAC though. Check it out.) You’ll never understand any speaker at all, until you’ve heard this (full-wide range music) through it.

[@dannyrichie9743]

Yes, what was done changed everything to both drivers. And various types of music had been listened to on them. The real differences (audibly) are detail or resolution levels, imaging, sound stage layering, cleaner overall sound, less smearing, and smoother and more natural sounding vocals. So tracks were selected to allow hearing those things easier.

No one listening to the sound clips knew which was which until the end, yet differences are still noted. And even though I knew which was which in real time as we listened still took nothing away from the fact that they clearly sounded not only different, but better.

[@carlosoliveira-rc2xt]

It doesn't matter. Those that believe solely on double blind testing invariably resort to blaming something else when differences are heard. Everything in life doesn't have to be placebo tested. I know when I drink great whiskey, drink a great cup of coffee, eat fine cuisine, drive a fine automobile and hear great music through a superior system.

[@luke9822]

@@carlosoliveira-rc2xt of course it matters. That's a silly statement, Carlos. Would you want medication that was not tested with a placebo? If my experience was the opposite of yours, who are others to believe? What if there were a hundred of us and 50 felt one way and 50 felt another? This is how truth claims are made and probabilities are found.

Very intresting how that makes so huge difference and it does not even show on frequency response :o does it show up on any other measurements? Group delay ? Or something?

I'm always in search for the truth and more knowledge when it comes to Hifi. The more you know, the more money you can save by not spending stupid amounts on overpriced crap. I learn a little bit more, everytime i watch one of your videos.

[@seedood]

Wow. Even on crappy Apple earbuds, it’s unmistakable. B was definitely warmer and better. I hope Danny comes up with a new crossover kit for the Klipsch Cornwall IV’s.

[@gregorymorrill7558]

dude, no offense but listening to any of this thru apple earbuds tells you nothing. Those earbuds are not even close to flat, not even close at all. Totally pointless, but I digress...

[@Neil-Aspinall]

I have these speakers and on the whole I find them OK regardless of the up grade. In the end you have to get used to monitors and once you're used to them and their idiosyncrasy's you'll be fine.

[@friedmule5403]

LOL Had these speakers for some years, they never sounded as good as on your recording:-) Thay are fine for a beginner low budget studio, but you have to upgrade if you want to hear the material correctly. I did only hare the first 3 a/b samples and since you did chose to start over on each sample, it were hard to know how much the difference really was. Please next time try to let the music play as one long number, while switching between the speaker configurations. And lastly, maybe let people listen to the music, before you talk about what you think, to avoiding telling people what they are suppose to hear.

[@dannyrichie9743]

These were playing on a pretty top level system. So they may very well sound better than on anything else they've ever been used with. And the comparisons are easier when the material is repeated. And no one really mentioned what anyone was supposed to hear prior to the link to the sound clips.

[@friedmule5403]

@@dannyrichie9743 I am surprised that they have been on a audiophile system, they are designed for entry level near field. Behringer is a great brand for those who want to go into music production, but have a low budget. If you had a piece of music and did switch from one configuration to an other while being at the same moment, you can really here if a voice do change, while if you have to listen for maybe 15 seconds before arriving to the exact moment, you have already "forgotten" how it sounds. A non trained listener, do remember for extremely short time, tests have shown that a non trained person can remember the approximate sound in up to 5 seconds. If you watch your video, do you all talk about how you each experienced the change. And that info do the listener take with them to your amazing recording. By the way, I am impressed on how clear you all express how you think the sound were, it's not an easy task to describe a sound, but you manages it every time. :-)

[@dannyrichie9743]

Actually it is a lot easier to discern playing the same segment then repeating it. And for most audiophiles 15 seconds is no problem. And it is pretty easy to cut back and forth on the segments to replay the same shorter segments back to back. I wish everyone could have heard it live. There is so much more that the mics just don't pick up.

[@friedmule5403]

@@dannyrichie9743 No for you who work professinally every day, 15 seconds may be duable, but not for most. We are talking about hearing minute details in difference, not major. :-) Look I know that you are honestely trying to deliver some facts. My reaction is due to how many times I have seen audiophiles, mostly professionals, tricked to hear something that wasn't there. I have even my self, been helper at a event, meant to investigate how easy it were to trick highly renowned audiophiles. We did as almost every salesperson do: 1) Presenting some "facts" about a new product. 2) Tell them about what they are about to here, what they shall be focused on. 3) play some music 4) Stop the music and talk about anything for as long as possible, so no one have a chance of remembering the former sound. 5) Play the exact same music from the start again, with no change at all in the system 6) stop, remember people of what they should be focused on 7) Ask people and about 90% did here the difference, even some did tell it were as night and day. And yes, it was top magazine audiophiles who wrote for a living. :-)

[@dannyrichie9743]

That's a funny story, and I am not surprised. A lot of those guys are more creative writers than trained listeners.

[@OHMAudioChannel]

Even on my Klipsch Pro Media PC Speakers on an integrated sound card I could resolve the differences.

Good evening (Indian STD time). Let me know one thing whether I am right or wrong. Speakers of any wats sound better if they are fitted in a box made out of Best quality wood than in a box made of any other material ?

[@rustyshackleford6978]

Bhalchandra Lagu Actually, speakers are best sounding in quality MDF, not soft or hard woods (you don’t want woods that resonate). You can certainly apply a layer of wood veneer to the MDF to make them look nice.

[@512bb]

Material science & the implementation of materials are a complex subject. Don't get caught up in defending any one approach. You tend to see a lot of MDF because its inexpensive, heavy & easy to work with.

[@tokobjork]

You should have recorded some sound clips to us youtubers to hear...

[@dragankraljevski7872]

I was thinking of replacing my B&W 686 s1 witch i listen with a B&W 608 sub in my leaving room via a stereo receiver. But after getting to know Danny via his youtube videos i was willing to do an experiment :) My x-overs were simple 3 components. L air core inductor for the woofer which i left original and a sand cast resistor and poly cap witch i replaced for a mils resistor and a SONICAP gen1 capacitor. And let me tell you it is exactly as they describe it here. The top end opened up. More space between notes. The speaker became taller and wider. Clarity improved dramatically. That's what i heard immediately. Just so i was not fooling my self i called my brother and did a blind test A B between the upgraded speaker and the original. Same conclusion. For around 50$ worth of cpas and resistors i got my self new old speakers :). Also ordered the Klipsch pr-600m kit for my other system. Can't wait to do them as well.

[@dentman67]

(Please read my last post here after listening on my system)Funny, A sounded better on my phone. B sounded a bit harsh in the upper freq's. This was again through my phone so my findings mean nearly nothing. Looking forward to doing the A/B again through my Cantons.

[@dentman67]

Ok I just got to listen through my home system in a dedicated and acoustically treated room. I played the clip through the youtube app on my TV. Digital signal then goes to a Yamaha pre/pro to a 120 watt per ch Rotel amp to some Canton tower speakers. I heard the diffrence almost instantly. No, it's not night and day. However for critical listening on a decent system it's a very nice gain. Unlike on my phone I didnt the gains in the upper freq's. The gains were without doubt in the area of clarity and spatial presence. I would for sure pay for a gain in sound quality like this. Would I pay for gaines like this for people listening mostly to home theater, no. Nor would I say this is worthwhile for the casual listen who rarely sits and listens to music, but mostly listens as background entertainment.
