Clickbait? Yes! Still interesting and worth watching? Yes!

[@TechIngredients]

Thank you! What really is click bait? I believe it is the false promise of content that doesn't exist. You take the time to click into a video and discover, after taking even more time, that there's little of value. With so many other options, this is frustrating. However, because there ARE so many options for the potential viewer, quality content gets drowned out, lost under the weight of highly promoted channels and their hyperbole. We want to compete for your attention, but we want even more to to provide interesting and informative videos that make you want to come back and subscribe.

[@DonJohn87_YT]

@@TechIngredients I'm perfectly fine with clickbait of this sort. It's kind of borderline with this as your thumbnail says "world best... (for 115 dollars)". If you called it something like "amazing value speakers for 115 dollar" it wouldn't be clickbait, but it's also not an eye-catching title. Anyways, keep up the good work! ;)

[@DonJohn87_YT]

@CybpnK If you read it as "the world best speaker *FOR 115 dollars"* then it might be true, but if you read it as "the world best speakers" then it's far less likely and most definitely up for debate. Either way the concept is really interesting.

[@TekkGnostic]

@@DonJohn87_YT "World's Best DIY Speakers!" Obviously high-end manufactured speakers are going to be nicer and considered standard professional equipment. Might be missing a word but all the similarly titled videos on youtube are a joke compared to the amount of research and development put in to these videos (I think it's a justified title.) These are probably equivalent or better quality than a lot of media speakers you can get at a much higher price point. Plus the non-directional emission of sound is fairly unique without many similar products on the market.

[@JodBronson]

Change Tittle to: *World’s Shittiest Speakers!* = Happy Dumb KZbinrs! 😂😂😂😂😂

[@ragir]

Just finished making these and while I do agree the bass could use some help, they sound insanely good for what they are, this is crazy. I just came back up from the basement after over an hour of listening to my favourite tracks and discovering new stuff in them, sitting there with lights out and having a massive grin on my face, thanks!

[@TechIngredients]

You're welcome! Check out some of other videos. This isn't unique.

[@ragir]

@@TechIngredients Oh I have been watching your videos for years now, I wouldn't miss this condensed knowledge repository made with accuracy and practicality in mind - I was here when the smoke bombs were going off ^^

[@keithmarlowe5569]

My preliminary thought is a 2.1 amplifier, with a sub box. I'm in process with first speaker build, and the subwoofer is only 8 inches and flat to just shy of 1,000 Hz. I'm crossing over at 100 for my 2.1 build because the woofers go fairly low, but I may try crossing at 800 to see what happens. It's a Peerless by Tymphany from Parts Express.

[@ragir]

@@keithmarlowe5569 That's basically what I did, just got a fairly cheap 2.1 amp and an old woofer, now it's much better - it's a system that I use in the basement gym, so it's more than enough.

I like that you cover these projects thoroughly and spread the content over multiple bite sized videos. I much prefer this format over one watered down video from which we only see a final product. Such watered down videos are not useful to me. You provide us materials and techniques used, details of tests performed, what DIDN'T work and why, and a summary of the lessons learned. YOUR VIDEOS GIVE ME WHAT I WANT. This is my favorite "tech" channel.

[@vhg8638]

sometimes the watered down is good. Thats what i was expecting, then dissapointed the video was so long, and finally i ended up watching alll of it. I love this GEEEKY stuff tho

[@23lkjdfjsdlfj]

Fascinating! I had to try this so I did. At first I tried just the ceiling tile: the mid range seemed good but it misses the hi frequency range and was 'blah' on its own. I then added the pink foam insulation speaker in series and it sounds great! What I appreciate most is the whole room sound - but your ear knows where the source of the sound is just fine. This helps my surround system a lot. Previously I could never hear anything out of the left surround speaker. It was too directional (mid-range bookshelf speaker). Now that I'm using the ceiling tile / foam insulation speakers I can hear the left surround channel - the clip clop of horse hooves, engine noises, bullets hitting things, etc. I'm quite happy about it. Apparently you can purchase speaker fabric in many colors, and a couple of companies will print/dye any photo you have on that material - so you can have hanging artwork / photos too!

[@matthewlind3102]

Amazing idea on the hanging artwork!

[@danielvanderlinden642]

That was exactly my idea too that would be great

[@lolololo2__515]

Does acrylic paint , mess up the sound ?

[@Leaf_man]

@@lolololo2__515 he recommended using spray paint at more then 40 cm away so that the styrofoam wouldn’t melt in the first vid in this series, so that would work at least for the styrofoam. I have a feeling acrylic paint would mute the sound, as he mentions in the vid that you have to take off the shiny outer layer of the styrofoam or else it could hurt the sound.

[@Fullchaos40]

@@Leaf_man simple solution. Mount the panels behind art so the panels are free floating accents on the art.

[@stevekerr2893]

Fascinating analysis. As a physicist, I wondered how the resonance peaks of a single panel design might be minimized without combining it with other panels with mismatching peaks. So, I built a pair. Each speaker of my pair is 1" extruded polystyrene, but is cut to the dimensions of a golden rectangle. The height is 1.618 times the width (my panels are 25" high) and I rounded the corners. The exciter is placed at the first level or primary eye or focus of the golden rectangle. The idea is that the distance between the exciter and each pair of opposite sides is an irrational number. Theoretically, I thought, this should reduce resonance causing interference patterns. Finally, I used a nail set to form hundreds of cone-shaped holes in the material through the side edges of the panels thinking this would break up and reduce internal reflections from the edges, again reducing interference and resonance. I have no way of measuring the result, but the sound quality is extremely immersive and rich. Love to get your thoughts. Thanks.

[@denb7068]

Ah the Dunning Kruger effect.

[@gogauze]

​@@denb7068 I don't think this is necessarily a Dunning-Kruger thing-at least with respect to the videos. I can't speak for the commenter The part that's most well known about the phenomenon is that there's a significant correlation between folks with a small amount of knowledge, in some domain, and their confidence in what they truly know. If you look at the data from the original study, and many follow-ups with different experimental designs, it's clear that there are other variables that play big roles. The only notable effect, though, is that normalized comparisons typically only stretch or compress the same graph along the y-axis; the overall function is as close to identical as social sciences can really get when looking at those independent data sets. The main reason I bring this up is because, when the effect is in play, there's always an extreme drop off in confidence with moderate knowledge in the specified domain; followed by a more gradual rise in confidence as you approach high knowledge. I've personally become very cagey about speaking with authority on most things, not in small part because of this exact thing; the exceptions, of course, being the few domains that I'm both well educated in and well practiced-or, at least, current on the literature-with. If you couldn't tell already, my undergrad and graduate studies were all in psychology. I also practiced as a licensed therapist before disability smacked me down. It's the only reason I feel comfortable saying all of this with a straight face. Back to addressing the video with those insights on mind: I don't think he would have ever made this video, let alone said the thing, if he were strongly under the effect. He probably would have considered the first video authoritative, if that were the case. I think the quote is probably more akin to a colloquialism for "I am a human that makes errors, and here are those errors."

[@polly_D]

Never realized that there were sound transducers which could be attached to ceiling panels to act as speakers! Very interesting and thanks for all that research!

I was hoping that you would run a sound analysis of all four speakers playing together. It would be interesting to see what that graph looks like.

As well as simply sum the graphs and to see what that looks like.

[@kenlarock7356]

Seems the overall frequency response would be the most important test. The demo sounded a little light on the low end. Some digital processing would be appropriate, especially given the number of amps used to drive the panels.

[@MrTeff999]

@@kenlarock7356 There's no doubt in my mind that these speakers can't push a lot of air, so this system would need to be supplemented with a subwoofer. That said, whatever you heard was subject to the microphone he used, and the speakers you use.

[@eploidsam]

What do you hook the speakers up to? I wan to try this too, but I know very little about audio systems. Do they have to connect through an amplifier or could you connect them strait to something like a car stereo. I don't know what the 4-ohm 8-ohm thing is either...

[@reazhasan4953]

@@eploidsam Passive speakers such as these always have to be driven by a power amplifier. A power amplifier may be built into your car stereo but you'd have to ensure that the power output of the stereo amplifier is matched to the speakers or else your sound setup can be over or under-driven. Both scenarios have severe short comings. I'd encourage you to read a bit more about the topic before attempting to hook up speakers for fear that you might ruin your speakers or burn an amp or two. :) Ohm is a unit of resistance or passive impedance. So when a speaker is a 8 ohm speaker it presents a 8 ohm load to the amplifier. The lower the load, the easier it is for an amplifier to drive current through the load.

My thoughts too. Although, looking at the amount of space required for each channel to have a balanced output of 4 panels, I'm not sure it's practical for a home theater setup with 5.1 channels, let alone 7.1 or higher with Atmos or DTS:X. Seems like something better for a 2.1 channel music listening room. By size alone, these things seem like they could fill a room with sound very nicely in 2.1. I'll have to keep looking through his channel to see if he ever gets good results from smaller panels.

[@zappedguy]

This video popped up on my recommendations and I was instantly intrigued. I have been an audio enthusiast for 60 years and appreciate good sound. While on a very limited budget I have built several "controversial" designs (Remember the Sweet 16 speaker? If you don't and want to hear about it, let me know). I worked for a time in the sixty's at a store selling the most expensive top of the line audio equipment and have seen many interesting and wonderfully sounding speaker designs over the years. I was amazed by a very tiny transducer attached to a styrofoam cooler being demoed and sold at a state fair a few years ago, so when I saw this video, it grabbed my attention. I didn't look for much bass response in this design, but I was VERY impressed with the clarity and presence of the sound samples on the video, especially in the number with the orchestral strings. My sound system is excellent and the compressed youtube audio still allowed me to hear the detail and subtle nuances in the recording. I'm planning to play with this concept soon; it seems like fun and I want to see how impressive it may be. I spent a long time reading all the comments on this video and had to laugh at many of the negative comments posted by self-identified audiophiles that buy the most expensive gear and engineers that like to use numbers to determine the quality of sound. And laughed at the young guys that think that sound quality is bad if their ears don't bleed, lol. Hey, I like to feel the music too, but I want the bass to be clean! The quality is in the listening! ! I don't buy a speaker for it's price, name, reputation, size, wattage, specs or anything other than how well it sounds. I have found excellent sound from very inexpensive gear. (And crappy sound from overpriced and overrated gear). Keep up the good work and don't listen to the egotists that like to criticize every little aspect of your video.

@@jadedandbitter Sorry I didn't see your comment sooner. If you add up the area of the cones of the 16 speakers, you will find that it is similar in area to an 18 inch woofer. The last set I built was used in a DJ type situation, and the low end was very powerful.

[@MrExNavy]

Definitely NOT clickbait as some here have said. You put a lot of effort and research into this and I think these are awesome speakers and you can't beat the cost to build them. Very well done. I'm gonna build some to put in my shop and probably for our house too. Love your channel.

[@briansture4353]

Some people fit them into their listening chair to feel the bass as well as hear it.

[@stevenwilgus8982]

I'm going to build some: I'm a travel nurse and ICU Covid nurse and these in one form or another will be a real blast. Thank you!!!!!

[@gearstil]

I was not interested in any speaker building at all. But after seeing other videos in this channel, I realized that every subject that you approach become interesting, by the clearness and also the depth of your explanations. You are not just making projects, you make others understand the scientific principles behind it. I am not interested in lasers also. But guess what... I thing I`ll enjoy those videos too.

[@eaglesphiladelphia1933]

Your channel deserves more than a million subscribers! Considering there are a lot of channels here on KZbin not deserving of a million subscribers. You know who you are.

[@villageidiot6537]

I followed your specs exactly and even bought the drivers and experienced an unitorable midrange SHOUT.

[@AquarianSoulTimeTraveler]

Holy crap that sounds absolutely amazing!

[@sriharsha2931]

I expected to see how these peaks and troughs from different panels balance each other when used in a combination. It would have been nice to see that frequency sweep for the combination as well. Otherwise, very clear and fascinating. Thanks

[@Colnago1613]

For 40 years I'm building traditional speakers, I mean speakers in a wooden box. I did a couple of working in the air. Personally, I made speakers of 180 cm high and 300 l volumes. I used the Visaton TIW 400 for bass to 100Hz, WSP 21S (100-600Hz), DSM50FFL (600-4500Hz) and DSM25FFL (above 3500Hz). Crossower I made myself with monstruously thick wires for less resistance, in the middle and high range I switched coils of seven wires twisted into one (Tritec) ... Crossower is each weighing 9 kg. After that project I tried to make a flat panel and the result was amazing. I'm not satisfied with the only range in the bass area because I miss the punch. The project I continued on as a model for Martin Logan as a hybrid .... for the bass area I used a classic bass box for medium and high tones from the panel I made earlier. The result is excellent, but the problem is the difference in the SPL and the two components .... I am now solving two separate amplifiers because I also power my speakers with two amplifiers .... for the bass area I tried out many different speakers and the best results I received from JBL extracted from FLIP 4 ..... I know that many speaker manufacturers are skeptical when they see what can be done with much less money because they lose profits. But the speaker's self-construction has always yielded better results, about a 1/10 ratio. My friend for a couple of B & W paid $ 30000 and after listening to my speakers he wanted B & W to return to the English because he felt deceived. Thank you for the project..... The sound at recording is a bit weaker but it does not diminish the value of your project .....

[@pvancaulart6921]

Compelling, an elegant advancement of acoustic art and science. Well done and very much appreciated. Thanks for rekindling an interest that left me years ago. This technology creates possibilities for recovering sonic realism from recordings. Specifically, using various panels optimized so the sound field of original recordings is recovered aurally from any listening position. I did this decades ago with traditional drivers and 12dB/octave X-overs. That version was included into the original Cineplex Toronto theatre. Now it’s synthetically done with computers, but I’m certain these panels could inexpensively duplicate an “audio hologram.”

[@bramey0528]

That is amazing! Thanks for sharing this.

[@NickP333]

WOW! That was a phenomenal display of the magic of acoustics and resonance. I own a very expensive pair of spkrs for my HiFi system, but I still have to make these! I can only imagine how these panels would sound with a set or even one subwoofer. You have certainly stolen one of my upcoming weekends, which I thank you very much for!

[@MisterRedBird]

Did you ever get around to doing it? I'd really like some other people's opinions on how they compare to a traditional hifi bookcase or powered monitor set up

[@Pweber8888]

I can't believe it! This is blowing me away!!

[@DigitalMoose]

J. B. Lansing rolled over twice in his grave. Dr. Bose smiled and suggested 9 equal drivers on each panel. (Humor)

Ill bet if you made a short summary version to accompany each full video that would draw a lof more people in. Like with your videos on MHD if you just showed liquid metal flowing up hill and titled it "WTF i broke physics" youd get a million clicks in no time. Totally understand if you dont want to degrade yourself though!

[@adem5178]

Really interesting stuff, thank you! But I was wondering what doing a modal analysis of the placement of the actuators on the various panels would yield in terms of helping refine the 2/5+3/5 rule and optimizing the shapes. Did you ever consider doing such an analysis and also what incorporating braces or stiffeners would do to the acoustic properties similar to what is done in conventional speakers?

[@alisioardiona727]

I've never been interested in sound systems but this video makes me want to build one.

[@TheChzoronzon]

​@@TechIngredients Same as Rachel a bit above, I would love to see frequency response charts and a plot of max SPL by frequency, you compare them to bookshelf speakers but lets see some specific figures. :) and polar radiation dispersion plots if you have them (you should at least have some data on the subject, unless you have never moved the mic for some reason...) please It takes out a bit of value from the vid when you ignore all request for specific numbers, it's somewhat suspicious... but you give a Like or answer to posts that are just uncritical praise

[@tomijohannes]

I made it! My first DIY project from this channel and I couldn't be more happy! Used Dayton Audio DAEX25 exciters. Next stop: subwoofer.

[@JasonWeismannminnesotasmusic]

Do they sound as good as he claims?

[@MrRolnicek]

I am also thinking about doing something like this but have no idea how to do the amps and the woofer. This build would fit awesomely on my slanted wall above my computer for the 2 front ones and the center and I could hand the rear ones horizontally where they wouldn't stick out much.

[@papiwe1]

Can you explain how to power them and sub woofer.

[@pintfetzer3461]

nice i will made them to in combi with the sound panels,this guys soooo great,this is the kind of teacher i liked back in time^^

[@SmartassEyebrows]

@@JasonWeismannminnesotasmusic They honestly do. Better than I ever expected, even taking his claims full face. For instance, he doesn't really mention that the physics of vibrating the panels directly makes them act like how actual musical instruments work -- but this also means not only can they do the subtle reverb, but they can respond -faster- to sound changes than any cone. There are features in the music I listen to I never knew I wasn't hearing till I made this setup. It was a big surprise. Also, makes voice remarkably real, and you can hear the wavering undertones from voices that you can't with cones (but do hear in person). Actually, I've found these are so good and reproducing sound, I can now very distinctly and obviously hear the different quality of the microphones being used, and the different room spaces of recordings -- I don't mean in a strain your ears sort of "yeah, ok, I can hear it, but maybe it's just their different voices" way, but stark affects on the audio from different recordings where you can very much, "in your face" tell what sort of mic was being used. Another surprise.

[@joeb3300]

A great video, as always. I do wish that you had shown the frequency response of the combined 4 panels. I would have been interested in to what degree the resulting response was flatter. The sound produced seemed good. I’m about to experiment with a single, low-cost (and low power) exciter - I'm looking for an improvement over the internal, ~3” speaker in an amateur radio transceiver whose characteristics, when combined with the RF noise on the HF bands, makes hearing distant stations a real challenge.
