Clickbait? Yes!
Still interesting and worth watching? Yes!
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.
@@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! ;)
@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.

"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.
Change Tittle to: *World’s Shittiest Speakers!* = Happy Dumb CZcamsrs! 😂😂😂😂😂
One man's old ceiling tile is another man's world's best speaker.
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.
You did all that but have no way to measure the result?
@@drummerdoingstuff5020 😂 Worth it!
Sounds fantastic!
I'm quite fascinated with this experiment and I'd love to see data. Do you have a nearby university with an oscilloscope?
Did you compare the given method vs your own golden ratio method?
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!
You're welcome!
Check out some of other videos. This isn't unique.
@@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 ^^
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.
@@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.
We’re build a recording studio. Do you think this would work good in a space that’s about 25 feet long? The room is about 5’ x 15’ x 25’. Triangular like.
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!
Amazing idea on the hanging artwork!
That was exactly my idea too that would be great
Does acrylic paint , mess up the sound ?
@@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.
@@Leaf_man simple solution. Mount the panels behind art so the panels are free floating accents on the art.
"Sometimes I think I'm smarter than I really am"
After discovering your channel, this is a thought that I constantly have.
No kidding.
You aren't smarter than a fifth grader.
I am way not as smart as I thought I was.
Ah the Dunning Kruger effect.
@@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."
Anybody else impressed with the workspace itself? That place is huge!

@@lucasrem hey man I used to have one of those and it served me well!
Looks like the inside of a barn loft or a Quonset hut(spelling) that is beautifully decorated and taken care of
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.
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
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.
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.
@@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.
No joke, you are my hero. I am in my first year out of school working as an electrical engineer. You are the prime example of taking the principles we learn in school and putting them into action with REAL projects. I hope I can develop a clarity of thought and precise-ness of explanation as you demonstrate in all your videos. Thanks for being so thorough and for having such a broad range of projects!
Thanks!
You've got the right idea.
Just finished this speaker wall; 99% the same, on a wall in my garage. This is everything he says it is. Turned up base. Music is more fun than ever before. In one word “Clarity”! If you don’t do this, I question your motivation for life (sound at least)!
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...
@@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.
what if it made in half size ? ty
It’s spelled “bass.”
Base....LOL
4 dollar 25w dayton audio exciters. oh my. What a world we used to live in. They seem to be about $20-25 now. I should have built these when i first saw these videos.
I snagged a pair of the little three legged 5w ones for $20. I appreciate you taking the time to make such an informative and thorough video series. Time to finally try it out. Wish me luck! :)
Excellent, a thorough explanation and presentation of a complex subject. You are having as much fun making these videos as we are watching them. Hats off.
I just want to say your research has proven to be invaluable to me during my final year in uni. I'm very grateful that you would share this information to the public. This has been the basis for my final year project.
Nice,
If you after cheap actuators go to a car wrecker and have a look at the roof linings, some vehicles use these to active noise cancel vehicle noise.
@@Steve211Ucdhihifvshi Mercedes-Benz uses them for audio in their newer vehicles. Toyota also has some in the roof of their SUVs

Genius comment!
It’s incredible how some people won’t get that you’re making a joke, no matter how blatantly obvious you make it to them.
Great video and a cool DIY idea. Together with the first part of the speaker series you made and all the research that went in it truly amazing. Thank you for putting this all together!
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.
Some people fit them into their listening chair to feel the bass as well as hear it.
It would be awesome if you did a DIY subwoofer as a compliment to this video.
Please, I would love to see a whole surround sound setup
@@BoozeBelly ditto
up up
Yes!!!
Seems like you could get some $3-$6 exciters and make some rear surround speakers pretty easy, following a similar formula to what is shown here. Maybe use smaller (or thinner?) piece of foam with smaller exciter. Maybe make them SMALL using acrylic or something like that, to make them blend into the surroundings?
At 10:13, "I'm a little bit compulsive", oh really!!!, after watching many of your videos...I would have never known. LOL.
However thats what makes your construction and analysis so precise,...soo be compulsive and be precise. It's the best way to be!!! I always enjoy your projects, hope you don't mind my kidding!
Lol. I thought of the sbl skit " The Anal Retentive Carpenter" skit on SNL.
I can't believe how good these sound! They're so unconventional and cheap. Thanks!
This is the binge watch type of channel that keeps you from getting any actual work done... Very impressive. Looking forward to being lazy for a long time! Keep it coming...
But it only works on certain people, like me and you. I love this channel.
It’s interesting to me. About a year ago I bought a Thunderpuck Bluetooth speaker. Essentially the same thing but you can set it on just about any surface and listen to the different dynamics of each material.

@@dredrotten WTF?
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!
My daughter who has a home studio set up shared this link with me and I ended up running with this concept and just finished 4 panel acoustic speakers for my mancave. Used the Dayton exciters and added a Dayton bass speakers. Ran it through a Rockville Blutube 4 Ohm amp. Also added a Rockville 8 inch subwoofer. WOW!! I have a set of 5th Gen KRK's and some Bose 901 speakers I use for my DJ set up. But these panel speakers are my listening system choice. You made a huge dent and these DIY speakers are hot items on You Tube. Thanks!! 😎
I'd like to see the frequency response of the entire system. It would be neat to see how that graph compares to a summation of the four separate response graphs.
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.
Thanks!
Nice comment.
How does that sweet 16 setup work as a dedicated woofer? It hits 20hz, right?
How'd you get on? Any projects based on this yet/in the works?
Most of the negative comments are from audiophools.... ;)
@@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.
This is outstanding DIY jump off point! THANK YOU !
I will be screwing around and playing with this concept and having a total blast!
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 .....
Wait you're saying the JBL Flip 4 portable speaker was the best subwoofer you could find? Or am I misunderstanding?
Cool story bro...

Do they sound as good as he claims?
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.
Can you explain how to power them and sub woofer.
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^^
@@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.
This whole video is astonishingly informative, surprising, and just plain fun.
Audiophile greetings from central Poland - thank you!
You are like "Mr Wizard" for grown ups. I enjoy and appreciate the scientific edge that you put into your tests! Great videos.

I read this comment and immediately laughed, because that perfectly describes your talent as teacher and scientist. I grew up in the age of Mr. Wizard and your wit and deep technical understanding make your videos incredible! I will be building these for my kids desk areas.

The tech research deserves a thumbs up, but a second one is deserved for standing during the Halleluiah Chorus.
That is so cool I can't believe it musician and audio buff. You gave me a new hobby thanks for sharing this bless you
This was a great video and thanks for providing such a detailed analysis of the speaker profiles. Since the response of all eight panel speakers is a superposition it would have been really cool if you had summed the individual response plots or if you had recorded the same frequency sweep with all speakers working together. This would give a much more quantitative view of how flat the system response is. Either way, really great video and keep up the great work!
I REALLY Wish to see the summed results as well!! Maybe they Really Are the best speakers out there, and ~120 for a full set (of 8 drivers)
Then after doing that you write a little program that runs through every combination and give the correlation to a straight line.
I'm a redneck country boy. Lol but I made these speakers and there awesome. One modification I made a small hole through the foam that lined up with the center of the exciter. So it could breath and stay cool. Sounded much better even though I didn't think that was possible. Also says cool no matter how hard I'm playing them. Love the work you do. Please keep it going
Redneck Country Boy
so glad I found this video. If the music played was with the panels only, I am damn impressed and will start prepping to make something similar.
how do you not have more subscribers/viewers? I cannot express enough how much I hate garbage youtube videos that try, and fail, to express scientific and engineering principles properly and clearly. Thanks for doing the good work.
Thank you! Spread the word and we'll get those subscribers.😘
the only reason is most people don't really like long videos, that's why
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!

@@juancarlospalomino8939 i like long videos but i do not have the time if i want to watch more than one video.
My experience building many different types of speakers from horns to large boxes to panels has been that room acoustics and standing waves are responsible for peaks in response. I loved your experimental technique. I usually used white or pink noise to test response.

Thank you!
I built these speakers to use in conjunction with my current theater/stereo system.
The Setup: I am using two "TriTrix" (parts express) floorstanding speakers for L/R, Bowers & Wilkins for center channel and L/R surrounds. Bowers & Wilkins ASW-750 subwoofer. These panels are mounted hanging behind my TV along the wall, about 5" from the wall itself. I have everything hooked up through my receiver, using "zone 2" function to output the receivers audio into 2 additional amps (Fosi audio) which power these panel speakers.
SOUND QUALITY: AMAZING! With everything set up as described, this system ROCKS. It's almost like being at a live performance, and the sound emanates from the wall itself. I highly recommend using them BUT only to supplement your current stereo as I've done- on their own, these panels are only okay. They are not as defined in the high high range nor in the low low range as my parts express speakers I built for $300, but they are good for what they are. This is where the subwoofer and traditional speakers come in to fill the gaps. However their mid-range performance is exceptional and this is an upgrade over just using traditional speakers. I no longer have listening "sweet spots", rather the whole room is filled with sound! I used to think my system was perfect, but now when I turn the panel speakers off, it sounds like I'm listening in a vacuum, with a narrow soundstage- more like listening through headphones. Once I turn them back on, it's a whole new level of depth, like listening live...Once you try it you'll be hooked!
CONCLUSION: Definitely build these! It's a super fun project and worth the financial risk for less than $200. Plus the listening experience is unlike anything else, so it's just neat to experience. But in my opinion they aren't a replacement for a home stereo without some supplementation. Maybe just a subwoofer would do it, but I can't comment on that since I've only tried it as described. Good luck everyone and happy listening 😁

Rarely do I go to the trouble of using my “good” headphones to listen to anything on CZcams.... This was absolutely worth it.
Considering this was recorded using high quality equipment one would expected it would suffer lossless compression via CZcams. I can only imagine how much better it would be in person.
Thank you for your attention to detail, and straightforward no nonsense presentation.
*It would be interesting to explore the long term integrity of the materials both structurally & tonally.
Thanks!
At the end of our previous video on these speakers I demonstrated them in our home. They're still working well three years later.
What a great channel .. I’m making these tomorrow for my living room , I have concrete walls on two sides and can’t stand the echo , this sounds like a great solution for my kinda budget ..thank you for your knowledge and your time
They'll work even better if you hang something on the walls behind them that absorbs the sound that comes off the back of the panel. As we demonstrated in our videos on these materials, acoustic ceiling tiles are probably the best for this purpose, but a rug, blanket or a heavy curtain will help.
Outstanding. Thanks Mr. Peabody for aurally enhancing my understanding of these principals
Your channel deserves more than a million subscribers! Considering there are a lot of channels here on CZcams not deserving of a million subscribers. You know who you are.
This guy is a freak and i love it. I first discovered this channel when i was doing transmission line research. In the near future i will likely pursue this setup. When he did the sweep the high frequencies came across surprisingly clear which really got my attention. Thank you for toe efforts
I tried this on the back of a guitar and it sounds great, thanks for the idea!
i am amazed by the knowlege you have and naild every aspect of this project well done you deserve a award 👏👏👏👏👏👏
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
Love it. Been interested in making some speakers for a while now, can't believe I haven't watched these videos sooner.. great information!

Well after doing research all over the Internet and watching alot of videos like yours I finally got all of my parts together, pink foam panels high quality pure copper speaker wire, a nob sound 40 watt two channel Bluetooth mini amplifier, connected to my Amazon echo dot, high quality tidal streaming music service, I also did something not too many people talk about and I didn't think it'd make much of a difference 🤔 I used a one-to-one ratio of wood glue and water coating, two coats on the back where the Exciter goes one coat on the front and as people say at first you might be disappointed with the tinny treabley hollow sound which mine did exactly that at first but when the exciters started to slowly break in OMG these sound absolutely fantastic and yes they do not put out a lot of bass at all but the Fidelity the detail spaciousness the dimensional realism and spacious depth some songs almost spiritual like as funny as that may sound, 😱🤔 I tested them against my parts Express Dayton bookshelf speakers that have quality grade ribbon tweeters.... and they come "incredibly close" to the SAME upper airy sparkle and detail of the ribbon tweeters I would say about to 97% but as stated before it's much more than just competing with some quality tweeters the detail the realism the spaciousness the depth the Sonic imaging when built correctly is just absolutely second to none I heard some entry level Martin Logan speakers in a store some years ago and honest to God they did not have the mid-range and the treble and the open airy spaciousness dimensional impact and realism that my panel speakers when built correctly are able to do. I did all the techniques of sanding the front and back panels in One direction using only one inch panel adding the coatings, Two coats back one coat front I also used gorilla glue to help attach the 3M adhesive legs on the exciters that I bought from parts Express, to make sure all the vibrations the Exciter can produce goes into the panel, the transition and speed of the sound going from left ....right ....left ...right left ...right is VERY, so when you do all the techniques on the panels you glue down the exciters so all of the vibrations are not lost and they go to the surface and nowhere else and high quality wire a high quality streaming source and a high quality affordable amplifier and you put this all together it is absolutely amazing the sound quality the speed the depth the sound field and the overall detail that these produce are pretty mind-blowing for a complete package that is under $100 granite they don't produce a lot of bass but I will definitely take Superior sound quality depth imaging spaciousness and realism over room shake and bass, I say to some people when you listen to music on my panels you don't listen to music you experience the music I gave them every chance possible to sound the best between sanding the front and back cutting the edges on all four corners sanding the edges as well place the exciters in the offset manner as described in videos using gorilla glue to permanently Bond them to the back of the panels and then using a wood to water glue coating on the front and back then using a thick gauge high performance wiring using a little distortion high quality two channel amp using a premium hi-fi title streaming service and place in the panels in a very specific manner to where they can reflect off the back of the walls and from the edges as well I thought music sounded good when I listen to music on my limited edition pioneer speakers or my Polk audio speakers or my Dayton parts Express bookshelf speakers with a ribbon tweeters they all do sound good but they and they have good base they just can't compete with the panel speakers I built on the absolute realism that spaciousness of the panels the old adage you have to experience it in person to become a true believer but they have to be built right placing them on a cardboard box hooking them up to laptop music or low Fidelity Bluetooth amp, unfortunately will not give you the ultra premium results which I do understand to each their own👍 I wasn't expecting much when I built mine but now I don't even listen to regular speakers these ARE my primary speakers and I will probably never go back to regular speaker ever again which in itself is pretty amazing ❤️👍👍
7 months after you comment... :P Could you provide a short summary of your research? Or a list of what you actually bought? How many panels, which sizes and which exciter placements did you use?
i am genuinly amazed how i could have ignored the existence of this channel up to now... this is beyond genius
Let this be a lesson to you and your people.
I have been following this concept on your channel and I have to say it is truly inspiring, together with your brilliant explanation of not only How but Why a certain path is works. The sheer depth of research with different materials and techniques blended with good science, leads me to conclude as a "science/tech channel" yours shifts gear when others have finished.
Well Done.
I am considering this design as an extension speaker for my Amateur radio to maybe improve vocal clarity!
73 Barnie.
Fantastic video series...i really like how you present your findings in a clear understandable way. I aspire to improve my communication skills to match yours one day. I'm buying the parts now
Feeling inspired now! Excellent content as always.
Absolutely impressive, listening here with Genelec 8040a studio monitors.
Amazing info, thank you sir. Vocals really seemed to pop through these, they sound as if they would suit a home theatre setup nicely
these two videos were super fun and informative. excellently conveyed!
I followed your specs exactly and even bought the drivers and experienced an unitorable midrange SHOUT.
I learned the definition for the word "friable" many years ago and can't tell you how pleased I am to finally hear it used by someone. It made me feel smarter than I really am ;)
Crumbly
I hope I’m not the only one who imagines attaching art prints on top of these and putting them in each room of my house as a big house wide speaker system where the audio follows you from room to room
You could silk screen or a vinyl wrap but layering would change the resonance profiles.
I would think similarly to sound treatment you could do this. If you painted onto the flat wood panels as long as it wasn't thick acrylic style it really should not hurt the sound noticeably. If you could print onto a thin film and then glue this to the substrate should be fine.
@@Mr.Unacceptable considering the low mass of either I would be surprised if it changed it much, but hey, one more test to do!
I thought the same, but remember that these panels will vibrate quite a bit as the music plays. So It could get a little disturbing to look at when they are playing. If the panels are plain you will probably not see the vibration, vs. if they have a detailed print.
Projector Screen!!!
I love your channel so much. I just found it 3 days ago and have nearly watched all of your videos. Great work sir!
Thank you and welcome!
@Tech Ingredients- You should be proud!! This speaker building method has taken on a life of it's own lately! Suddenly there are many new videos on You Tube that are crediting you for introducing these simple & inexpensive DML panel speakers. Personally, I'm excited that you also showed how vibrations form various geometric patterns in the sugar you poured on excited plates. I had only seen that done once before and I am facinated by that situation because it looks just like what I have always seen in a telescope while viewing stars.
That's great!
Plus all excited are on backorder.
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.
This is one of the most interesting things I’ve ever seen!!! Thank you
I realize this video is 4+ years old at this point... but I have to say, I just finished watching the previous video and this one and I'm blown away. I would love to hear these in person, and put them up against something like a set of Magneplanar speakers (So far the best sounding, widest-stage speakers I've heard in my life)
This has given me so much to think about, and turned my plans for a new home theater system completely upside down. Thank you!
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.
I love your ability to explain your train of thought and I'm excited to try my own ideas with these - I'd previously turned my nose up at exciters. I'm trying to think out fibonacci shapes for those acoustic panels you've enlightened us to - still can't think straight 🤣
You and the unseen support effort are just wonderful.
Thanks!
I've been waiting for this follow up for months now! Yay!
Listening to this on a bose wave radio 3 and it sounds extremely good. Also took a lot of screen shots. I am sooo doing this in my house!!! Love this video!!!🤩
Have you done it yet? I am thinking "what if the panels were on opposite walls? Or panels on all 4 walls. Talk about "Surround Sound".
@@keithmarlowe5569 no I got four different books on procrastination that I got to start first. LOL I got so many irons in the fire my friend it might be awhile before I get around to doing this. But I do have the speakers on reserve on Amazon.
@@masterpanther1 I too suffer procrastination, and a case of "underestimating complexity" and thus time estimating. I bought the drivers 2 years ago for a head unit boom box, but with detachable speakers and a subwoofer. The idea being for my shop area in the basement, or can take to the garage or wherever. Then I figured I should really focus on finishing the basement, and putting the shop area together, before attempting projects. If I didn't have to work, and really knew how to finish a basement before I started, might not have taken 2 years. (still not completely finished) I also bought a small beverage fridge for steak aging, but it won't hold steady temp so it needs some modding. It was in the middle of that, after ruining soldering tips and wasting a lot of solder, I discovered I don't know how to solder. The speaker boxes required learning more about using a router than I knew before. I REALLY should stop watching CZcams for anymore damn project ideas I can do right quick.
Wow phenomenal. on the last vocal track, even on my crappy headphones I can hear a faint high pitch organ in the mix in the background!
Just made this flat panel speakers with one actuator. In this case I used the Visaton EX 80 S dynamic exciter 50W 8 Ohm. I mounted it on multiplex of 8mm thick, 120 cm x 60 cm and kept to the 2/5 - 3/5 placement. Combined with my old Yamaha RX-V471 receiver this produces an incredible good sound, I had to compensate with the inbuilt equaliser because the high frequencies dominated and the lows were a bit lacking. The sound now rivaling the sound of my Boston Accoustics 360 and those were highly aclaimed in a German audio magazine.
BlindeEzel what would you estimate is the efficiency of your speaker?
@BlindeEzel Welches Multiplex? Bitte sag Birke - will selber 2 solche Panels basteln und geöltes Birke Multiplex sieht dafür einfach mmmh aus :)
I know this is a bit old but could you explain the 2/5 3/5 rule? If i put the exciter 2/5 of the way on one side isn't it always 3/5 on the other? Also at the end he says 2/3 3/5 rule is that something different or did he misspeak
@@ThePurplePeon 2/5 from the side, 3/5 from the top. This is CLOSE to the golden rule ratio 1/1.618.
This is when a line is divided into two parts, and the longer part (a) divided by the smaller part (b) is equal to the sum of (a) + (b) divided by (a), which both equal 1.618.
A better approximation would actually be 5/13 & 8/13.
@@SJ-km5ly So basically the further up the Fibonacci sequence the closer, right?
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!
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
another deep dive into a subject that many of us really enjoy..
Great choice of music! Excellent work- I think I will make some for myself. Thank You!
Good luck!
So I finally made these speakers myself. I found that I got some GREAT sounding speakers for little cost. I replaced my previous setup and it sounds great. Thanks Tech Ingredients!
You're welcome!
Thanks for the feedback.
I can't believe it! This is blowing me away!!
Holy crap that sounds absolutely amazing!
This is so badass! thanks for putting the time and effort to make the video, im going to try this for sure!
I just want to sit in the corner of your shop and learn stuff man. You really have a lot stuff
ditto
me also ahahah
Stuff is neat
i'm always thinking the same... well, we do it "virtually" in his videos, anyway this videos are amazing
Looks like he needs at least 6 more chairs in his shop for all of us!!!
36:52 Now that's bangin music, 10/10 video.
The best channel on CZcams! Wonderful content, full of useful information. Mix Media Studio.
Fantastic effort and work,you have inspired me to build a pair
Thank you very much
I just hung a pair of the pink foam ones and they sound great!! Thanks so much for the awesome videos, you're definitely in my top 5 favorite channels ever.
Me too. Stunned. used FOAMULAR 1 in. x 2 ft. x 2 ft. R-5 Small Projects Rigid Pink Foam Board Insulation Sheathing and 40 watt version exciters.
@@YorHighness I am interested in learning whether you think they sound good as is or whether you think it should be coupled with a subwoofer?
@@johnjacquesmalan Subwoofer is needed for under 150hz yes
@@YorHighness How do they sound on lower volumes? I'm thinking about replacing my bookshelf speakers with these.
The fact that I listened through the whole listening test is, in itself I think, proof of the sound quality of these speakers. Even though (at least to my reckoning) you haven't set them up to their best potential, they sound great! Well done!
I build them, sounds good. Thank you so much for yet another great informative video. ❤
So many the I never thought I would find something that's not traditional I love It haven't watched I'm watching I'm excited to see what is going to be learned here thank you and appreciate stay strong my friend
I've never been interested in sound systems but this video makes me want to build one.
Great! It's really easy.😀
@@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
This was the video i have been waiting for! I appreciate all your hard work and passion for sound! The XPS panel is a great idea for a DIY project.
I was convinced and when I got to looking it seems that Dayton has an array of options. Mine are on their way. Thanks for sharing. I've wanted a Bluetooth speaker setup in my garage for years so with this inexpensive setup I just might get it.
