@@TechIngredients Now I have so many questions! Could DynaMat be used instead? Could you get the same damping by gluing the veneer pane on the outside? Could I take a good pair of vintage speakers and apply these techniques to make them better?

@@warrenbell950Depending on the vintage speakers, there is a good chance that the cabinet resonance was leveraged to augment the drivers - the crossovers may also have been chosen to address cabinet resonance. I generally wouldn't recommend it as a treatment for vintage speakers - either they are good, and you stand to ruin them, or they are bad, and they aren't worth the effort IMHO. DynaMat is a choice, but not as good as the 2part treatment he used - you can also pick up a similar material from box stores used to line potable water tanks - it is nearly identical and has the same properties; you can also buy smaller quantities for testing. I personally don't love VT speakers, but the science behind them as well as the wonderful detail of the video makes this a fantastic choice for an educational channel! Love it!

“Marine plywoodS” THERE’S MORE THAN ONE?!? HOW MANY MARINE PLYWOODS DO WE NEED?!?

@@DanielBrownsan Far more than you might expect. But don't worry, the final tally is based on sound engineering principles and backed up by solid research.

Please tell me how make good box for speaker pioneer size 6/9 And what best wood use for that

@@ahmadalardah4198 Get the T/S parameters for your speaker, use software like WinISD to calculate box dimensions, and then use MDF/HDF/high grade plywood (your choice).

Maxican When I was a teen I made a large rectangle cabinet for two 15-inch drivers out of quality plywood... Didn’t do any research or even know what I was doing, just hacked it together in a few hours and it sounded brilliant to me :P I guess I was too young and inexperienced to have a discerning ear for quality audio.

Did you build these how did it go and how do they sound

Don't you need to pass the final exam, publish and defend your thesis first?

you have to successfully complete the build first

He really, really should have. It is a general problem on the channel that there is too much background, though. It happened several times during the turbine series, and now this as well.

Right... lol

It would have even been worth removing the tone in post, the following explanation would be much more pleasant. Lots of free tools to do that, like ReaFIR.

Agreed. However, since it's a fixed frequency, you can move your head around a bit to find a null (if you're listening to speakers) and make it a bit less annoying. :D

ya, you can tell there is no humor in that house. No way his son is gonna step out of line.

I would have posted a reply but my roommate killed me for allowing the tone generator to continue...

hugely this. :) I wasn't gonna say anything, but since it's a thing now, I'm adding my support for turning off the signal generator once you've demonstrated the effect.

Yeah that was brutal

Look into music therapy as relates to Parkinson's. Music therapy can help with many aspects of the condition. If you play an instrument, by all means continue at it. The biggie is rhythm. If all you do is knock about on bongos or other hand drums with musical accompaniment, it will help. (It helped my Mom a lot.)

yeh, then id probably actually learn somethings. the "looks" of theese videos is kinda "gray" compared to most "youtube" stuff, but if you blink or snooze a secound you miss something valuable! is he doing this by heart without a script? thats just crazy

bunnlose you can hit the replay key if you snooze out! This guy knows what he is taking about. I’m not sure, but you can verify.

Bravo! Exactly what I was thinking when it finally ended. I would love to build these, but what did the finished curve look like? How much bass did you coax out of those little drivers? After all, you're the one with the test equipment and anechoic chamber.

@@johnny7254 the final product's performance is still a synergistic result of the source, speaker, enclosure, room, and what's in that room, and further - how that room is constructed even plays into what "you" actually hear. Everything resonates. Those resonances cause harmonic distortion. This means even your walls affect the tone of your listening room depending on how dense or flexible they are. ;)

@@MotivatedMetalworks You'll get no argument from me on anything you've written. Nevertheless, it is more than a mere matter of convention, that we derive specifications for speakers. It is the method by which we compare one loudspeaker to another. Even beyond that, given the level of detail and science brought to bear in this presentation, is absurd to leave out any measure at all, by which a viewer could assess the success of the endeavor.

@@johnny7254 fitting those beasts in his chamber isn't possible, so any response curve presented would be flawed. However, he could play them outside and get a pretty good idea. When I build speakers, I try to balance the drivers across the spectrum, and crossover points based on where the curves are most beneficial at the natural roll off points. Once that's done, I design the enclosure to meet my goals - is it a sealed box with no deep base, or can I tune a port to hit another octave lower? I don't agree with the channel's logic or validity testing on material weight/stiffness as the accelerometer was measuring an impossible occurrence with the thump test. Also, floor weight of speakers is a moot point for most applications (outside of aircraft, boats, and possibly cars), while size is often a critical design element. Doubling the speaker walls increases the outside dimension, as the inside is a calculated and highly constrained space. In most cases, MDF with proper internal bracing will outperform the same thickness plywood, while benefitting from a lower cost. Transmission lines and horns in general are the exception, but he doesn't state this or why - you can't brace a horn like a ported box, because you'll fuck it's performance up. So in these enclosures, you need stiffer materials.

@@johnny7254 Something else comes to mind when thinking about this video. About 30 years ago, Popular Mechanics had an article teaching the reader about transmission tubes, and how you could build a subwoofer out of a 4" Realistic (Radio Shack hadn't fallen off their original business model yet, at that time) woofer and PVC fittings. What the article failed to disclose is that while the micro sub would hit 40hz, it was anemic and not musical sounding doing it. Planars, infinite baffles, and line arrays all have impressive sonic qualities while also suffering some significant drawbacks. Voigt enclosures aren't exempt either, as they tend to lack authority in the bottom end, or as with folded horns, end up being gigantic enclosures to play through the whole spectrum. Voigt's share a commonality with planars and infinite baffles, in that the linear distance from the edge of the cone and the port will have a direct impact on where phase cancellation occurs. At the end of the day - there is no perfect speaker enclosure, and we need to balance our designs with regards to perfection and reality and hope we can afford the point we wish to land on between those two ends. :)

Yea, hes proud smile put a smile on my face too.... good job, really good!

I literally said; aw, he's listening to his babys!

Came here to say the same thing. I don't need to hear the sound. Your face tells the story.

my favorite part.

I would be also.

It is just a shame he did not pick a better piece of music for the demo. I found the official download for it and the bass is clipping making it distorted.

was about to write the same comment

When?

I did the same and I’d like to upgrade my cheap drivers to a foster 8 inch driver. Would you have a recommendation for a model?

I think he may have noise induced hearing loss. Doubt he noticed that he left it on.

Yah um, as smart as as he is, and as well as he explains it all, he's also, obviously, quite hard of hearing. It was incredibly difficult to pay attention to the info with that loud, high pitched tone going on.

Psshhh I was enjoying the video until he used that thing. I turned it all the way down and could hear it 2 rooms over

I couldn’t watch after he left the horn unit blasting out. ☹️

To say the worlds best speaker definitely leaves him open to criticism these are very good but can be outperformed by a full range electrostatic there is one made by the stage accompaniment company

I think I laughed a lil too hard at this. Lol

I laughed so hard I fell asleep

I think he used some fluffy clouds he made earlier lol

N1!

Came here to say exactly this. True satisfaction right there.

Best smug face 🤣

?? There was no "build" in this video.

ikr 😝

lol me too

I searched on ebay to find the same knife you used, and also stabbed out my own eye. I also consulted with my daughter to use the same knife if he ever uses the same technique in the future and she will likewise gouge out her own eye if he does this again.

Right!?!? "Whatever! This is science!"

Silly boy, you should have cut an ear off to solve the noise issue - that's what ears are for. - just follow van Gogh's example.

I cant focus on a damn thing he is saying. Something about words... Impedance matching...

my god i want to listen but its painful , forgot to turn of the khz sound

haha

haha yeah it's annoying... I turned off sound and turned on subtitles xD

How can some one so smart leave that ringing for so long

@@dougyt261 Might be much louder in recording ^^ Also while he is very fit I guess with age your higher frequency hearing is worsened so I guess for him it was just not loud at all

Thanks! The first hit is free. Now you're mine.🙂

But is it cheap?

​@@JesusFreke Relatively, yes. He explains this in the video. It's why fibreboard is used in so many cheap wooden things these days. For example, my desk is LDF and the speakers I used to haul as a DJ had a MDF enclosure.

@@JesusFreke Fair enough. Hard to tell in written communication.

Now isn't that ironic

I flip to my Schitt Modius Dac, 1/3W OTL Tube amp and some Sennheiser HD600's for his playback example - like I'll get to hear HIS speakers somehow lol :D

my setup is 3,000 watts so I might be a little close to hearing what he is hearing.

I think you mean that MICROPHONE allowed those speakers to sound decent through your speakers? (Everybody forgets about the microphones.)

Thanks! If you listen carefully near the beginning you can hear me folding my arms, it's definitely real and we're only set up in a lab.
