This was a demonstration built by graduate students at the University of Wisconsin -Madison in 2011. It's purpose was to be physically large so elementary school kids could look inside while it was running and illustrate the how a speaker works on a grand scale (hence a transparent cone). Although powerful, it was not designed to be competitive with state of the art sub woofer systems or be high audio quality. Documentation of the build process may be found at: ludoislabs.com/giant-speaker/

@keithmoriyama5421
@keithmoriyama5421 Жыл бұрын
That will give you way better bass than this ridiculous contraption. Certain speaker dimensions give unique sound signatures relative to their drivers. Dual 15's give some of the best bass response period. The cone surface area is an idea trade off between massive low end, and 'quick' attack. Coupling 2 drivers also gives you a 'sum' and concussion that a single driver just can't deliver. There is also an important secondary bonus that even audiophiles are not aware of. The natural resonance of a 15" is 60Hz-- which is also the natural resonant frequency of a 22" bass drum. The Famous Neve company of audio consoles deliberately uses 63Hz as their low end EQ for that very reason.

It's all quite complicated. But in fact, you need to have the most rigid design with a minimum mass and well-suppressed internal vibration modes. Не просто конус из карбонового волокна (он обладает неприятными модами резонансов), но и структруированный с учётом архитектурной жёсткости и внутренним скоростям звука в основных используемых материалах. Это всё достаточно сложно. Но по сути нужно иметь максимально жёсткую конструкцию с минимальной массой и хорошо подавленными внутренними модами колебаний.

If you did all of that it would still suck. All membranes and resonant air space enclosures have an 'ideal' combination of size, cone surface area and electromagnetic properties of the motor. This applies not only to speakers but, musical instruments. For example a 14" x 22" kick drum has a natural resonant frequency of 60Hz. Even changing the heads will still cause that instrument to maintain it's natural resonance. The larger the diaphragm the slower and more inarticulate the response. The larger the surface area, the more the upper range 'beams.' That's why tweeters are small.
@nobody8717
@nobody8717 Жыл бұрын
@@keithmoriyama5421 That's solved with using a multiple-voice coil setup, distributed radially, in combination with a more rigid substrate. Apply additional coils at resonant negative zones, and with some delay tweaking individually, you can harmonize the entire surface. Essentially, yes it would suck, if you **only** use a single coil. Think outside the box next time. Thought this was engineering, not insanity. If it's too floppy to move at once, grab it in more places and shake it harder.

That thing is pure madness! it needs it's own nuclear power plant but I thought it would get closer to 5-10hz. Mid 30's is a bit disappointing. I thinks it needs some re-engineering behind the cone. I would look at getting rid of the rubber ring and use some kind of ribbed-like spars like spokes on a bike to help suspend the cone.

Thanks for sharing. Your intuition of the 5-10Hz is about right. It self resonates at 4 or 5 Hz and tries to tear itself apart if we approach those frequencies. The 30 Hz we played with corresponded to the frequency of the room where the windows rattled fairly well. The whole thing was made from stuff we had laying around in our shops, we've got about $350 in it aside from the equipment/parts we had on hand (The team members do research in power electronics and electric motors, not audio). The team that made it built it over a couple weekends. The cone material needed to be transparent so kids who were coming through for UW engineering expo could look inside it: UW-Madison Engineering Expo 2011. The poly carbonate cone material used is really a performance downgrade since poly-carbonate is heavy and not stiff enough for the size without any additional structural support (spokes or ribs or something like them). But we weren't going for performance, more so 4th and 5th grader satisfaction in a limited amount of time and $$$. This video above is some pre-event testing we did.

Daniel Ludois I'm no engineer so I wont pretend to be some know-it-all subwoofer guru but I do think you guys might be on to something! There could be a market for super sized super-powerful subs like this one albeit at about half the diameter. You may need your own custom amp too. Here's the scenario. In my dedicated theater I would hide my speakers behind an acoustically transparent screen. The center speaker would rest just above one of your "Wall buster Subs" (in-house name - The neighbor hater). I might even put a second one in the back behind a false wall. Bass bliss baby! If you guys do go for it and market a "Wall buster" product I just want one second generation sub 2nd from your top-of-the-line model. Deal? PLEASE? That being said thank you for your response and for being civil. We both know civility is in very short supply on the net these days. Think about it guys and think outside the box. You're all awesome...

FrakU2 If they cost any less than they did they would be even worse. "Not cheap" was the wrong words, *bad value* would have been better. As you can get better performance from more practical sizes of drivers for the same price, if that wasn't the case then 32" drivers would be flying off the shelves.

a club in cape town built the dancefloor over a single 35-ft cone from 2x 18" subs. then they replaced everything glass with plastic but the building started to disintegrate so it was dismantled. When you've built a mountain out of Peavey SP100 subs, you know what it means to move a lot of air.

Now build a concrete enclosure with proper accoustic properties to match the speaker,build it outside and get some specialy recorded tracks,with ultra low freq,well below the 20hz norm for demonstration, so people can feel the low frequency,would make a good crowd puller. Awesome build.
