Brace yourselves.. this bad boy drops to 1hz. Yes, 1hz.
Pricey, but AWESOME.
Anyone here care to build one?

I. Want. One. *drools*
I wanna hear one in action. So far all I could find were terrible examples on youtube where it just sounds like someone is hitting the wall. http://www.youtube.com/watch?v=oJ2nF...eature=related
Interesting; I remember reading about these a while ago somewhere else. I also looked for some video examples, and after finding several 'demonstration videos' by various people, I have to wonder if their cameras just aren't picking up the sound correctly, because all I'm hearing is flapping panels.
Actually the human ear can only distinguish down to 20 hz. anything below that is only the sound of the air moving. so that is kinda pointless.
Man, back in the day I had some amps that would have loved to been hooked up to 2 of those!
You can FEEL lower than 20hz. :)Quote:

I think this was out around 2002..?
That was the concept behind these;Quote:

ALSO, the Buttkickers do not produce audio. A quote from their website:
"ButtKicker brand low frequency audio transducers are musically accurate, powerful, virtually indestructible and patented linear transducers, which recreate amplified audio signals in the feeling range. They are similar to loudspeakers, but instead of moving a cone, and transferring sound waves through the air, they attache to seats, floors, platforms, etc, and send low frequency sound directly into the listener's body."
No sound, just feeling. The device in the OP is a speaker capable of ultra low excursion, lower even than the buttkicker (5-200hz). As mentioned above, 1hz is ridiculously low, and rarely would be have much program information in that range, AFAIK, home theatre source materials dont even carry information that low, meaning a subsonic synthesizer would be necessary to replicate all bass material in the lower frequencies in an even lower range (ie 1 -2 octaves lower).
Practical? No. But then, when were we known for choosing something practical over something awesome?
You've hit the point here.Quote:

Okay, so at points 1 and 2 we've established you're going to have a hell of a time even finding a 1hz signal to send to this thing, moving us onto my final point:
3) Feel. Sure, I can accept we're missing things in movies - the feel of the wind, the smell of a prison camp - but surely this isn't going to bridge that gap. All you'd get, at best, is your sound would have more presence and you'd feel changes in air pressure through your body a little. I'd suggest you'd struggle to notice it, given you can't even hear it.
Of course that's mooted by the fact that nobody has an audio source capable of producing frequency that low. Here's the sort of mic that is used on film and tv:
http://www.markertek.co.uk/Catalog/C...s/MKH416-P48U3
Goes down to 40hz.
This product is moronic at best.
...So the answer is to make up the sound? That's not accurate reproduction is it? Is a subsonic synthesiser even a real thing?Quote:

It's not awesome, it doesn't even do anything useful.Quote:

Sure it does! Up to 40hz, it produces far more output than a standard coned subwoofer. If you are building a theatre (not just a home theatre), this device (one of these devices actually!) is capable of 110db from 1-32hz, and up slightly from there, to about 40hz, when a standard coned woofer overtakes it for output.Quote:

I'm trying to find the freq. range for different source materials to see how much information there actually is in that low range.
Some sites have said that redbook cd goes as low as 20hz, but it really depends on the material; violins will never play that low, though pipe organs DEFINITELY do. (and lower)
I'm pretty sure this is aimed at high end installations and professional audio installs anyways. Either way, the technology is cool. Even when I can afford it, I wont buy one.. but I'd love to experience it anyways. Apparently the visitor center in Niagra Falls bought 6 of them for an install. :D
8D ...I just had an awesome idea.... *runs off to find a source for cheap large diameter pipe*Quote:

If this were targeted at the home theater enthusiast, I'd agree that it would be a useless product...however, it's not. This product allows those that want to go lower than 10hz to do so.
I'd put one in my home theater :D
