Ultra Expensive, but ULTIMATE(?) Subwoofer!

You've hit the point here.

1) The vast majority of us don't even have an audio source capable of producing 1hz sounds. The vast majority of audio formats don't support sounds outside of human hearing.
2) The microphones used to record the sound won't support sound that low either

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:

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?

Practical? No. But then, when were we known for choosing something practical over something awesome?

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

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.

That assumes you have a signal with data under 40hz going into it.

Noone does.

Edit: You might have a signal of 20hz or higher going into it. At best.

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*

A friend of mine did a video project for a show in a museum here that bottomed out at 10hz only because he couldn't find equipment that would go lower. Having experienced the video myself, it was pretty cool! It's kind of a weird feeling when you stop hearing a bass wave and start feeling it instead. 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
