Is this possible ? Or just another snake oil ?

World's most amazing subwoofer has no woofer | The Audiophiliac - CNET News

13k for the hardware and 25k for config and installation

I've heard about this before. This is definitely possible from a physics standpoint but I wouldn't know how it sounds. I'm sure it's amazing for very low frequencies but I'm not sure how fast it would be at higher ones.

There had been some write-ups before, I think ET may have had this at a show of some sort. But this had to be over a year ago, it's odd that there hasn't been as much press.....

Eminent Tech aren't exactly con artists as far as I can tell. Whether it sounds good or integrates well into a regular speaker setup though... dunno.

If my understanding is correct (please feel free to inform me otherwise), it's based on standing waves, so is probably good for depth of frequency and magnitude, but not on agility and speed, so probably better for home theat(e)r(e) (which is the less pretentious way of spelling it? I can no longer tell) than for music.

This could be cool for movies, but how many sound engineers are likely to incorporate 11 Hz effects in their soundtracks?

[Dusty Chalk]

All of them? It's gotten to the point where they use it to add tension, purely, without even bothering to incorporate it into either the music, or the background sounds of what is actually going on on-screen.

Subsonic frequencies are present in movies, though it's not too common. Dusty is right though, there seems to be a trend lately for movies to throw in low frequencies just for the sake of increasing tension...but I'm not sure just how low those notes they are using to do that reach. SVS has a good selection of waterfall charts to give a visual of how deep some movies/music tracks go:

I never realized Blue Man Group - PVC had such low frequencies, strong 10hz presence:

It's not only possible, but it's been done before. Phoenix Gold introduced a rotary type subwoofer for car audio applications some years back...

Damn, swt beat me to it. I remember companies fiddling with this technology back in the 90s. Apogee may have even been involved. Part of this came along as car audio subs were on the rise and available space wasn't.
