The last I heard, a bunch of people were making some version of the rotary fan woofer to varying degrees.

Personally, after sREWing around a bunch and setting up my dual 18 IB, I don't think the ultra-low frequencies are necessary anyway.

What I mean is that, I can't hear or feel these very-low effects under 25 Hz or so. Maybe it was the series of Van Halen (I'm talking pre-sammy, pre-1984, *real* rock) concerts.

In any case, I'm thinking if I want true LFE, it'll have to be with buttkickers, or somesuch. Doing it through the air is just too inefficient.

Since the old comparison I used to do with theaters was "is my sound better that what I'd get at a theater", I passed the "absolutely, yes" mark a while ago. I don't think any theater has such a contraption, so I'm wondering who is using this stuff anyway?
