I mentioned this in my AES show report. This is Ken Kantor's new company.
AES Preprint 6250 has a whole lot of details about the thing.. in some
ways it's kind of like a Heil driver on steroids in that it's got a bunch
of diaphragms that move parallel to one another and squeeze air in and out
like bellows. Much massier diaphragms, though.

I can see the reduced shaking, since basically all the motion is symmetric
so the inertial forces will cancel out.

I missed the demo at the AES show because I wasn't willing to cross the
picket line into the hotel where it was being shown, though.

We were showing at the W, a non-boycotted hotel.

Hey, I'm a card-carrying Venture Socialist!

At any rate, we'll have to try again later. NY this Fall?
