The December issue of Electronic Products jas a review of a new Linear Array
Transducer (LAT) subwoofer from a Cupertino company called Tymphany. It's a
linear array of of dipahragms driven by motors at the ends of the tubular
structure. They're available in sizes from 15x6.5 cm (40-4000 Hz, 100W - 108
dB) to 15x61 cm (16-300 Hz, 600W - 124 dB). One attribute claimed is that the
elements move as much air as a much larger conventional driver but with less
shaking of nearby components.

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.

Kind of a variation on Tom Danley's vane technology, including the Cyclone
driver from Phoenix(auto sound) a few years ago. The benefit of canceling
forces by having a symmetric design has always been a part of the Servodrive
mechanism.

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?

Ken,

Nice to see you a posting from you-it's been a long trip from the old
forums.

Best regards,

John Halliburton

Thanks!

A long trip, yet still eerily familiar.....
