New subwoofer technology
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. http://www.tymphany.com -Jay -- x------- Jay Kadis ------- x---- Jay's Attic Studio ------x x Lecturer, Audio Engineer x Dexter Records x x CCRMA, Stanford University x http://www.offbeats.com/ x x---------- http://ccrma.stanford.edu/~jay/ ------------x |

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. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

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. Best regards, John Halliburton |

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? -k www.aural.org www.tymphany.com |

Ken,
Nice to see you a posting from you-it's been a long trip from the old forums. Best regards, John Halliburton |
