OT - As I wandered the LA Audio Show 2017 as expected I noticed it is devoid of any competitor to my beloved 1400 (let alone 2400), but this is not meant as criticism. This show is geared towards a certain audience - it is what it is
. There is however one product worth mentioning, not because of its output and CEA numbers, but because its technology is interesting. Intesting "good," not interesting "bad," LOL.
Wilson-Benesch Torus Infrasonic Generator, at $9.5k including amp and crossover. The following is completely AFAIK
so no flame pls :-), just correct me as needed. It has two voice coils and operates in a push pull manner, without the use of a spider. The drive is actively pulled back to position, as opposed to conventional driver where the spider does the function.
Unfortunately it is a "silent" demo as subwoofer was not hooked up. Too bad because I had with me my personal demo CD that would give me some idea of what it does. At any rate, I would have to admit, it would be so interesting to see CEA-2010
numbers for this subwoofer.
The Torus places an 18” light-weight, super-stiff, multi-axial Carbon Fibre cone at the end of a phenomenally powerful push-pull motor. Unlike a common subwoofer that relies upon a high hysteresis suspension to reset the cone to zero, the cone position in the Torus is dictated at all times by electromagnetism. The result is low frequency sound with absolute precision and integration across the frequency range.
