RE: Vince Bruzesse on Totem Cabinet Design

Posted by hahax@verizon.net on July 7, 2017 at 19:10:28:
Sorry, this has nothing to do with Isobaric which is just a way to substitute efficiency for a smaller cabinet. I was referring to the element speakers. I was told at the show they had a Bessel(minimum time delay roll off). This is fairly easy to do in a closed box by adjusting box volume to fit a driver. But in a reflex the driver has to have specific Thiel/Small values otherwise there's no way to get a Bessel function no matter what changes are made to the box size and port. But,
of course, Totem makes their own drivers for these speakers.
