Ah yes. . . the isobaric woofer arrangement. I wish I had heard the Mani 2s, but have not had the opportunity. I would have loved to hear how the theory translates to the the experience.On a similar note Elac's new $2500 monitor, the AS-61 / Andante, is using a passive radiator in front of a smaller active woofer. Mids / Tweet is coaxial on top. Very curious about this one as well.

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.
