Not quite sure. For the TV-table/center/sub combination, Peerless have a new ringradiator tweeter with neo-magnet. I plan on using two 5" units, too, might also end up with Peerless. And Peerless probably will have to do the subwoofer job also. They have a nice 10", that would suit the expected volume of the box nicely. Working on a budget, these units seem to offer a nice price/quality relation. Peerless also have good XXLS 12" units that would fit, but they cost 3½ times more, and I really don't need that kind of sound pressure - living in a flat, with a modest size room.There's also a Peerless/Vifa based kit, I might use that for front sides - it has a 6½" Peerless and the Vifa DX dome (I think it's the same used in the Pi2's). Only thing is, the DX has to reasonably match the Peerless ring radiator in sound - I want a front that's homogenous. But the larger 6½" unit would be nice, when playing music in direct or 2.1 mode.
