Very nice! How tall is the sub/center combo? That particular combo looks a bit odd, but otherwise they look fantastic 
. Can't wait for the final product. Hopefully it will be ready for RMAF this year.
Yea... I agree. I designed them all to have good lines when placed vertically on top of the sub module but the standard center placement of the same speaker doesn't look as elegant. It is about 34" to the top of the enclosure when it is placed on a sub module.
The acoustical reasoning for this approach is to have a true distributed subwoofer setup. At least in the bandwidth where room issues cause significant irregularities the distributed subs really improve frequency response issues and you get much better optimization of the room response for all listening positions. I'd say it's better than you can achieve with PEQ & equalization of a single unit.
I also have complete control over the crossover between the sub and the main speaker, giving much better results than a generic 80Hz LP/HP filter combination you either see used in receivers for HT applications and better results than a generic plate amplifier with a simple variable filter. From 25Hz & up you have simply staggering amounts of in-room output with an array of these in a multichannel setup.
I'm still planning a dedicated subwoofer for HT applications. Everyone needs a Maelstrom-X, with a couple PRs to reach down into the teens to get that last bit of bandwidth that a speaker this size just isn't capable of achieving.
