I have no doubt that they sound good, and personally I find towers sexy as hell. Reading about them at their website now. They claim output capability better than 2x18 inch ported subs. Expensive and complicated way to achieve that, but I'm fond of the modular solution.
I see now that you can place the woofs wherever you like, which is good. Still baffled by the configuration of BMTMB of the mains, though. Lobe-heaven or clever design?
I'm disappointed that there's no actual measurements of the speakers themselves on their website, only from the ICE-modules used.
