Davehrab...Hey, those Russian babes really got to you! I am sorry to say that they are about 21 by now, but still quite desirable.
With regard to "safe" design decisions, military stuff is much more conservative than commercial. The consequence of error is worse (like that Chinese Embassy). Our chips, for example are larger and run slower than commercial functional equivalents (but they can fly through a nuclear fireball and still work).
My recent observations are based on planar speakers, and an unusual subwoofer array, but I think that similar results will be seen with box speakers. The important factor is a subwoofer that doesn't conk out at 100 Hz, but you would want that anyway even if you crossed over at 50 Hz.
