Romy's bass driver array is actually a very good approach. 6 x10's per side is actually enough to produce an acoustical watt at the upper part of the range they cover, but not down to the subterranean depths of an orchestra's hall ambiance. I did not realize his former room in the basement apartment was as small as it evidently was. What about now, though ?    Actually, the point of my post was illustrate the acoustical needs for proper integration of the two types of systems. Also let me add here, I feel for domestic settings, this approach makes the most sense from a practical viewpoint.

Scott, I still do not “get” what acoustical watt is. To me it is absolutely bogus parameter. Let presume that acoustic system is abstractedly and anechoicly linear from 200 to 20hz and has some kind of reference ability to produce an acoustic pressure to a reference distance driven by 1W or electrical power. Being placed in a real room the acoustic system will be exposed to all room modes (standing waves) but let discard it.  Another factor that will be effected the real response would be the ability of room to dissipate different frequency. It might for instance produce 90dB at 8 feet and 1W and 100Hz but 70dB at 8 feet and 1W and 40Hz (we discard standing waves juts for sake of conversation). So, in this case we have a basic frequency response as an inverted characteristic of room ability to dissipate different frequency. My question is: why in this picture the concept of Acoustic Power or Acoustical Watt can advance anything? I am not being sarcastic, I just truly do not know where to use it.
