This is my system from the Client's eye view:
The speaker system is the BOSE PAS system (two units, one left and one right for stereo imagery).
Each side consists of the bottom (L1) stand, a 6' speaker tower (2 separate 3' sections of 12 speakers each called cylindrical radiators) and two (B1) sub woofers.
The L1 support stand that sits flat on the floor is also the amp consisting of a 250 watt high end amp, 250 watt midrange amp and 250 sub-woofer amp, all in one. The L1 contains an internal system tri-amp EQ, 2-XLR inputs, 2-1/4" phono inputs, and a bunch of other stuff I don't use and know nothing about.
Specifications? No clue. Don't care. Unimportant because I wouldn't understand them anyway. All I care about is "How do they sound to me, how does clients and guests react to the sound, how big an event can these puppies deliver to, and what makes these so different from anything else anywhere."
5 stars every category.
Trying to verbalize the propagation properties, absolute clarity, incredible portability, internal protection for distortion & clipping, phenomenal room size coverage, etc would be like trying to explain a climax to a virgin. Gotta see it and do it for yourself.
