No doubt the BOSE are great units ... I used one a number of times when I filled in for another KB player at a certain restaurant ... the lounge was at least twice as long as it was wide and it filled the room nicely ... BUT the staff told me I SOUNDED better with my system ...
I've seen some bands using the BOSE systems and they had one for each player ... and I've seen DJs using 4 at a time ...
