$2,000 per speaker. I auditioned the Bose PAS(both on a gig & in a studio environment), and when used in conjunction with my Yamaha Tyros keyboard playing a stereo sampled instrument, was UNDER impressed. Then again, Uncle Dave utilizes it and claims it sounds terrific with his Yamaha PSR3000, so I suppose it's: different strokes (ears) for different folks. The only way the Bose would work for me is if I had TWO, but that would cost: $4,000. - Scott
