I just used the Panaray system for the first time on a Grammy-winning pianist. I did my homework on the system ahead of time, hoping for no surprises. It performed great and this is not the first time I've been surprised by little Bose speakers! These were dual MA12's per side and two subs under the stage, crossed over at 140 with a Driverack and the overall EQ was smile-curved in the Driverack, as Bose recommends (not EXACTLY to their specs, but similar). Sounded pretty flat to me. The system is 160 degrees wide! A friend of mine in Virginia owns a vineyard where local noise ordinances are strict and installed a similar setup to the one I used for special events. He says it throws 85db 200 feet (but he has plenty of pump on his dance floor). So, if you have the right application these can be cool speakers.
