hello, Ive got a quick question. here is my situation. I run sound for my band and we have recently upgraded to a mixer/power amp set up from a powered mixer. Here is what we are using: a non-powered mixer, a dbx driverack (eq,crossover) and and ab precendent series 900 watt power amp. now heres my question. We are using two klipsch profession 15inch speakers run in parrarell, and an 18inch klipsch professionall sub. we are using one channel of the amp for the sub and the other for the 15inch speakers. The 15inch speakers are rated for 500 watts, 8ohms. and i believe the sub is rated for 450watts. Now, i know that these speakers are being underpowered with the single power amp we have. Is there any danger of damaging these speakers by underpowering them? If we are sure to keep the power amp under 3/4 power for each channel to avoid clipping, and be sure to avoid clipping at the mixer will the speakers function ok under these conditions? we tested this setup last night and we were able to get to levels we wanted without any clipping occuring.
