I just purchase several new polk speakers and here is my setup:
Surround bar 50 (I use 3 channels of it for L, C, R)
Surround Backs: - RC 80i x2
Surround Sides: - FXI A4 x2
Sub: PSW 110
Pioneer VSX-919AH-K 7.1 reciever - 120W/channel
I hooked everything up and ran the MCACC setup program on the reciever without issue. The problem is when music or anything for that matter plays the surround sides are very quiet, so much so that you have to put you head right beside to hear them and the surround backs are virtually silent. The R, L, C, and sub all sounded great.
I tried adjusting the reciever settings and changed the DB levels for the individual speakers to try and compensate which helped some, but it was still very poor.
Next I changed the crossover settings from 80hz to 50hz since I figured that the larger speakers for the surrounds can handle a greater frequency range than the smaller front speakers. The results here were very impressive. Full rich sound filled the room, however after a few minutes (maybe 10-15) of this my reciever shuts itself off every time. Now the receiver has light on which says to take it in for repairs. Could changing the crossover settings damage the amp?
I have checked the receiver settings and the speakers are set to 8ohm and it should have plenty of power to handle these speakers. I've also double and triple checked the wiring and that is definitely correct. What could be causing these issues? The pioneer rep says that most likely one of the new speakers is defective (wants to put an ohm meter on it and prove its not 8ohm) and has damaged the amp. Any suggestions on how to fix this? Thanks for any help or suggestions.
