My setup is two RF-82's, RC52 center, S2 surrounds and a RW-12D sub. From what I gather my house had a power fluxuation since the board on my 12D fried. I got the board replaced, but only to find the sub not nearly as powerful. Previous setting on the LCD was -10/-8, currently I had to turn the sub up on the reciever (AVR247) to +5, and +5 on the LCD readout on the sub. It seems the system overall has lost some power. I'm guessing the reciever may have been damaged in the fluxuation? Before I listened comfortably around -40/-35, now i'm listening around -25/-20. At first I thought the speaker might have been damaged from the fluxuation, but through two boards i'm leaning to the reciever. Any thoughts?
Thanks in advance
