Hey guys, I'm new to the forum after I bought my second Polk Subwoofer and am having the same problems as I have with my subwoofer I'm using on my main TV.
I just bought a Yamaha RX-V473 Receiver and a speaker system which includes the Polk PSW110 Subwoofer.
I ran through the sound test with the subwoofer and it isn't working. I've had the exact same problem with a Polk Subwoofer and Yamaha receiver (older models) with my main TV and never got around to fixing it (don't ask why). I just purchased these new sets for another TV and want to solve both problems.
I have the single subwoofer cable running from the Yamaha Subwoofer input in the receiver to the R/LFE In jack in the subwoofer. I get sound from the subwoofer when I'm plugging it in, but when running the test to see that it is set up properly it doesn't work at all.
Can anyone here help? It would be greatly appreciated.
