Hey all... longtime lurker, don't post much. I've found a lot of help here over the years; maybe you guys can help out some more.
I recently purchased some home theater equipment during the Black Friday week. Here is my setup:
Receiver: Yamaha RX-V671
Speakers: Klipsch HDT 1000
Subwoofer cable: Mediabridge Subwoofer cable
The sub itself is a Klipsch RPW-10
I hooked everything up, did the YPAO setup, and the first time I got a W-1 Error: out of phase. I checked the phase on the sub and it was set to 0 degrees, so I set it to 180, and got the same error. Switched back to 0 and the error went away. I thought this was odd, but it also said some speakers were reverse wired the first time (which they're not) and not the second. However, I also got a "W-3" error, which I have been unable to find anything about. It also set my sub to -10dB (minimum) and it was highlighted red. I have no idea what this means, but it seemed like the sub wasn't very loud, so I pushed it up to -5. I set the crossover to 120Hz as recommended in the manual, and I have the lowpass on the sub itself set to 120Hz as well. Everything was working fine for the first few days, though it did feel like the sub was kind of weak/nonexistent while watching cable. Fine while watching Blu-Rays through my PS3, though.
Then yesterday, I started getting static/popping from the sub when it would get a bass signal, and then it would randomly cut out, producing no sound at all. It's kind of hard to describe, but it doesn't sound like it's blown. Imagine that every time there's the kick of a bass drum, for instance, it's weak bass with some static-y popping. But sometimes it's perfectly fine and really strong for several minutes. I messed with the crossover and the LPF, made sure the cable was connected to the LFE channel securely, made sure it was connected to the receiver securely, tried switching the phase, reversed the cable... nothing worked. Thinking it may be a bad cable, I tried to just use another RCA cable from a component cable set short term (not as good as a subwoofer cable, but a decent, shielded, gold-plated set). This did nothing... same problems, so I don't think it's the cable.
So now I'm stuck and confused... is it a problem with the sub? The receiver? My configuration? I don't have another receiver to test the sub, nor do I have another sub to test the receiver. Returning them will be a pain since I bought them both from Amazon, but obviously I'll do what I have to. I just want to make sure I'm not missing something obvious here. For reference, I had everything plugged into the same surge protector, along with my TV, PS3, cable box, as well as my modem/router; I thought maybe this was causing some issue so I plugged it into its own outlet with no change. I don't think it's a ground loop issue since I don't hear a constant hum from the sub or any of the speakers. Kind of at a loss.
Thanks in advance for your help.
