I've owned a RM 6600 speaker system, complete with the PSW350 subwoofer, for many years and I absolutely love it.
Earlier this year, the PSW350 needed its amp replaced because I bought the wrong fuse and blew it up! Well, it didn't blow up, but it obviously damaged the amp. (Lesson to all on taking care of fuse choices!) Polk sent me a replacement amp and I installed it without issue. It has been working fine ever since. Until recently.
I always unplug my entertainment system whenever there is a chance of bad weather. Recently, when I plug everything back in, the PSW350 makes a horrendous sound of electrical static, fizzing, hiss...followed by a loud low-end pop that shakes the floor. Then everything is fine and silent...and the subwoofer works as it should. I never hear any of this noise except when plugging it back in. I've tried plugging it in separately from the protected power strip, and plugging it into a separate recepticle. The outlets have all been checked and are not having any issues.
Is any of this noise causing damage to the speaker? Is this something that should be expected? I could record what this sounds like if that would help. I just want this fixed. Thanks!
