Need Help, Center Speaker Distorting!!!! - Blu-ray Forum

snsguy · 11-06-2010, 04:51 AM

Hey Guys, I need some help. I've been hearing more and more distortion coming from my Polk CS2. I've tried a bunch of different stuff but for the life of me I can't figure out what is causing it. It's happening a lot with Dialog. Certain scenes I am hearing a buzzing or kind of a crackling noise coming from the center speaker. It was slight but has gotten worse over time. I'm not sure if it's the receiver, which I just got back from repairs about a month ago, or the speaker itself. I've tried switching my two Monitor 60's, left and right speakers, to the center channel and will hear the same distortion but it's more tame. I've tried my back onkyo surround speakers and may or may not hear it coming from them at all. They are not the best so I'm not sure if I would here from them or not. It's really aggrivating me though because I'm hearing it a lot. I heard it a few times in Prince of Persia, I hear it a lot when watching cable and in a few other movies that we've recently watched. It's always most prominent with dialogue and it almost seems like a certain frequency. I've tried changing out the speaker cable and that didn't do anything. Any help would be appreciated.

From the way you described it, it seems your problem may still be in your receiver. Since your receiver had been sent in for repairs, that seems suspicious to me. If one of your Monitor 60s hooked up to the center is also making audible distortion, then to me it seems to pin the problem on the receiver. Now it doesn't sound like it could be your speakers, but what you could also have done was to connect your CS2 to either the left or right channel to further verify that it isn't the center.

Before you send the receiver back to whomever repaired it, try this first. If you know of a friend or buddy who has a receiver, ask him if you can borrow it. Then swap out your receiver with his. If you hear no distortion, then you know it's your receiver that's causing the problem. If you do hear distortion, then it's probably your speaker(s).

Give that a try. Good luck.
