CB sometimes if it is a cabling issue you can grab the RCA cables and gently move them to see if you hear anything odd. I've had to replace a few over the years. Describing the noise as "buzzing" though stumps me. Usually I've heard static and drop outs with the bad RCA cables.

 

they claim to be going through it tip to stern

i'm wondering if this is a thing?

this is a theory from a guy who just likes to hang out with guys who actually know their ****, I do not know my ****...just a little ****

anyhow

I think it's a slight imperfections with the speaker that manifests itself after the speaker has warmed up a bit....i know that materials contract and expand, but I don't know how that effects speakers....when you first start up the system, it sounds good for a spell, on low or on high.....but over time, the problem starts becoming more consistent

 

they just called, one of the speakers was 'bad'

he said the cone had come loose

I'll likely get it picked up soon, anything I might want to ask about? I'd be happy to tell them....hey the experts at HDforums Audio want to know (fill in the blank)
