Russound Cav6.6 problem.

Just the other day one of my zones speakers started sounding kind of horrible. I thought that the speakers had just gone bad so I got a new pair and it did not change anything. I have moved the wires around and tried all sorts of things. I will be trying other things too but was wondering if anyone has ever heard of what it could be with a Russound cav6.6?

I just placed my speaker wiring from the zone that was having problems into another zone to see what would happen. The speakers with the wiring going into that zone still had problems with sound. It was not the amp to that zone. Can speaker wire go bad? I have never heard of such a thing!!!It is a high quality wiring.

Lots of things could have damaged the wire. Someone putting a nail in the wall for a picture. Water leaking from somewhere (and into a nick in the wire's insulation). Something settling and crushing the wire enough to break some of it. Rodents or other vermin chewing on it. Then there's corrosion, unlikely in most residential settings but possible if the wire was poorly manufactured. But it may also be the connections at either end.

Okay, get this. The room in question was a room we never really listened to with any kind of volume much above 16 or 20. The other day was the first time really that we listened to music above that volume and that is when we heard the problem. That is why I was trying to find out what had happened. I have been looking for answers but nobody seemed to have any that made any sense. I have been scrambling for answers to the point of even thinking of replacing the wire which would have been a major undertaking. After checking the speakers wiring from the Cav to make sure all was correct I went down to the Cav and all the wiring on the back of the Cav was the same. I then just for the fun of it decided to move the positive and the negative around and just switch them. You would not believe it. The problem went away. The wiring on the Cav must be screwed up on that zone. It now works after I put the wires in the wrong places.

Um, audio isn't going to make any difference (to most ears) if you swap the polarity of the speaker connections. What you may have done is to improve a bad connection by disconnecting and reconnecting it. I' venture a guess that if you swapped those wires back to their original polarity things would work just as they do now.

When you say 'went down to the CAV' I take it you mean in the basement? If there's any moisture down there it's entirely possible there's corrosion involved. Generally you want to avoid having any electronic gear set up in a high moisture situation. A dehumidifier may be necessary. I once had a server running a basement and in three months time down there it started acting very flaky. When I opened it up and checked there was a fine amount of corrosion on all sorts of surfaces, including the slots for the RAM.

Well, no by switching the wires back to the original it went back to sounding terrible at a louder volume.
As for humid, nope to that also. I have a theater, bedroom, office, candy room and all sorts of neat stuff down there. No moisture problem down there. There is no corrosion on any of the connections.
I don't know what to tell you but changing the connections does make a difference even if it is not supposed to.
