Martin Logan Abyss Problem

[harold280z]

I have a Martin Logan Abyss sub for my bedroom. This sub has been great for over a year but recently I’ve noticed that the sub was not working properly. I’d get no sound from the sub, at first I would just turn the sub off and turn it back on and problem fixed...great sound. Now I’m getting to me what sounds like feedback from the sub a low humm. I think just maybe I got a wiring problem from my receiver to the sub. Just wanted to know if anyone else has this problem and the correct fix.

I would try to replace your subwoofer cable first.

Any updates?? Did you check the connection to the back of your AVR or see if the sub cable is "pinched" anywhere?
