Axiom Home Page Forums General Discussion Technical Questions Subwoofer buz

Hey guys... I just recieved my epic 80/350 and just got done hoooking it up.. everything sounds great except for my sub. There is this low freq. buzz coming from it. The buzzing starts to fade away as a turn the volume down on the back of the amp. But it comes back when its halfway turned up. Its not the ground hum because I had that problem to and i solved it by taking out the screw. Anyone know what the problem maybe? Seems like a simple problem.

Try tightening the screws holding in the woofer. Perhaps something shifted in shipping.

I dont know because when i unplugg the cable it stops. Seems like there is interference somewhere. Ive tried changing different power outlets and it is the same. It makes the noise even when there is not signal going to it.

well, there goes my idea.

i just tried plugging in my old sub and there was no buz at all.

Is the cable from receiver to sub pretty good, ie decently shielded ?

yea.. its a moster thx cable.. i think its the lowest end moster cable but it is decent. But do you think its the cable even though i plugged it into another sub and the problem went away?

Nope, doesn't sound like the cable. Even the low end Monster cables seem to be decently constructed.

There was another thread on here a couple of days ago... turned out to be a ground loop from either cable TV or satellite, not sure.

Can you try disconnecting all the sources and see if you still get the hum when listening to FM ? If no hum then add sources back in (ie reconnect cables to receiver/amp) and see when the hum starts.

Ill try that tomorrow but wouldnt the hum still be there for the other sub too if that was the problem?

hey guys.. i messed around with it for a little and when i unplugg the cable wire from my tv it gets a lot louder. Does this mean its coming from that?
