PSB Sub has come back the second time under warranty repairs. The whole driver and inside has now been replaced. (virtually a new sub).It went well for a couple of days. I turned the Home theatre system off and as always leave the subwoofer on. After a 3 to 4 hours the unit started rumbling continously and would not stop. I turned it off at the wall and then turned it on again and after a nother 3-4 hours the problem recourred,
I love my PSB speakers but the sub is going to ahve to go back a third time and I am, getting disillusioned.
can you help
thanks Ian
Had this same problem with a Yamaha sub. Unfortunately it's the amp section in the sub. If they can't fix it in the shop (problem is they don't leave it on long enough for the problem to return), the only option is replacement. I buy exclusively on AmEx cards, because they cover this kind of stuff - an additional 1 year warranty on anything you buy.
SOURCE: No LED light on PSB Alpha Subzero-i and keeps blowing fuses.
Others have had similar problems with the amp on this model. There is probably a circuit design error which causes some components to blow and as far as I've read, fixing it (or replacing the fuse) won't make the problem go away for long. Try contacting PSB or the retailer.
