I have the HD Theater SB 3, and they are great speakers, but a month or so ago they started making a very odd sound when powered on.
its difficult to describe, but best i can come up with is a zombie breathing in haha i know very odd?
it happens 100% of the time and only lasts about 1-2 seconds, after that as far as i can tell the speakers are perfect.
Any idea what that sound is and if i can stop it from happening?
Thanks
