Subwoofer


I noticed my subwoofer with my home theatre setup was not working.  When plugged in, makes a distorted on and off sound.  Replaced it with another sub and worked fine for about a month.  Then it stopped working too.  Has a bad distortion sound almost like its blown.  Any ideas of what this could be.  I hate to buy another sub if it has something to do with the home theater receiver I am using.

Based on such sketchy information I can only say ditch the HT receiver, and all the other HT stuff, start over with a stereo integrated amp.

could be a bad connection.  If I were you I'd get some contact cleaner and spray it on both ends of the interconnect connecting the receiver to the sub.
