I have owned my Klipsch Synergy Sub 10 for about 3.5 years it rattled and was putting out horrible sound like 2 months after I bought it so i just shut it off for a long time and kind of forgot about it .. then i realized i had a 3 yr warranty plan through best buy .. brought it in to Best Buy and they sent it to Klipsch .. i spoke to the person who repaired it and the entire board was replaced because it was defective... got my sub back and didnt really use it until about 2 weeks ago .. so after using my newly repaired sub for about 10 days i shut it off using the little switch on the back because a roommate was sleeping .. the fuse blew and apparently something was also wrecked in the amplifier because it blows any replacement fuse i try to put in it .. 8 fuses later still cant get it to power on .. called klipsch he said if its blowing fuses instantly like that the amp has something wrong with it .. again !! they said u can get a refurbished amp for 60 bucks by sending urs back to us with a 90 day warranty ... or u can buy a new one for 160 with a 1 yr warranty .. I told him sorry man i dont trust ur amplifiers and im not spending another dime on this sub because it will probably just break a week into use... if u are having these same issues i would recommend just buying a new product rather than wasting more money on repairing the ones u have
They sound great when they are working .. unfortunately the amps break like mad!
