malmc02 Posted August 17, 2011 Share Posted August 17, 2011 I just picked up a used Klipsch SW15 powered sub. I already have an SW12, and it moves a decent amount of air when turned to 3. The SW15 is basically the same thing but 15" and bigger amp. (seller will give money back if I necessary) Problem: the SW15 seems to work, but it seems to be only running at about 5% power. (Supposed to do 110dB SPL, but it is not doing much at all, even when turned to 10.) Thoughts on what might be wrong? Quote Link to comment Share on other sites More sharing options...
Ironsave Posted August 17, 2011 Share Posted August 17, 2011 Have you tried using an RCA splitter so you are using both input jacks? I assume you swapped it for the other Klipsch sub? (If you are trying a different receiver; etc; it could be the receiver and not the sub). Good Luck. Quote Link to comment Share on other sites More sharing options...
malmc02 Posted August 17, 2011 Author Share Posted August 17, 2011 Yep, tried both RCA jacks, and tried the speaker wire connections. Same thing. Still have the 12, it works fine wih the same cables and same receiver. Quote Link to comment Share on other sites More sharing options...
Ironsave Posted August 17, 2011 Share Posted August 17, 2011 "Contact the seller" is where I would be going....... (You say he will refund $..... correct?) Welcome to The Forum; BTW!!!!! Quote Link to comment Share on other sites More sharing options...
malmc02 Posted August 17, 2011 Author Share Posted August 17, 2011 Yep, he will give me a refund. I'm bringing it to Midwest Speaker here in MN today to have them look at it. If they can fix it for not much $$, that would be great. If it's hosed I'll return it. Quote Link to comment Share on other sites More sharing options...
