KillZone Posted August 26, 2020 Share Posted August 26, 2020 One of my duel subs is not performing,, there is very little movement from the woofer, and the sub switches on when it receives a signal, I removed the amp and checked for scorching, none all connections good, checked cable to AVR all good but if I swap over sub cables I don't get the humm while connecting the sub I do on the other sub, I have contacted Klipsch, very slow customer service still no response since the 17 th of August. Any ideas would be appreciated. Quote Link to comment Share on other sites More sharing options...

Amstaff Posted August 26, 2020 Share Posted August 26, 2020 Sounds like a bad amp - not unusual with Klipsch's powered subs. How old? Under warranty? If not - buy another brand. Quote Link to comment Share on other sites More sharing options...
nickyboy6100 Posted August 30, 2020 Share Posted August 30, 2020 Klipsch amp failure seems to be very high on their subwoofers. Why do they continue using poor quality amplifiers if they know this is an issue. I would be very reluctant to buy a powered subwoofer from Klipsch.

I don't think they do still use these poor quality amps. The SPL-150 have an entirely different plate amp in them, and I haven't heard anyone complaining about amp issues with these. I have one, but it's only a few months old, so time will tell... 🙂 Quote Link to comment Share on other sites More sharing options...

No i haven't. I hope that they have fixed them though. Quote Link to comment Share on other sites More sharing options...
