Rel thump


I have a Rel R-505. I bought it used & it worked fine. Lately it's developed a thumping sound instead of the low bass tones. It's really annoying so I unplugged it. I've checked the settings & switched the polarity. No change.    Any ideas what went wrong. 

Thanks

I was thinking something went bad since I bought it used. Ya never know. I've had it since January.

Fixed it....Just ordered a new Rel S/812.

Thanks

Sub drivers have a limited lifespan in comparison to other drivers. They take a real beating. They can also fail in a number of ways. I keep a spare driver handy.

The lesson is to avoid used subwoofers. If you have to buy used make sure drivers are still available.

Ah-ha, I didn't know that. Yep, lesson learned.

Thank you
