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 have a pair of REL SHO’s and they play seamlessly.  I set them at 40% volume.

 

I would never buy used.  There must be a reason why they sold them.

"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

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.

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
