Rel S/510 Subwoofer with Silver Cable

Further Information: 

This Rel S/510 is a great subwoofer, but a significant change in system renders it redundant for me. I have bought an active speaker system which includes its own subwoofer. 
 

The Rel blended seamlessly with my WLM Diva monitors and a 300b amp. I used it to fill in the bottom octave, and it also enhanced soundstage. The bass sounded as if it came from the Divas rather than a separate sub. 
 

If you want to rattle the windows it will also do that, but I have kept my glass in tact. 
 

Includes a silver speakon cable for high level connection made for me by Bill. 
 

There is some cosmetic damage at the front left and rear left corners from the previous owner. No impact on performance. 
 

includes grill which appears never to have used, I took it out the plastic for this photo. 
 

I do not have the original box.
