Best way to keep REL sub from “hopping around” at high volumes


Hey folks, any “best practices” for keeping my REL sub in one place at high volumes?  It’s on hardwood (and/or tile), no carpet.  Besides using something sticky on the feet — like double sided tape, I can’t think of anything besides a brick on top, lol.    Anything that’s worked for you ?   Of course, only happens at high volumes, it tends to vibrate itself around a bit (nothing crazy),   Ideas?

 

 Thanks, Jim

Build a box, fill it with sand (covered by a lid), paint it black, put it on top of the sub.

Best by far, Townshend Bars. These do far more than prevent hopping around, they actually improve bass, and also greatly reduce bass getting into the floor. Huge improvement.

Second best, Nobsound or other springs. Not as effective as Pods but at least as good if not better than all other options. 

SVS or IsoAcoustic footers should work.  It also sounds like the physical motion of the driver is the best direction create some resonance.  Turn the subwoofer around 90 degrees. :)
