So I won a 50.00 Amazon gift card at work and after holding on to it for months I found something I could buy. I chose the SVS Soundpath Isolation feet. These rubber tipped feet screw right into the bottom of your sub and can support the weight of a SVS PB 13 sub. Since I already have two gramma pads under my SVS NSD 12/2 sub I got these to put under my tiny Def Tech Prosub 1000 that sits on top of my TV that I use as a mid bass module for my center speaker. I gotta say I was skeptical at first but these tiny rubber feet work just like the Gramma Pad. The isolate the sub from whatever it's sitting on, there is no more vibration or movement during bass heavy scenes. The rubber is very thick but pliable as you can still Squeeze it slightly but sturdy enough to be able to support at least 150 pounds I'd say. For those who think the Gramma pad is big and cumbersome these tiny feet might be a solution. Granted I only paid three bucks and change for the tax on these and feel these would be better priced at 29.99 but have to say I do like these and they elevate my sub about an inch so my passive driver on the bottom of the Prosub has more room to breathe.
