Best sub isolation?

Townshend, but for that sub, I think Nobsound would do just fine. I would try 4 springs to start with, but since the sub is not that heavy, 3 per foot might be fine. I had to put 3 tiny drops of superglue beneath the rubber pads that go under the feet of my subs to keep the pads from migrating.

I had the Iso200 and $24 springs are much better.

boing, Boing, BOING! 24-29.00 usd.. Works great..

Just get the SVS upgraded feet and be done with it… 

I would just get the feet and surely will do so but my floor is "special". After a year of trial and mostly error finally cured my turntable issue. Now my wife can dance through the listening/living room with no problem and never have feedback. Additionally the quality went off the charts. (Hyperbole alert) But the SVS SB 2000 will certainly create its own set of challenges. Springs sound right and Townsend is too pricey for this lowly music lover. So in the shop I go to create a spring loaded sandwich. I thought a bottom board and top board suspended by four springs should do the trick. Any tips on this idea? I like the plastic wrap and form damping insert idea. Sub only weighs around 50 pounds so shouldn't be too cumbersome of a situation. Thanks for everyone's help. I guess the subDude pad is helpful but only in a limited way. Suspended from ceiling on spring platform might work too?
