Best sub isolation?

Interesting concept, thanks for sharing. Sounds like a great way to isolate the TT from foot steps and dancing.🎶👍

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.
