Somewhere Richard Vandersteen posted an excellent article on speaker isolation and he makes a very good point I've made before:
You want to prevent the speaker's ability from moving back and forth. The forces of the drivers push against the cabinet and can cause it to move, which is audible even when there's very little of it.
So, I would stick to IsoAcoustic style of pucks for a subwoofer and nothing more springy.
