Yoga blocks for isolation

Yoga blocks would seem to be well suited as isolation devices. . Can't hurt to try.

Actually they don't seem well suited as isolation devices at all.  Maybe you meant to say coupling devices.  Perhaps you might also think hockey pucks, Sorbothane and lead fishing weights are well suited as isolation devices, too. I suspect you might need to investigate the whole mass on a spring concept that's been floating around recently.

Try them under speakers on a suspended plywood floor.  It should be relatively easy to determine to what extent they isolate or couple. I suspect more the former but the proof would be in the pudding.
