I would not bother putting an extra layer of rubber between the 2 surfaces as the speakers need to be as stable as possible, otherwise I cannot see a problem with this idea..............
I really am in horror of the entire concept.
I am personally quite convinced that speakers need to be rigidly coupled to the floor, by years of practical experience installing speakers and systems in peoples homes. Quite why, I am at a loss to understand, and it does vary from speaker to speaker but it does appear to be important.
I have sold and installed systems where the customer has been dissapointed in a lack of focus and precision of the system in his home compared to the shop and in many cases this has been solved by mounting the speakers more rigidly, usually by driving screws into the floorboards and mounting the speaker spikes on the screw heads. (As was normal practice in the shop)
I can recall an occasion where a customer insisted that I come out and hear how poor his system was sounding, he was a nice bloke so I was happy to do so. The system sounded terrible, a brash, fractured quality overlayed everything but I fixed the problem while the chap was making a cup of tea, about 2-3 minutes.
The speakers had clearly been moved, in fact left and right had been swapped, they were not 'handed' in any way, both speaker/stand combination was identical but the screws in the floor were not, quite. The spikes on the stands were supposed to fit in to the 'crosses' on the screwheads (that were driven into the floorboards) but they were loose and rattling. Swap left and right over, settle the spikes firmly in the screwheads and by the time we were sitting down with our tea the problem was solved.
