Floorstanders on wood floor, help

TWL said to use Sistrum platforms. I agree and I use Sistrum Platforms under all my audio devices. Robert will have a particular one to take care of your speaker needs. Tom

A bit of a late response but the Aurios/concrete slab system has worked great for me. I have pictures and a description of and easy way to put them togther in "my system"

UPDATE: since the previous post we've upgraded our power amp from a fifteen-year-old SAE A205 to a new c-j MF2500A.

The changes were manifold, huge and bloody (financially anyway). The point of mentioning this here is that this upgrade fixed the problem this thread addressed. The MF2500A controls the woofers while increasing slam *and* improving bass musicality in every way, quite a feat.

Heavy bass passages still vibrate the floor, more than ever, but this now has little or no effect on the music because there is no more uncontrolled bloom from the speakers. The proof is that we now clearly distinguish the primary sound of an instrument from the secondary sound of its hall decay. Importantly, this is true for even the largest and lowest-pitched instruments like bass drum, organ, tuba, etc.

We'll still try the tweaks all you helpful people suggested (because everything matters) but a special "thank you" goes to Cdc for thinking outside the box. He hit the nail on the head.
