What do you put underneath floorstanding speakers?

I usually place the floor underneath 'em, keeps them from falling thru to the ground...[smirk]

My speakers are spiked & on top of 18" square 2" thick pads from your local Home Depot spray painted black. Or some store bought granite slabs for the big spender.
When I first did this there was a noticable improvement in sound.

Hey Speedball: 18" square 2" thick pads OF WHAT?

Inquiring minds want to know.

Thanks.

Rlwainwright, Damnit, you beat me to it.

I got hardwoor floors, i spiked my speakers and set them on top of granite slabs which rest on the floor with rubber feet.
Works pretty good for my purposes.

WIth yours i would reccommend putting a house beneath them. Best way to do it. ;)

Spikes sends the energy from the speakers right down in to the floor. A good thing - as it´s helps getting a better grip on the speaker cones. A bad thing if you have a neighbour or someone in an apartment below, as soundwaves will be picked up by the floor and carried a long way via the inner structure of the building.

You need to get rid of the energy from the speakers, but not send that of a large portion in to the floor. Some kind of soft energy-absorbent may do a better job for you. Such as rubber/vibrapod/foam cones etc. There are plenty of fish if you are willing to try such an solution. See Audiogon for ex.
