Floorstanders on wood floor, help

The slabs are a good idea, as are Symposium or Audio Resolution or other "draining" shelves. Actually, the shelves over granite slabs may be an awesome combo !

I have granite blocks wqith shelves, for my VMPS monitors, and they do a great job.

I second the big hunk o' rock idea. Even soneting that's 20lbs should help. I would try spikes or cones under a paver slab then compare the speakers on top with spikes and some isolation. I would recomend something other than sorbothane. My experience with wood floors (no carpet) was that bass energy was going directly downward to the floor and then acting like a drum as you describe. So I only worried about verticaly transmited vibrations, and used a platform which I isolated then spiked the speakers into the platform. For isolation I used:

I bought mine cheap from a supply store that sells parts for heating and cooling contractors. I guess they are commonly used under compressors. They are firm enough that you speaker will not move (clean attack), but they stop most vibration from getting to the floor. With a paver stone the absorb the rest you should be set.

Sistrum speaker platforms.

Are you sure its not your amp or other component IYS?

Hi, I used Vermont marble blocks, front & rear, with iso-blocks underneath to isolate from the hardwood floor. I then installed 1/4-20 inserts on my floorstander speakers and used Soler Points. Excellent results and sweet looking too. Regards, Robin
