DIY speaker isolation base for a wood floor


A definite sonic improvement in tightening up the bass. 
1. Start with 4 aluminum cones. I used some old Mod Squad Tip Toes.
2. 16x16 slab of granite.
3. 1/8 cork.
4. 1/2 inch neoprene rubber.
5. 1/8 cork.
6. Top with another 16x16 slab of granite.
7. Enclosed with a wood cradle to hide the mechanism.
  The granite is from scraps from a shop and was cheap. The added 1/4 inch of neoprene to 1/2 inch thickness did help. Let me hear your thoughts.

For a demonstration of a speaker support which both isolates and damps, watch the Townshend Audio Seismic videos on You Tube.

I always thought you wanted to couple your speakers to the floor (with spikes).      Now it is best to decouple them? 
I think it’s best to couple the stand to the floor and decouple the speaker from stand, correct?

Do you guys feel like isoacoustic isolation stands are good for decoupling speakers from the stand?
