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.

Springs go lower and are more effective than a sandbox. The sandbox was usurped by springs and air springs twenty years ago. Even Bright Star, the original sandbox, saw the writing on the wall.
For a demonstration of a speaker support which both isolates and damps, watch the Townshend Audio Seismic videos on You Tube.
