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.

Me, I need to move mine:

Real Heavy Speakers on 3 Wheels. 3 = more weight per wheel than 4, and 3 is always self-leveling.

Current big box, 3 way, 15" woofer, horn mid, horn tweeter, I am guessing between 150-200lbs ea.

3 wheel caution. I have blocks just above the floor at the rear corners, the edge of the centered 3rd wheel, to prevent tipping, especially as they are tilted back as well. If it tips in any direction, the raised corner blocks then hit the floor, preventing further tip.

tilt: a concealed block at the front above the front 2 wheels tilts the speaker back, both time alignment and altering angle of reflections off the floor and ceiling.

Move to precise listening position, or push out of the way (some or a lot).

I've done the isolation/spike thing, with these, other 120lb speakers, and lighter ones. With enough weight I like wheels.

My JSE Model 2's, 125 lbs each, came with factory wheels.

Tried em, spiked em, no improvement obvious to anyone, so I changed 4 wheels to 3 on them. They had their own time aligned slanted front panel, and I just carefully avoided tipping. Loved them for many years, Son Chris has them now.
