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.

I know an engineer and he has restaurant clients that have him calculate how often that they need to tighten the screws on a ceiling mounted beer mug holder that you typically see in a bar.

The reason for this is primarily vibrations from vehicle traffic. If the screws aren't periodically tightened, then the beer mug rack will eventually come crashing down. Based on this example, I'd say vibration issues is a real thing.

I guess this engineer doesn't believe in lockwashers.
Thanks Georgehifi! The sorbethane came in today from the eBay seller you showed me. Playing the first couple of songs of the Chicago CD I had listened to last. It sounds wonderful. Maybe placebo but I will know later tonight. I got some more springs but not wide enough and too narrow. I'm still going to try the spring method as Geoff likes some day. Right now things are sounding good!
Something is going on here. I replayed Boz Scaggs Low Down and Lido Shuffle and his voice was strident on certain passages before. It is definitely much smoother and not shrill. I will have to listen more to make sure the sorbathane is not smearing or making the bass mushy. Positive first impressions here. Spin baby spin
Ok the sorbethane is toning some things down. On The DBs  Long Train Running the 2nd ryhthm guitar is not as prevelant but sweeter. No a bad thing. I do have to listen harder to hear it. Unless the power coming into my house right now has been filtered by the audio gods, I'm hearing a positive difference. I can see why some songs people might say it takes away detail and smears But it might be system and listener dependent .But time will tell.
