DIY speaker isolation base for a wood floor

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. 

Bass is better on Madonna's Erotica. I can't remember lyrics worth a dang but sounds I do remember. I don't listen to lyrics much anyway. Maybe I will try springs on down the road

Well after talking to Fastenal face to face I have decided to abandon the sprungs for now unless someone can guide me. The rep saud that's a tough spring to find. I need a short fat one for stability. Now way am I going to risk my speakers tipping over
