Granite Slabs

Thank you for all the responses..I think my wooden floor used to exaggerate the bass a bit..vibration..I will keep the granite slabs but the idea to put smt under the granite is also an option..By the way CRP what will your method change in the sound?/I wounder..

Aram,

I also have wooden floors in my listening room. I have isolated my speakers from the floor using inner tubes. The sound stage is depper and clearer. Music is more coherent and focused, where before it was somewhat blurred. There is less "noise and grunge" - that is, the music appears in a quieter darker back ground. Bass instruments are now tighter and recognizable, where before there was just "a lot of bass".

My guess is that if you place your hand or ear against the floor, you will feel / hear vibration in bass and low mid frequencies. This is bad because the floor is a huge, efficient radiator (hundreds of times the radiating area of your speaker transducers), and it makes a bad sounding "speaker". Also this vibration might find its way to your equipment stand.

After inflating the tube, the floor vibration is almost totally eliminated. The speakers are slightly "tipsy" in a way analogous to a turntable support.

This is a simple and inexpensive tweak. So try it, and tell us what you hear.

Granite and spikes are the way to go for the tightest and cleanest bass and the most stable soundstage to my ears. Greg is right on the spot, as usual! Cheers,
