Granite Slabs


I've seen a few systems here that used granite slabs under speakers. Where would one find these cut slabs to size and how thick would the granite need to be to support 225lb speaker? Looking for 2 pieces cut about 20x17x1-2", any help would be great.

I do not have any direct experience with IsoAcoustic GAIA feet for speakers but have read a number of accounts of them. They are a tweak and will improve the same parameters the Townshend podiums, more focused bass, better image focus and improved midrange. But the podium are a much bigger improvement... more like a complete sonic upgrade versus a tweak. 

All good information! I'm still not sure about price vs gain on some of these platforms & footers. I figured I try a remnant of granite first and see what happens if anything. My Andra II speakers have poured granite in them and weigh about 215lbs so I'm not sure they are even vibrating.

@sidog1460 Yeah I've looked at his products and wondered about them. I wanted some of is Fatboy disc to play with.

@sqitis  For testing, you could use a 24" paving slab for little money. Paint it black. Stick it in the yard if it doesn't work out.
