Quatro Wood best feet

where I can get a pair 2 inch thick black granite with reasonable price in bay area? I think I should still try it as RV advised.

I steered you wrong
service via Factory, parts via your dealer
sorry about that!

Guys, granite usually comes in 1.5" slabs.  Get a set of 3" and put 4 more washers on the rear spike and see how that works out.  Go to any place that sells/makes granite counter tops.  Shouldn't cost more than $300 for the pair. I went 1/2" boarder around the speaker for my size.  Measure them though as the size is a bit different than what's on the site.  

@tomic601 No problem, RV told me just give dealer a call to order. I'm still waiting for my Leica DISTO to arrive. BTW, where I should get test track?
@ctsooner Yeah, RV suggested 2inch thick but it seems 1.5" or 3" is more common, I able to find one 12x18 3" for only 76 online plus 40 shipping online, my local shop ask 180 for one 12x22 2".  

@zensview you can download Vandertones at Vandersteen website
burn a CD or play thru streamer
use caution
i also assume you have the Radio Shack Analog SPL meter ?
