Granite Bases for Vandersteen speakers


I had granite bases made made for my Quatros  on Richards recommendation they weigh 120 lbs 
The bases tightened up the bass mover it down even lower ,focused the midrange and add more depth to the soundstage you can check out the picture in virtual systems

Enjoy the Music

I know Agon member, Ctsooner, got marble bases for his Quatro's. 
Hopefully, he can chime in and tell us if it made a difference.
I went with some maple block bases for my Treo's. I can't say they help or hurt. Well, they don't sound worse.
I need to get John Rutan to my place to set things up when I buy the new Sub 3 subs. Perhaps he can do some magic.

So the speakers are not spiked in to the granite there sit in floor protectors and there is a layer of 1/10th of an inch sorbothane between it and the granite if you put something springs between the speaker and the granite it would be like trying to throw a ball from centerfield to home plate  while standing on a trampoline it doesn't work
Tomic601 i do most of the 7's granite base installs for John there is thin soft layer of material on top of the 7's base and are bolted to the speaker I'm getting about 85 -90 % of the benefit  you will definitely hear 100% the same benefits that I got
I talked to Richard before adding the bases  
Personally I have not tired anything under my Vandersteen 5As those look really nice.
Thanks didn't think about until I heard them on the 7s asked Richard if I could do it to the quatros wouldn't be able to attached to the speaker but could sit them on top
