New floors

[daverclark55@gmail.com]

Recently installed engineered hardwood floors over the old wood floors. Previously we had carpet with a pad (say 5/8" thick) and the spike/cones penetrated that into the old wood floor. The speakers were very stable but never "rock" solid. Now with the new floors and a much thinner rug/pad (say 3/8" thick) and not wanting the spike/cones to damage the new floor, we are using the Vandersteen "cups" under the cones/spike. 

Now not quite as stable, but they work. Am hearing that using a slab of something on top of the carpet/under the speakers for the cups to sit on is the way to go. So marble or granite?  Thickness? Ideas as to where to source it?

Dave, the kinetic force applied to the speaker while playing music is not the same as moving them by hand.  Your good as long as you have the out riggers installed 1/8" short of hitting the floor.  It is important they do not touch unless the speaker is rocked by an earthquake or someone to keep them from toppling.  Granite is used by some who or on top of a floor with lots of movement while walking around.  The sound pressure will excite such a tympanic floor and the granite plinth helps.  When I was there, I don't remember any noticeable floor movement.  If better than 300 lbs. doesn't move the floor your speaker won't either.  RV

Thanks for helping Richard.  Dave, as I said, just come on over and ask the question. Welcome to the forums. Hope this helps you out and that you can enjoy the music even more!  I look forward to seeing more of your posts and pics.
