the speaker should be placed flat down onto the Svelte? what coupler I should use underneath?  Precision Couplers?
Call Peter at Symposium tell him what kind of floors you have he will know as he is the owner and manufacturer. 
You should also go to Vandersteen's website and do the 'ask Richard' pull down.  That's the best place to start since he designed them and knows the answer I promise.
