Granite Under Speakers Over A Wood Floor

I'd recommend trying coins first. It should cost somewhere between $.06 and $2.00, depending on the coin and the amount of spikes. Although, I hear that old Spanish doubloons are eerily transparent and sublimely musical. :-)

Hey VTVU,

You're not having any issues with your set-up, so there's really no problem, but I stumbled across a discussion at audioasylum.com where Bobby from Merlin recommended NOT decoupling Merlin speakers from the floor (which you're doing by placing rubber under the granite). He said that the Merlins are designed to couple to the floor. Like I said, it doesn't sound like an issue in your case, but you can always ask him for info if you're curious (and in the discussion I mention, someone had their VSMs on plywood, over carpetting...not really the same situation).
