Had the tiles cut to 12X11". FWIW, the four tiles cost $35, the cutting $20, the Dynamat Extreme Door Kit #10435 $52, and the urethane-based adhesive $17...making a total of $124 for the two x-over platforms. My wife calls me Mr. Excess for good reason. :-)

All 4 of these are the same color, that being white/gray-with brown. The pair lying down is reflecting more light from the ceiling bulbs while the 2 standing are reflecting more daylight. Each of the bare tiles weighs an average of 2195 grams = 4.84 pounds.

I then applied one layer of Dynamat Extreme ('DE'; the thicker of the 2 sizes) to the bottoms of all four.

Each of those now weighs 2371 grams = 5.23 pounds or 176 grams or 0.39 pounds more. I then identified the top two tiles of the four and added another layer of DM to each of the bottoms of the bottom pair of tiles. Those now weigh an average of 2577 grams or 5.68 pounds, adding another 0.45 pounds per tile.

The addition of each layer of DM decreased whatever 'boinginess' each tile had, turning the noise into a lower-level, broader-frequency thump. I'll soon be gluing the tiles together, into pairs composed of, from the bottom, two layers of DM, a tile, one layer of DM, and the top tile. As I wrote earlier, I'll suspend each with three Herbie's Audio Lab small, energy-absorbing, quishly footers called...ahem...Baby Booties. Probably I'll use three per x-over assembly.
