Chashas1 :I tried it couple ways with Brass cones( spikes ) and also BDR cones..Didn't like it either way..I had better success with a
piece of Granite directly on the floor under speakers...Much crisper bass and better mids...Hey Maybe it just me I don't know..Haven't really had much luck with Maple..I have read somewhere that Baltic Birch is much better than Straight grain Maple...But as I said I am no expert on the subject and gave up with the Idea of using Maple......Maybe you are onto something with the Birch Plywood..Maybe if you can glue up some Birch Ply layers of it and come up with a 2" thick pieces ..that might work real well..Just a thought though........
