Soon to be 12" x 14" deep. My new rack tom will be deeper than its diameter. Woot woot. This is a kit I've been waiting to commission the right company to build for a long, long time. Earlier this year Prestigious Percussion earned the nod: Virgin 9 ply Birch shell, aluminum center ring, ironwood hoops, 8 lugs! Being made as I type this. I'm incredibly anxious and am starting to feel like a little kid on Christmas eve.
Main racks are 9x10 and 10x12. I have a 5x6 and an 8x8 that I still have from back when I played huge kits. My 12x14 is only a rack tom until I can afford another set of floor tom legs (get the drill, boys).
