yeah, the sizes are 10, 12, 14, and 16..but i had my toms shaved off just a little bit. so my rack toms are actually about a 3rd of an inch shallower than the standard tom sizes of 10x8 and 12x9. it allows me to position my toms where it's comfortable for me. i had a session last week and only used one rack and one floor. they sounded amazing. resonanted and carried out full tone like a drum is supposed to. the bass is so nice. they just sound like they have a natural EQ. (i'm using aquarian drumheads all around)..
