Just here...
Dang i just searched through 30 pages of subscribed threads to find this one and see how it turned out and you quit updating. I'm thinking about making a fiberglass box this summer for my three 12" R's since I can't seem to get the airspace I need out of wood. Did you ever make any actual measurements on the airspace of the t-top holders? Thanks, Drew
