Changed my mind, I want to do a middle T-shaped port now. Here are the new specs and diagrams. 3.65cf net per driver, which is within Fi's range of 3-5. Port area is 16.41 in^2 per cf, above the 12-16 recommended by Fi because there are TWO drivers sharing the same port. Modeling with WinISD puts port velocity within the range of the 23-30 m/s I'm seeing with Fi's recommended enclosures, so I think port area OK.

Also, I'm going to be using a Sundown SAZ-3500D, so I'll be running with 3500 watts at least, not 3200 as in the thread title.

Opinions please before I potentially waste a LOT of money on materials? I cannot change the outer dimensions, that is the max I can possibly go, the only thing I can adjust now is the port.
