Newest box design

I come out with these biweekly! Woo! I this enclosure I will be using 2x IA 187s recieving 200-300 watts RMS apiece, and pretty soon 600 watts apiece. Best response curve I've been able to find is between 27 and 28 hz cubes shared, so that's my aim.

Enclosure is 16.5h X 36w X 18d external (15 X 34.5 X 16.5 internal) or 4.94 cubes BEFORE displacement

Port is 3X15X31 , or 45^2 inches of port 31 inches long (1.009 cubes including internal MDF wall)

Subs displace .18 cubes

That's a grand total of 3.75 cubes internal net volume with a 45^2 port 31 inches long. What tuning would that be? Thanks.

(EDIT: I'd post the diagram, but in the process of posting this I corrected two errors making the pic obsolete..)
