well those dimensions give you 6.5 cubes gross internal.

when you say low what do you mean, 32, 30, 28?

if you go with the 15 you should have room to fit in a huge port and still tune it real low.

3.5 cubes tuned to 30 with a port 16" x 4" (64 sq/in of port) takes a port 46.15" long

dropping to 28 needs a port 54.25" long

so you have the room to do pretty much what ever you want.

what do you want it tuned at?, i can throw something together for you that should work.
