Does this enclosure sound right?

[Solid_State13 1]

Something happened when I tried to start the thread, whoops. Anyway, I recently got a elemental designs 11Kv.2 (10" sub) for my dorm stereo, and the sealed box really isn't working very well without cabin gain. First time designing a box, but I came up with a design using WinISD. It would be a 2.1 cu ft box tuned to about 28Hz with 27 sq in of port area (slot). the sub will be powered by a 325 watt BASH plate amp, in case that makes much of a difference.

Does this sound right? any help would be great.
