Did you post this somewhere else too? Get an answer yet?

If you are talking about the 21.75 x 48 x 30 box with the 20.25 x 7.5 port, 12" long, it looks great.

Just under 14 cuft tuned to ~34 Hz.

You can make that port 16" long and still have 13.4 cuft tuned to 32 Hz if you want lower tuning.

doesn't look like a 12 to me ;)

i was thinking leave the 12 sitting in the box in the hole and duck tape from the bottom of the sub to the bottom of the baffle so the sub doesnt free air. would that work?
