I've got a similar problem with an 8"XLS (dog it is) which needs a bigger box than my 10"XLS, but the box is existing and so have no room for the port.
I only had 1 B&W flowport so I'm going to build a base with the ducting inside, covered top and bottom. On the pic, the air comes in the red dot and comes out the black dot to a 90mm PVC elbow where I can flare the exit. I still haven't worked out the final length and not sure if it will need 3 rows as drawn or only 2.
Anyone see any problems with this method?

Recomandetion is it would be less than 1/10 of C. Its max 34 m/s.
There is simulations which calculate it. I think I calculate it OK.

P.S. Guessing is the mother of all *******offs.
I wouldn't consider that a very good design for home theatre. The vent will chuff like mad. If you really do want a box that small, you need a PR. The design I mentioned pretty much resolves the issues better IMO. The only downside is size. You could come up with a compromised version that could be 60 - 70L, giving up some extension.
