Seems like it should get the job done well.

It may seem odd that I compared a 15 to a 12 inch, but it was an interesting contrast that the 12's go a little lower, but the kilomax 15 has a sheer advantage in output power when it comes to pressurizing a large room. Rather a large box at 6.7 cu ft, and it would work just as well with flared ports or a slot vent, which could easily be figured into the design.
