I don't get it. Visual learner, sorry.

Conventional speakers would need enough room behind for the ports to be effective. I've heard a distance equal to the diameter of the port suggested (i.e. a couple inches).

I don't know what your "false wall" looks like, but the In-cabinet M60 is 15.31" deep and has the port ON THE FRONT. Maybe that's an option?

Oh, and get the QS8's. They're wonderful.
