 Corner loading gives the most sheer output - but generally the least smooth frequency response.
Even with a front loaded driver, bass radiates as a sphere. You're going to get lots of buildup and boom in that little cavity. Opening up the front and sides will negate that effect - but you'll still want to kill that corner as much as possible while leaving room for the curtain to recess in it.
It's not just about the sub response (which will be much better), it's also about allowing access to the bass absorbtion from all directions in the room to maximize the usefulness of the absorber.

Great info!
OK, by cutting those rectangles out as drawn on the photo above, that will help alleviate the "boom" produced by having the subs loaded into the cavity. And, from your response ("much better") it will also help reflections and absorption. Dang, I have some cutting to do!
So, would it be alright to hang linacoustic in those newly created openings, or should I just fabric cover them? Any advantages or problems to having the linacoustic in those openings as the air flows into the trap? Will the linacoustic negate the effect of the opening at all?
Also, I thought of having a bass trap along the back wall behind the seating along the floor. How helpful would it be to have either an angled 4" thick sheet of spin glass resting on the floor all the way across, or better a chunked triangular wedge all the way across? I figure I have about 18"H x 12"D x 15'L to work with behind my cinema rocker seats.
I'm really hoping to make this room pop--not just aesthetically, but also acoustically!
