I sit 11' from the front
5'6" centre from the sides walls.
The seating is a three movie style seating, I am in the middle
My imaginary friends are on the left and right

the rear wall being constructed is 5'6" behind and I am 5'.9" behind where the QS8's will go.

I am now running co-axial cabling for the subs.

two runs up front, two runs to the rear wall and three on each side wall in increments of 6'

So two subs I can pretty well put them anywhere, but I really, really don't want a two ft sub jutted out into the middle of the room.

Anthem MRX520
