One more arrangement then it will be time to start a construction thread
Still thinking a 7.1 system - I really wanted the two row look with a riser for the rear seating so I think this will work. The rear surrounds will be in wall speakers. The one seat on the back row gets a little short changed in the corner but I think I can live with that (call it the cheap seat).
Distance from screen to front row seating position is 11' and back row is 15'. I'm not sure where the sub should be placed - should I be looking at placing it between the fronts or in the corner where I have it, somewhere else ?
