My basement home theater is 18x25 with a 10x12 bar area off this room and an 8’ ceiling. Walls are 2x4 construction with full spray foam floor to ceiling. Walls/ceiling are 5/8 dry wall and floor is ¾ dry core plywood screwed to concrete. I have a Klipsch RF 7II system with the SW-115 15’ sub and moving the sub around the room is not helping.
The system sounds good and the sub moves a lot of air but I don’t get any seat of the pants feel. I don’t know if it’s the solid floor or I have to move a lot more air (more or bigger subs or both). I can put in a double door to the area with the bar to shrink the room some. Would lifting the seating on to a riser and then putting subs on the riser do the trick? Would buying a couple more 15” subs get me there or will I need to move to a different class of subs for the room size?
