Hi guys, Hoping to get your opinions on subwoofer placement for a JL f113 behind an AT screen. I have a 5x6m room adjacent to a 5x2m room. The divider between the two rooms will be the projector screen wall. I have 3 in-wall speakers for LCR. I’ve read mixed opinions on sub placement (in room, bottom of screen, behind the screen) but suppose I want to go behind the screen, how would you construct it? I understand the sub may sound better in different positions and placements but if forced to go behind the screen, what’s optimal?
