Hey all, I'm designing my own home theater room for the basement, and up until now, things were moving along smoothly. I am planning to install an ib subwoofer into the side wall, relatively close to the screen. This is where I get stuck. I have come to the conclusion that there is no way I can test for sweet spots as you would a normal subwoofer, as I have to make the wall framing in that area slightly wider and with more support to accommodate the baffle board and to withstand the forces of four AV-15 drivers. By placing subwoofer without testing, am I running a huge risk? If so, how can I make calculations or good estimates on where to place it? Also note that I will be installing a box that will allow me to adjust the phase of the drivers if need be. I will also attach my current plans so someone might be able to make an educated guess. Here are my plans as they stand.
