Below is an older pic of my garage theater. I currently have a sonotube sub with a single Tempest. Due to some redesigns in the theater the big tube must go. The room is 9' x 16' by 7' high. You can see more of the room by clicking on the link below. I don't have room to have a 20"+ manifold sticking outside the theater so a wall mount design will work best. I was thinking about using the existing hole where the AC unit is and mount the Tempests there. Most say 2 is minimum so I'll order up a second, if this will work. So, can some of you IB pros chime in here and give this IB newbie some tips on mounting, locations, wiring up the Tempests...etc? What kind of sound will fill the garage by having the Tempests exposed in there? I've been to the Cult room but not many of my questions related to my specific concerns are answered there.
