I attached a picture that shows the dimensions of the room I will be putting the speakers in. The plan is to have a screen on the 15' wall with the speakers in those two corners. The room is a multipurpose room making the other 3 corners not great options for a 18" 7pi lower cab. What are your thoughts on placing the 18" 7pi lower cabs above the 7pi's in the front corners? I would then place a third or fourth 2242 in a bass reflex cab elsewhere to help with mode smoothing.
Also, what kind of output are the 7pi capable of? Right now I am running some JBL 3678 (2226 + 2426/2342 bi radial horn) and a 4645B (2242). I would like to be able to get a similar output.
Last thought, what kind of low end extension will the 2242 be capable of in a 7pi cab? In the 4645B cabs, they have a -3db of 35hz without eq and a -3db of 22hz with eq. I believe the eq is a B6 tuning.
