Hi Mark, I finally got around to taking a measurement of my SubMersive1 with REW. I think I did it right but I took it bypassing the QSC30 because I don't know how to work it. Anyway, what do you think it looks like? Does it look correct? Any tips on the QSC would be really appreciated.
PS I took this measurement with the 850's and Submersive going through my MMC-1. I unhooked the speakers and got a similar response. I then changed the crossover freq. to 160Hz and still got a similar dip at 80Hz.......weird.
