Hello all,\nWaiting for my UMM6 calibration mic to arrive today. In the mean time I’m trying to figure out what sub(s) to use. Unfortunately all seven subs are of different power levels, ported & sealed, some don’t have LFE, some have stereo RCA & some only have mono, some but not all have in\/out functionality, some have phase and\/or delay dials. \nCan some one help? I can provide any additional details needed. Thank you!
