G, I assume that there wasn't any extra noise in the room when you ran the calibration. Apparently there was very little low bass being measured by the microphone in its position, even from the M50s. I wonder if the mike(and your listening position)was near the center of the room in a location where there was a bass null which the mike was reading. It might be interesting to move the mike 3-4' closer to the wall behind and re-run the calibration to see if the results are different. In any case, those crossover settings should be manually adjusted as the manual describes(leave the other EZSet calibration settings alone). Since two of the settings available are 80Hz and 100Hz, the M50s should probably be set at 80Hz and the other speakers at 100Hz.
