Setting Sub Crossover Freq

I second the use of REQ Wizard. My Maggies are rated to about 45HZ, but the in room response according to the room EQ wizard is 65hz. I was running my sub crossed over at 45 and I felt like I had a gap in the low end, this is was prior to running the REQ Wizard and want prompted me to run in in the first place. I bumped my crossover up to 65HZ and all is good now. The optimal setting would be 80hz but the sub was a bit too localized at that setting, this may or may not be an issue with your set up, it just depends on the placement of the sub in your room.

Does the software require much in the way of miking, etc ?

One mic, preferably but not necessarily, calibrated.
