FWIW, I found the XTZ room analyzer pro II very easy to use. It quickly and consistently found a big room mode at 38Hz for which it recommended a -22db correction. I attenuated it down with a McIntosh MQ 107 (not quite all the way to a -22db, which made the sound too thin), and my boomy bass issue immediately disappeared in dramatic fashion. The A/B between the equalizer on and off and the bass issue is incredible.
I haven't tried any other room analyzer software or equipment but foundn the XTZ to be simple and to provide exactly the information I needed, so I thought I'd share my experience.
