Hi SRoode... I read your posts and saw your graphs using your new equipment, and I'm glad to hear you got good results.
I neglected to mention in my post above that I have an SMS-1 and have flattened the FR in my room. While the bass response was definitely cleaner and more even throughout the bass range, there was no improvement in 'slam' or 'punch' for me.
So, I tried dialing some in around the 60-70hz area (I think it was in that range, it's been a while), with only moderate results.
While the improvement the SMS-1 made was certainly beneficial, I'm not yet at the bass 'place' I want to be, especially since my bud's 'cheapo' Yamaha sub can provide some of the qualities I like by just plopping it down and turning it on...in my place or his!
