Hi Joe,
My personal opinion on room correction is that you need to do what you can with the room first. Room correction isn't a substitute for proper speaker placement, proper sub placement, taming echoes in the room with carpeting, etc. So, while I know that's not your exact question, I cannot emphasize enough how proper placement is to start.
Secondly, I'm personally a big fan of room correction in the appropriate application. I have a Revel B15 sub that had manual eq settings way back 10 years ago. Did it make a difference? YES! However, if I didn't have the sub in an optimal positioning then it didn't work as effectively.
Also, room correction, if not done properly can actually make things worse. So, I would likewise make sure that you follow the proper instructions.
Good luck with what you're doing. I personally love seeing the advancements in room correction as it holds such great promise in helping of us with less than perfect rooms (which is basically all of us :-)
