I've been reading more on implementing room EQ with my DIY M2's and was wondering if anybody has used the Harman Target Curve as a reference?

Sean Olive wrote an article about different Room Correction products here back in 2009 that I recently read and it gives two examples where room eq either didn't help or sounded worse than no eq.

Greg Timbers as also noted room correction here, I'm guessing he assisted on the above curve. He mentioned not to mess around with eq above 400hz unless you know about the loudspeaker directivity behavior. Measurements on each side of the two listening positions (around 3.5 feet or 1 meter) I have in my listening room resulted in very good directivity with the M2 Waveguide.
