I just simulated a new run from my original un-E'ed measurements... Looks promising. I've also added a hard knee house curve, +6dB at 20Hz. Match the inroom response better than a flat target anyway. The dip down low is location related, I get it ruler flat to 40 in another position, but then the 40-60 area is messed up. I'd rather sacrifice a little down low. It's not like I'm lacking much down there anyway...
