It might help to post the fs from REW. The slight rolloff of the treble is normal and, according to Wendell Dillar at Magnepan, is actually desirable. He told me that a 1 db per octave drop above 500 hz is actually what they try to achieve.
I suspect some of the other peaks are actually room related. Also very important - check the polarity of the connections. If the bass panels are in opposite polarity, you could get significant cancellation as well as poor imaging. You may want to pull the fuses on the mid and treble and just do a fs on the bass and also do scans on the individual speakers.
