Ruler-Flat Heresy Midrange and Treble?

John, 

Thanks!

There is no subwoofer. That bass bump is largely a result of the listening position being a foot from the wall, which location emphasizes 40 Hz 6+ dB. The Heresy’s are around two feet from the wall behind them. The Dayton Audio PA310-8 Ohm woofers are at least 2 or 3 dB more sensitive than the original Klipsch K 22 E (Eminence) 11 Ohm woofers - and much more athletic.  When measuring the speakers in the middle of the room from a yard away that bass hump goes away and the tweeters’ response tilts upward significantly. The 3” long by 3” I. D port tube flattens the bass, moving its peak down in frequency. Picture that wide hump moving to the right almost an octave without the port. 
Dean, a lot of it is the room. Especially below 700 Hz.  You both are right; I need to smooth bass response. I listen at moderately low volumes, and do not mind a bit of “loudness” curve. Though the graph shows a lot.
