Help with Dunlavy Aletha

Thanks everyone for your input. I discovered the problem I was in countering was wrong placement of listening chair sat it right in an 80 hz null. Moved seat one foot placed speakers 4 ft off front wall and it’s sounding very good. 

Yes, Dunlavy suggested long wall placement, and absorbent room treatment behind the listeners head.

Yes, 2 1/2’ +/- 6” from back of cabinet to wall.
