PLD does not affect stage height, but stage height can be manipulated if you have low mounted drivers With my old kickpanels, and you can ask audiolife on here as he heard it several times, I was running a simple passive coincident component set with no EQ and the soundstage was above the dash. The car imaged and staged well with nothing more than properly aimed kickpanels. Probably could have been pretty darn great if I had actually taken the time to really tune it and dial in the install some more. Yes, there are pro's and con's for midbass in doors (if you have time alignment). But my comment was more pointed towards his coaxials in the door (presumably with no time alignment), and the problems associated with running non-midbass drivers in doors (diffraction/reflection from the door panel, different listening axis between left and right drivers, steep off axis of near side driver, etc) that kickpanels would correct and improve upon.
