Discounting the argument that nobody's localisation is good when they realise that a 60Kg speaker is suspended over their head on a weak bracket . . . I posit the following : DWMM has a soundstage of, what ? +/- ( 45 > A > 135 ) (degrees) E : -5 to -15 E: +10 to +25 Better estimates and/or actual figures welcome .... ;-)> But my point is that you need better rendering of elevation because the (primary sources of) sound are so close together in elevation (E). The sound stage (angle/azimuth (A)) is relatively broad. So, logically, first order horizontal and third order vertical (I jest ... !).
