Magnepan DWM - Manual (Page 5)

Magneplanar Bass Panel and the “small” Magneplanar as shown in Fig. 2
below. The left and right ears are equi-distance to the respective speakers. High
frequencies will appear to be up and low frequencies will appear to be down.
Midbass frequencies, if in phase, will appear to be in the middle (and louder).
Depending upon the location of the DWM with respect to the limited
bandwidth Magneplanar, the DWM might be 90 degrees out of phase with the
“small” Magneplanar and changing the phase does not make a noticeable
difference in the loudness of the pink noise peak. It may be necessary to move
the DWM with respect to the Magneplanar to achieve a better acoustical in-
phase condition.
