If the goal is to try and capture as much of the room as possible, point the microphone towards the ceiling and
use the 90-degree calibration file. If there are multiple speakers, such as in a multichannel/surround system,
then always use the 90-degree orientation to ensure consistent measurement between speakers.
Bear in mind that in-room measurements do not have an absolute ideal reference in the same way that free-
field measurements do. The preferred response can vary depending on the nature of the speakers and the
room. Therefore, at high frequencies (above 5 kHz) adjustment of EQ or target curve by ear is likely to be
needed anyway.

ROOM MEASUREMENT FOR SUBWOOFERS
For me
asuring subwoofers, the orientation of the microphone or choice of calibration file doesn’t matter. This is
because the two calibration files differ only above a few kHz, due to the high-frequency directionality of the
microphone.
