10.1 ROOM MEASUREMENT SETUP
In Chapters 6 and 8, the speaker, subwoofer and microphone were positioned in order
to minimize the effect of the room on the measured response. Now that the speakers
and subwoofers have an accurate, calibrated response, it is time to measure them
together with the full effect of the room.
Position the speakers and subwoofers (if used) in their normal locations. For the first
measurement, place the microphone at the center of the listening area, at ear height.
Position the microphone horizontally and point it between the speakers.
Set the controls on the subwoofer as when initially measured: disable its low pass filter
(crossover) if possible, or if not, set it to its highest frequency; turn off any equalization
in the sub; and set any phase or invert controls to their neutral positions.
Your initial room measurement may reveal room-related problems that are best
corrected by moving the speakers or subwoofers. We suggest that you initially take a
single room measurement and examine it (pages 89 and 90) to establish whether better
results would be obtained with the speakers or subwoofers in a different location.
