1. Select a new test position: Cue the test track corresponding to the center frequency
of the dip. In the example in Figure 21 you would play Tracks 14 (52Hz) and 18 (40Hz).

. You will see a reading very close to what you had before. Now, slowly
move the RSLM around the area, if possible remaining within about a foot of the
original test point. As you move the RSLM, watch the bar graph. You will observe large
level fluctuations. Find a location for the subwoofer or a test location that raises the
response at these frequencies. You may find it helpful to move the RSLM vertically.
Dips can be oriented in any axis. The position that restores the level to about that of
the adjacent test points is your new test position.
2. Reset the test level: Return to the section “Setting the Subwoofer Test Level” on
page 16. Perform the procedure as described.
3. Repeat the measurements: Now that you are familiar with the measurement
process, you can go much faster by using Tracks 27– 50. These tracks contain all the
test tones necessary for measurement. However, each test is only about three
seconds, and there is no frequency announcement. The first test is 100Hz. Just place
each test mark in order until finished. Connect the dots.
Your second measurement will no longer exhibit the deep response dips. However, the
peak will still be evident. Without the influence of the response dips, the amplitude and
center of the peak may have changed.
4. Interpret the new data: Compare your new data to the examples given in this section
of the manual. Follow the instructions for the example that most closely matches your
new measurement.
