For example, in the figure above the right speaker has been moved up from 31.2 dB to 31.7 dB,
in order to get the overall level of the measurement curves for the left and right speaker to be
visually as close as possible. Note that in this step, you are not adjusting the actual level that you
will hear. Instead, the purpose of moving one speaker measurement is to determine how much it
needs to be moved to get the two measurements to line up, so that the gain in the IO Manager
can be adjusted later by the same amount. In the example above, the right speaker was
increased by (31.7 - 31.2 = ) 0.5 dB.
9. Sum all the measurements and smooth the sum to 100%.
10. Note how the level of the summed response below 150 Hz (or your chosen crossover
frequency) compares to the level above that frequency. Move the subwoofer plot(s) up or down in
order to match these two areas as closely as practical. (Remember that you can use the
Parametric EQ later to reduce any remaining peaks or troughs in the overall response). For
example, you may have to increase the subwoofer(s) by 6 dB.
11. Generate a new sum to show the effect of the change to the subwoofer(s). Remember that to
do this you will have to hide the current sum and show the room measurements before summing,
because the sum function works on the visible plots.
12. If the resulting sum is now as desired, go to the IO Manager (Refer to IO Manager in the
Reference section). Otherwise return to step 10.
