Example D:
This is a near-ideal case, and the recommendation is to do nothing. Your system will be
fine as it is.
Example E:
Two interference response dips; no peaks due to room modes. This pattern may be seen
in small spaces where two different delay paths are evident, such as from the floor and a
wall. The absence of a mode peak indicates that the listener is located toward the center
of the room. Slight repositioning of both listener and loudspeaker may change the situa-
tion markedly. Otherwise, no equalization is required.
Example F:
Two LF peaks. In general, you should equalize the peak that has the greater area between
the curve and baseline. You may wish to engage the boundary compensation to lower the
level below 150 Hz, and then repeat the RMC measurement process.
