The Process
After measuring the response of my experimental monitor speaker (wedge) I realized that, although it sounded okay, there was vast room for improvement. That big peak around 3.2kHz alone would probably cause trouble without some remediation. So I began with a measurement of the wedge with no processing.
Using Room EQ Wizard it's possible not only to measure frequency response but to predict the effects of parametric filters on a speaker's response.
The Eminence's Response

Before Correction

Response of the experimental wedge before correction.
Filters

Combined response of the nine filters I applied.
Software Prediction

Combined speaker and filter response predicted by the measurement software.
After Correction
