^ This was only an experimental run tonight, as I only just ordered a calibrated measurement mic. So I used one of my DPA 4006 with the free-field grid installed, and that's a pretty damn flat mic.

I'm already hearing the mid-bass tubbiness of these old KRK monitors being controlled nicely with this corrected house curve applied, and this is with a completely non-calibrated mic. But the same 4006 capsule is used for pro measurement mics, so I figured the results would at least be informative.
