The headrush 108 is a popular and cheap way to monitor fractal rigs. But it is far from "flat". Flat is relative to a lot of things. This thread aims to tame the worst deviations and make the critter behave a little better.
I picked up a miniDsp UMIC-1 and REW software on the Mac using the FM3 as the interface . And with the headrush on the floor, contour switch off, and surrounded in a heavy slab of foam to minimize the room and floor..
Analyzing the RTA plots hundreds of times revealed some big dips in response that can be corrected somewhat with global eq.
The first plot in Red shows the 108 without eq. The plot in blue shows the corrected response with parametric global eq.... which is limited from the lowest and highest bands being shelving instead of peaking. But it still made a drastic difference removing the blanket and boominess.
And the second pic are the settings on the global eq .
Hope this helps someone. Your mileage, temperature, and humidity may vary

Thanks to @scottp for the attached image with all the parameters in one spot!
