Sometimes I feel like I know what I'm doing and others I feel lost. Help me understand my measurements.
I have a new MiniDSP SHD with Klipsch Forte speakers and I'm playing around with DIRAC for the first time.
RED: No DIRAC. One position measurement
Green: DIRAC on. One position measurement
Blue: No DIRAC. Moving microphone measurement
Orange: DIRAC on. Moving microphone measurement
The one position measurements were done with REW frequency sweep measurement tool. The moving microphone measurement was done with REW generator pink noise set to the same output level as the previous test and is the average of ~20 measurements with me moving the microphone in concentric circles from my ears.
Questions:
1. Why is the SPL of the moving mic measurements so much lower? It is a good 20dB lower. It doesn't sound that much lower to my ears.
2. Why does the moving mic measurements show so much more high frequency roll off? I played around a bit with one position measurements in the same general area as my moving measurements and the one position measurements are always higher.
This is just a first pass of DIRAC tuning for me but I'm trying to better understand my results before I try to dial in my desired curve.
