This is the room response of my DIY 2-way speakers with 12-inch Faital pro woofers, JBL waveguide on Celestion compression drivers and powered by Hypex FA123 modules (
pics). Currently, I stopped advancing with the prototypes and decided to just listen and enjoy them for a while in their current state. I applied some room correction to the raw response with the in-build Hypex 8-band PEQ stage.
Measurements were conducted as moving mic measurements with pink noise and 1/48th RTA in REW, of course. The first picture shows individual channels pre-EQ and the corrected stereo sum (calculated, not recorded) of both channels post-EQ. Smoothed to 1/12 octave. PEQs where applied between 48-440 Hertz only.
The second image shows equalized response of individual channels:
Note this is a constant directivity design and the speaker has matched narrow directivity between something like 500-15000 Hertz, hence little room curve. It sounds right, though. Quasi-anaechoic response and other measurements are collected in my "I ask for help" thread over at
diyaudio.com, here is the on-axis without room (gated to 4.5 ms):
I am happy to have learned about MMM, because averaging individual sweeps was kind of tricky. It has to be noted though that, due MMM not recording phase and impulse the summed response is RMS and not Vector so without phase and there might be more problems between 200-500 Hertz in my room when speaker response is summed correctly. Will dig into this another time.
