I redid the measurements, keeping everything constant except for subwoofer delays.
The main speaker is a 3-way active, and single subwoofer.
The chart looks like this:
^ the red one has subwoofer delay of 5ms added in the digital crossover configuration.
I have marked out the various peaks...
Okay, so the vertical axis isn't that important I guess, since the peak is locked to 100%, everything else is scaled/displayed relative to the 100% peak.
Dear all, I would be grateful if someone can shed some light why a step response so called "starting point" or "zero point" can be so far below zero.
Refer to the attached image.
Any feedback would be appreciated. Thank you very much.
Posting here some observations about the CAL settings that could explain the huge SPL offset.

Mic Cal "gear" details (after delete preferences-shutdown-reconfigure, and working properly):
I am not sure how REW got into the "red box" state....
Hello @John Mulcahy @JoinUs
It's okay now. I just did a "delete preferences & shutdown", and then reconfigured REW from scratch. Now it's all good. Imported graphs are at 76dB levels.
Hi John,
I am using 14ea64. Today I imported sweep recording, and the graph is at 125dB level, when it should be at around 76dB level.
Not sure why this is happening. Is it some REW setting that I need to check?
Attached is the MDAT, sweep recording, sweep source.
Hi John,
I found some trouble with the latest build 5_20_14ea47.
When I import sweep recordings, the distortion graph is all greyed out.
It does not happen with 5_20_14ea39.
