amplitude calibration for dbx rta-m smaart 7

But my adam a5x's sound fantastic in the mids and hi-mids so i was basically iritated by the fact that sonarworks doesn't let me do manual corrections on top of what it has done. everything below 500hz was measured quite well because my room has significant room modes down there. So the DBX rta-m should always be used pointer at the cealing? Even when tuning PA's?

In this image, pink is without calibration file, red is with calibration file, both taken from the same location, and the blue is moving the mic a foot away. Above 8 kHz, the spatial variance you will experience in your measurement by moving the microphone four inches is a far bigger factor than the mic's behavior over 8 kHz. However, u u/ThreeSilentFilms is right on the money in that it's really not necessary. If you really want a file, send your mic to Cross-Spectrum Labs and have them produce one. It is also a pin 3 hot mic so it will create the illusion of a polarity reversal in all your measurements that is not really there. It is designed to be aimed 70 - 90° away from the direct sound, so point your mic at the ceiling and try again. The dbx RTA-M is a diffuse field mic and so will show a large on-axis peak if you point it at the source. If you're hearing that big of an audible difference at HF, my guess is you're mistakenly pointing the mic towards the loudspeaker when you measure. I am wiling to bet some operator error is involved here. r/broadcastengineering - Broadcast Engineering.r/projection_mapping - Projection Mapping.
