I'm trying to calibrate my sub with a BFD and a new RS analogue SPL meter but when I load the correction file it seems to work inverted.
Here is what I mean.
The first image is without the .cal file, the second image (with the black line being the calibration) is with the .cal file.
Shouldn't the lower frequencies be higher dB on the graph when the correction file is applied? Because as you can see, the opposite happens.
Also I have the SPL meter set to "FAST" and "C WEIGHTING". Should "Compensate for C Weighting" be turned on or off in REW?
Thanks
Andrew
