One of my SAM™ loudspeaker protection activates before the other, is there something wrong?
This can happen after running GLM calibration, which is completely normal.
Looking at the GLM "measurement" responses, if one of the speaker shows more boost at the low frequencies, it explains the difference.
When calibration is equalized (blue) to achieve flat response (green), it leads to extra head room at low frequencies. So the monitor max SPL is increased because of the gain of the room and therefore it can play louder after equalizing.
