Auto calibration worked pretty well for me...within 1db of using the SPL meter...on the second attempt. I'm not using a subwoofer so perhaps that was an influencing factor. I can't complain about the feature. I thought it worked pretty well for someone who didn't want to get overly technical with setup.
