Speaker size

These tests allow you to determine the bass handling capability of large analogue speakers and subwoofers. Once set, the digital surround controller will limit the bass level to protect the speakers from potential damage.

This is the last test in the calibration procedure; see To complete the calibration procedure, page 26.
