AB  - This paper presents a system for adapting a loudspeaker to its position and to the acoustic properties of the listening room: the ABC room adaptation system. Adaptive Bass Control (ABC) measures the acoustic radiation resistance seen by the bass drive unit and calculates a digital filter, which is inserted in the signal path before the power amplifier. The radiation resistance is calculated from measurements of sound pressures at two different positions in front of the bass drive unit. The measured radiation resistance is compared to sound pressure measurements at different listening positions. The ABC system has been found to provide a room adaptation, which is globally valid throughout the listening room, i.e. all listening positions benefit from this system.
