Abstract
A loudspeaker includes a plurality of electro-acoustic drivers that are configured to be positioned so that an axis running through an acoustic center of the drivers is one of a substantially straight line, J-shape, reverse J-shape, and C-shape. The loudspeaker also includes at least one sensor to detect a configuration of the plurality of electro-acoustic drivers, and a processing device configured to automatically adjust one or more of an equalization and a gain applied to an audio signal output through the electro-acoustic drivers based on the detected configuration.
