1. An apparatus for controlling a plurality of speakers to play in a multi-channel audio system, wherein the plurality of speakers are arranged at respective positions within a listening area, the apparatus comprising:
- an amplifier for amplifying multi-channel audio signals to be played over the plurality of speakers;
at least one sensor that senses one of temperature and humidity and being disposed within the listening area proximal to at least one of the plurality of speakers for sensing at least one environmental condition of temperature or humidity and outputting sensed data to a controller; and
a detector disposed in at least one of the plurality of speakers configured for receiving a test signal originating from the controller and for reporting to the controller the test signal received by at least one of plurality of speakers, wherein the controller determines the relative positions within the listening area of the plurality of speakers based on the test signal reported by at least one of the plurality of speakers, andwherein the controller adjusts an electrical characteristic of the multi-channel audio signals to compensate for environmental conditions in response to the sensed data from the sensors and on the determined relative positions of the plurality of speakers in the listening area.
