Abstract

Applies to loudspeakers intended for residential systems and environments. It describes procedures that are specifically designed for loudspeakers which are separate sound system components for either monophonic, two-channel stereophonic or multichannel stereophonic reproduction, they may also be applied to other devices such as complete audio and television receivers with integrated sound.
