If you are primarily interested in home cinema you may prefer to extend an existing stereo system by adding a pair of rear surround speakers, for cinema effects and ambient sounds.

For cinema the surround speakers do not take a huge strain, so small units can be used such as in-wall or bookshelf-mounted speakers. For 5.1 or Ambisonic reproduction, the rear speakers should be capable of reproducing the full frequency range, and should ideally be the same as the front speakers.

Our recommended surround system for music and cinema uses five speakers, with the main left and right speakers providing the bass. This gives a very natural sound for music listening, and a precise three-dimensional image combined with good bass performance for cinema.

If you also have a mono subwoofer available you can choose to use this for the cinema presets, to enhance cinema effects without affecting the quality of music from your system (Layout AG). This is a good compromise if your primary interest is music, and you want the benefit of enhanced bass performance for films.

Alternatively, you can choose to use the subwoofer for the Dolby Digital LFE channel; see To select a 5.1 LFE subwoofer,
