Four-channel surround system
(Layout M, 2 Surrounds)
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.
Five-channel surround system
(Layout G, 2 Surrounds)
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,
