The Bowers & Wilkins DS7 White is specifically designed as an on-wall surround speaker for multi-channel audio and home theatre installations.

Surround speakers generally fall into two main types – those that one might describe as 'normal' speakers - so-called monopoles, where the sound comes from a set of drive units mounted on the front of the enclosure - and those that give a more diffuse sound field, such as dipoles. Each type has its advantages.

Most multi-channel music is monitored using monopole surround speakers, whatever the multi-channel recording format. This enables better location of side and rear images, although the formation of such images is never quite as precise as it is between the front speakers.

Most films are originally balanced for cinemas, where a large number of speakers spread around the auditorium are used to create a surround sound field that gives an all-enveloping effect. Dipoles are better at recreating this type
