The DS7 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
