Bowers and Wilkins DS-3 Brochure

DS3

For large home theatre installations, choose a pair of rear

speakers that can get you closer to the true surround sound of

the cinema.

The DS3 is a wall-mounted surround speaker that can operate in

what’s called ‘dipole’ mode, to create an authentic all-enveloping

effect of the auditorium in a large space. Or, you may prefer to

switch to conventional ‘monopole’ operation, in which the sound

from side or rear is more precisely located and less diffuse. The

choice depends on the room conditions, the size of the audience

and the kind of material on view.

Whichever mode you select, the sound quality is superlative,

supplied by a 130mm Kevlar® cone bass/midrange, twin

midrange/high frequency units and a Nautilus™ tube-loaded

tweeter.
