B & W DS8S Surround Speakers
|
Accommodating surround channels in the home usually involves mounting a speaker to the side or to the rear of the listening room. In larger 6- or 7-channel systems, it may even involve both. In order to maximise the quality of each location, the DS8S has been designed to operate as either a monopole or dipole design. For use at the side of a room, the diffuse dipole mode gives a more cinematic feel, yet at the rear of a room, the direct monopole mode gives better directional information.
In monopole mode, the DS8S is a 2-way system, using a Kevlar® cone bass/midrange driver and tube-loaded aluminium dome tweeter mounted on the front of the cabinet. In dipole mode, the front tweeter is switched off and the side firing midrange and tweeter units come into play. The system is then a 3-way, with the front main driver acting only as a bass unit.
Switching between the two modes can be done manually, using a switch on the front of the speaker, or more conveniently by means of a 12V trigger.
