CWM DS8
See nothing, hear everything
Room acoustics, programme material and personal preference all influence the choice between dipole and conventional surround 
speakers so the decision is sometimes a compromise. The CWM DS8 puts an end to compromise by providing both options at 
the push of a remote control handset button. The CWM DS8 achieves its versatility by incorporating two midrange and tweeter 
driver arrays with a shared bass driver. In conventional mode the system is configured in 2-way format with a 180mm Kevlar® 
bass/midrange driver and 25mm Nautilus™ tube loaded aluminium dome tweeter. In dipole mode the system is configured in 
dual 3-way format with two separate 80mm Kevlar® midrange and 25mm Nautilus™ tube loaded aluminium dome tweeter arrays 
sharing the same bass driver.

Architectual and Engineering Specifications
The loudspeaker system shall be of the mono-amped 2-way monopole/3-way dipole selectable type comprising of a single flush mountable rec-
tangular enclosure with protruding frontage containing one 7in bass driver with Kevlar cone and one 1in tube loaded aluminium dome tweeter for 
monopole usage and two 3in midrange and two 1in tube loaded aluminium dome tweeters side firing drive units for dipole mode.
Performance specifications of a typical production unit shall meet or exceed the following:
Frequency response shall be 45 – 22kHz in monopole, 45Hz – 15kHz in dipole mode. Nominal impedance shall be 8 Ohm. Total power handling 
shall be 150W continuous into 8 Ohm on unclipped programme. Sensitivity measured with 2.83V at 1-metre distance on axis, mean averaged 
between 45 – 22kHz shall be 88dB.
External dimensions shall be 524mm (20.6in) height x 294mm (11.6in) width x 108mm (4.2in). Total weight shall be 5.7kg (12.5lb).
The loudspeaker system shall be the B&W DS8. No other system shall be acceptable unless the above combined performance are equalled or 
exceeded.
