The CCM 80 is a true high performance ceiling-mount speaker. The tweeter has a 1in metal dome tweeter and a treble contour switch to cut or boost the high frequencies. The frame incorporates “Swing Out Dogs” for effortless installation. The tweeter housing pivots for adjustable off-axis treble response.
Architectual and Engineering Specifications
The loudspeaker system shall be of the mono-amped 2-way type comprising of a single flush mountable circular enclosure containing one 8in bass-mid driver with woven glass fibre cone and one adjustable tilt, 1in aluminium dome tweeter.
Performance specifications of a typical production unit shall meet or exceed the following:
Frequency response shall be 40 – 20kHz ± 3dB. 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 40 – 20kHz shall be 90dB.
External dimensions shall be 280mm (11in) diameter x 104mm (4.1in) depth. Total weight shall be 2.2kg (4.8lb).
The loudspeaker system shall be the B&W CCM 80. No other system shall be acceptable unless the above combined
performance are equalled or exceeded.
