Impedance A constant current circuit was used to measure the impedance. Frequency response The frequency response
shown was obtained by feeding a swept sine wave through the system in a half space environment. The position of the
microphone was vertically on-axis at a distance of 2 metres, then scaled to represent 1 metre. 2nd & 3rd Harmonic Distortion
Distortion measurements were obtained using an Audio Precision harmonic distortion analysis system and comply with
AES recommendations for enclosure measurement (AES paper ANSI S4-26-1984). Data Conversion All graphs were digitally
generated using the APEX custom software system, designed to translate data derived from Audio Precision ‘System
One’ test equipment into AutoCAD™. This program enables graphical information to be plotted to a high degree of accuracy.

allows for a wide range of adjustment angles in both horizontal and vertical planes.
The cabinet can also be installed using CB-10 ceiling brackets and WB-10 wall brackets, as
well as with OmniMount™ wall and ceiling brackets.
A threaded insert is also provided on the bottom of the cabinet, and this can be used to
attach the loudspeaker to standard 3/8” microphone stand fittings.

160 watts program. Sensitivity, measured with 1 watt input at 1 metre distance on axis, mean
averaged over stated bandwidth shall be 90dB. Maximum SPL (peak) measured with music
program input at stated amplifier power shall be 115dB. Dimensions: 300mm x 164mm x
158mm (11.8” x 6.5” x 6.2”). Net weight: 3.5kg (7.7lbs). The loudspeaker system shall be the
