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.

The diagrams below illustrate several different methods of rigging TQ-445 enclosures. In most cases the lower kelping bracket is used to set the desired downward inclination of the
TQ-445 INSTALLATION HARDWARE
cabinet. When using the T-bar, the enclosure may be rigged either using two points or only a single pick up point. The downward angle will be determined by which attachment hole is chosen on the crossbow. An array of TQ-445 enclosures is easily assembled using the modular FB-58 flybar assembly and fixed length steels as shown.
