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.
