Free-air room temperature 25°C (unless
otherwise noted). Measurements were made using Audio Precision System 2722 with
Analog Analyzer filter set to 20kHz brickwall filter. All measurements taken with
audio frequency set to 1kHz and device PWM frequency set to 384kHz, 80kHz Class D
Loop Bandwidth, the LC filter used was 10μH / 0.68μF, unless otherwise noted.
