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