Measurements in Anechoic Chamber

Upper left: frequency response at 1m.

Upper right: distortion characteristics at 1m, 85 dB. As seen, the response is flat and distortion low.

Lower left: cumulative spectral decay at 25cm: As seen, the active suspension does not delay bass or inflict resonance effects like bass-reflex or closed acoustic suspension enclosures. Servo compared to normal.

Lower right: step-response. As seen the step response is sharp and coherent compared to the response of ordinary active speaker.
