The frequency range can be down to 3.15Hz with less than 1% THD+N. Thanks to the professional acoustic design, the cavity resonant frequency is increase to approx. 800Hz to keeps flat response at low frequency range. 3.15Hz~100Hz flatness is 0.3dB even without calibration, above 100Hz need calibration with standard microphone.
