1)Free Field Response (4π)

2)1W, 1M Free-Field (4π) except MD-L115 and MD-L118, which are groundplane measurements

3)Measured per AES1984

4)AES1984 50 - 500 Hz (LF), 1 - 10 kHz x (HF); Power = V 2 / Zmin

5)Calculated based on sensitivity and continuous power handling capacity

6)Calculated based on sensitivity and 6 dB peak-to-average ratio of signal used for continuous power handling test * AES1984-2, 40 - 400, 2 hours; Power = V 2 / Zmin
