MEASUREMENTS

I used DRA Labs’ MLSSA system and a calibrated DPA 4006 microphone to measure the Manger p1’s frequency response in the farfield, and an Earthworks QTC-40 mike for the nearfield responses.

When I picked up the Manger speakers from Herb Reichert, he told me that he suspected that the p1’s sensitivity was lower than the specified 89dB/W/m. My estimate was indeed lower, at 85.6dB/2.83V/m. Manger specifies the impedance as 4 ohms,
