Introduction

• Sensitivity relative to 20μPa (dB); measurement conditions per items 2 and 3 below.
• Measured axially at 300mm (11.8 inches) from the acoustic port under free-field (anechoic) conditions. In this measurement, the rear port vents into a damped cavity of 160cm³.
• Electrical signal (constant voltage): source impedance < 0.5 ohms; applied voltage: 1.1V RMS.
• Nominal impedance: acoustic conditions per item 2 above; electrical conditions per item 3 above; impedance at 500Hz: 24 ohms; impedance at 1kHz: 24 ohms.
• Total harmonic distortion: acoustic conditions per item 2 above; electrical conditions per item 3 above; maximum distortion of 15% at 500Hz.
• Nominal DC resistance at 20°C: 11.5 ohms.
• Sensitivity frequency range: min, max; 55.0 at 300Hz; 67.0 at 600Hz; 67.0 at 3000Hz; 80.0–90.0 at 3000–4500Hz.
