B.1 Acoustic specifications
Sensitivity: 4 ohm – 87dB 1W 1m, maximum 102dB 32W 1m
Sound pressure level (SPL) sensitivity is measured as follows:
• Full bandwidth pink noise is applied directly to a low output
impedance amplifier with the output limited to the wattage specified.
Sensitivity: 70/100 Volt – 88dB 1W 1m, maximum 102dB 32W 1m
Sound pressure level (SPL) sensitivity is measured in an anechoic
chamber as follows:
• Full bandwidth pink noise is applied through a Model 32 equalizer
and fed into a power amplifier.
