FREQUENCY RESPONSE

Frequency Response and Impedance Curve Distortion Response

Measuring Condition	Input signal: Sine wave of 50 W (1/10 of power handling
Measuring environment: Anechoic chamber	capacity.)
Measurement distance: 1 m on the forward axis
Input signal: 1 W sine wave
Enclosure: 120-liter sealed box. (The impedance
curve has been obtained by measuring
the naked speaker.)
