GENERAL DESCRIPTION
This 1” professional high quality compression driver features a lightweight diaphragm assembly made with temperature
polyester, attached to an edgewound aluminium ribbon voice coil, providing exceptional acoustic pressure over an
extremely wide frequency range, with smooth and flat response and low harmonic distortion. The coil diaphragm
assembly is easily field replaceable without soldering.
FREQUENCY RESPONSE AND DISTORTION CURVES FREE AIR IMPEDANCE CURVE
Note: on axis frequency response measured coupled to TD250 horn in
anechoic chamber, 1w @ 1m
Notes:
*The power capacity is determined according to AES2-1984 (r2003) standard.
Program power is defined as the transducer's ability to handle normal music
program material.
**Sensitivity was measured at 1 m distance, on axis, with 1 w input, averaged
in the range 1-7 kHz
