KF300z/0002675/2 pp
April 2002
Printed in USA
The 3-way full-range loudspeaker shall incorporate a vented
12-in LF transducer, a 7-in horn-loaded cone MF transducer
with Radial Phase Plug
™
, and a 1.4-in exit / 2.5-in diag-
phragm HF compression driver on a constant directivity horn.
The MF/HF horn shall have a nominal beamwidth of 90° (h) x
45° (v).
System frequency response shall vary no more than ±3 dB
from 100 Hz to 20 kHz measured on axis. In passive mode,
the loudspeaker shall produce a sound pressure level (SPL) of
92 dB SPL on axis at 1 meter with a power input of 1 watt,
and shall be capable of producing a peak output of 127 dB
SPL on axis at 1 meter. It shall handle 750 watts of amplifier
power (AES Standard) and shall have a nominal impedance of
4 ohms.
In bi-amped mode, the LF/MF section shall produce a sound
pressure level (SPL) of 92 dB SPL on axis at 1 meter with a
power input of 1 watt, and shall be capable of producing a
peak output of 127 dB SPL on axis at 1 meter. It shall handle
750 watts of amplifier power (AES Standard) and shall have a
nominal impedance of 4 ohms. In addition, the HF section in
bi-amped mode shall produce a sound pressure level (SPL) of
101 dB SPL on axis at 1 meter with a power input of 1 watt,
and shall be capable of producing a peak output of 130 dB
SPL on axis at 1 meter. It shall handle 200 watts of amplifier
power (AES Standard) and shall have a nominal impedance of
8 ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of exterior grade Baltic birch plywood
and shall employ extensive internal bracing. It shall be fin-
ished in wear resistant textured black paint. Input connectors
shall be 2x Neutrik NL4 Speakon. The system shall include a
switch allowing it to be operated in passive or bi-amp pow-
ering mode. A total of six 3-position flytracks with integral
3/8"-16 threaded mounting/suspension points (3 each top
and bottom) shall be provided. The front of the loudspeaker
shall be covered with a powder coated perforated steel grille
backed with open cell foam to protect against dust.
The 3-way full-range loudspeaker shall be the EAW model
KF300z.
