EAW KF300z User manual

A 3-way full range loudspeaker in a vented trapezoidal enclo-
sure. Includes a 12-in woofer, a horn-loaded 7-in midrange
cone with Radial Phase Plug™, and a 1.4-in exit compression
driver on a 90° x 45° constant directivity horn. The internal
crossover is user-switchable for either passive or bi-amp oper-
ation (with a passive LF/MF crossover). The enclosure has six
fly points, three each top and bottom, plus an integral pole
mount cup. Handles are located for the best balance when
carrying.
The KF300z is one of the smallest, full-range, 3-way loud-
speakers available. It is particularly suited for portable or
installed applications, including band PA, club systems, cor-
porate AV, and theatrical productions. The midrange section
incorporates a 7-in radial phase plug based on EAW’s patent-
ed 10-in Radial Phase Plug™used in other KF Series products.
This design produces a time-coherent midrange wavefront
that is critical to ensuring good vocal articulation. The
appearance of the KF300z is enchanced with a curved gille
that matches other KF300 as well as companion KF600 Series
products. Six year warranty.

EAW products are continually improved. All specifications are therefore subject to change without notice. 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.
