DESCRIPTION

A 3-way full range system in a ven ted trapezoi dal enclosur e .
Includes a 12-in woofer, a horn-loaded 7-in midrange cone
and a 1-in exit compression driver on a 90 x 45 constant
directivity horn. Powering mode is switchable: passive (3­way crossover) or biamplified (passive MF/HF crossover).

APPLICATIONS

The KF300e adapts Virtual Array Technology to a compact
arrayable enclosure . 3-way desi gn dr amatically impr oves the
quality of vocal repr oduction while the con e-driven midr ange
horn extends pattern con tr ol in to th e lower octaves . I t pr o­vides high output, high definition coverage for permanent
or portable applications . Universal suspension har dware fea­tures a flytrack with integral 3/8"-16 mounting/suspension
points. Six year warranty.

Applications include:

Band PA Ballroom Events
Corporate Events Convention Centers
Small HOW’s Live Music Club

TYP BOTH SIDES

The three-way full ran g e lou dspeak er system s shall incorpo­rate 12-in LF transd u cer, a 7-in cone MF transd u cer and a 1­in exit compression driver HF transducer.

The LF driver shall be mounted in a vented enclosure tuned
for optimum low frequency response. The MF driver shall be
loaded into a midrange horn constructed of 3mm birch ply­wood reinforced with high density polyurethane foam. The
MF horn shall incorporate a phase/displacement plug. The
HF driver shall be loaded on constan t directivity horn with a
nominal coverage pattern of 90° (h) x 40° (v). An internal
passive filter network shall provide fourth order acoustical
crossover and system equalization.

System frequency response shall vary no more than ±3 dB
from 70 Hz to 20 kHz measured on axis. In passive mode,
the loudspeaker shall produce a Sound Pressure Level (SPL)
of 99 dB SPL on axis at 1 meter with a power input of 1
Watt, and shall be capable of producing a peak output of
132 SPL on axis at 1 meter. It shall handle 500 Watts of
amplifier power (AES Standard) and shall have a nominal
impedance of 6 Ohms.

In biamped mode , the low frequency secti on produce a Soun d
Pressure Level (SPL) of 99 dB SPL on axis at 1 meter with a
power input of 1 Watt, and shall be capable of producing a
peak output of 132.8 SPL on axis at 1 meter. It shall handle
600 Watts of amplifi er power (AES Stan dard) and shall have
a nominal impedance of 6 Ohms. In addition, the mid/high
section in biamped mode shall produce a Sound Pressure
Level (SPL) of 104 dB SPL on axis at 1 meter with a power
input of 1 Watt, and shall be capable of producing a peak
output of 134.8 SPL on axis at 1 meter. The mid/high sec­tion in biamped mode shall handle 300 Watts of amplifier
power (AES Standard) and shall have a nominal impedance
of 6 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of 15mm thi ckness void-free cr oss-grain­laminated Baltic birch plywood and shall employ extensive
internal bracin g. It shall be finished in black catalyzed poly­urethane . Input connectors shall be dual Neutrik NL4 Speak on
plus one each male and female AP4. The system shall in­clude a switch allowing it to be oper ated in biamp or passive
powering mode . A total o f six 3-position flytracks with in te­gral 3/8"-16 threaded mounting/suspension points (3 each
top and bottom) plus 4x 3/8"-16 threaded mounting/sus­pension points (2 per side) shall be provided. The front of
the loudspeaker shall be covered with a vinyl coated perfo­rated steel grill backed with open cell foam to pr otect against
dust.

The three-way full ran ge loudspeaker shall be th e EAW m odel
KF300e.
