DESCRIPTION
A 3-way full range system in a vented trapezoidal enclosure.
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 (3-
way crossover) or biamplified (passive MF/HF crossover).
APPLICATIONS
The KF300e adapts Virtual Array Technology to a compact
arrayable enclosure. 3-way design dramatically improves the
quality of vocal reproduction while the cone-driven midrange
horn extends pattern control into the lower octaves. It pro-
vides high output, high definition coverage for permanent
or portable applications. Universal suspension hardware fea-
tures 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

DIMENSIONAL DRAWINGS
DIMENSIONAL DRAWING ARCHITECTURAL SPECIFICATIONS
The three-way full range loudspeaker systems shall incorpo-
rate 12-in LF transducer, a 7-in cone MF transducer and a 1-
in 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 ply-
wood reinforced with high density polyurethane foam. The
MF horn shall incorporate a phase/displacement plug. The
HF driver shall be loaded on constant 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 section 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 132.8 SPL on axis at 1 meter. It shall handle
600 Watts of amplifier power (AES Standard) 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 sec-
tion 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 thickness void-free cross-grain-
laminated Baltic birch plywood and shall employ extensive
internal bracing. It shall be finished in black catalyzed poly-
urethane. Input connectors shall be dual Neutrik NL4 Speakon
plus one each male and female AP4. The system shall in-
clude a switch allowing it to be operated in biamp or passive
powering mode. A total of six 3-position flytracks with inte-
gral 3/8"-16 threaded mounting/suspension points (3 each
top and bottom) plus 4x 3/8"-16 threaded mounting/sus-
pension points (2 per side) shall be provided. The front of
the loudspeaker shall be covered with a vinyl coated perfo-
rated steel grill backed with open cell foam to protect against
dust.
The three-way full range loudspeaker shall be the EAW model
KF300e.
