DESCRIPTION
A 3-way full range system in a vented trapezoidal enclosure.
Includes a 15-in woofer in a wave guide cavity with ARC™
device, a horn-loaded 10-in midrange cone and a 2-in exit
compressiondrivermounted coaxiallyinthewaveguidecavity
on a 60 x 45 constant directivity horn. Powering mode is
switchable: biamplified (passive MF/HF crossover) or
triamplified.
APPLICATIONS
The KF650e Virtual Array system’s true 3-way design dra-
matically improves the quality of vocal reproduction while
its cone-driven midrange horn and horn loaded woofer ex-
tend pattern control into the lower octaves. Universal sus-
pension hardware (flytrack with integral 3/8"-16 mounting
point) supports permanent or portable applications. Six year
warranty.
Applications include:
Band PA Ballroom Events
Corporate Events Convention Centers
Large HOW’s Live Music Club

DIMENSIONAL DRAWINGS
DIMENSIONAL DRAWING ARCHITECTURAL SPECIFICATIONS
The three-way full range loudspeaker systems shall incorpo-
rate a 15-in LF transducer, a 10-in cone MF transducer and a
2-in exit compression driver HF transducer.
The LF driver shall be mounted in a wave guide cavity for
optimum low frequency directivity. 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 mounted coaxially within the woofer cav-
ity and shall be loaded on a constant directivity horn with a
nominal coverage pattern of 60°(h) x 40°(v). A device to
absorb refracted HF energy shall be installed behind the HF
section. An internal passive filter network shall provide fourth
order acoustical crossover between the mid and high fre-
quency sections in biamped mode and system equalization.
System frequency response shall vary no more than ±3 dB
from 65 Hz to 17 kHz measured on axis. In biamped mode,
the mid/high section shall produce a Sound Pressure Level
(SPL) of 107 dB SPL on axis at 1 meter with a power input of
1 Watt, and shall be capable of producing a peak output of
139 SPL on axis at 1 meter. It shall handle 400 Watts of
amplifier power (AES Standard) and shall have a nominal
impedance of 8 Ohms. The LF section shall produce a Sound
Pressure Level (SPL) of 100 dB SPL on axis at 1 meter with a
power input of 1 Watt, and shall be capable of producing a
peak output of 136 SPL on axis at 1 meter. It shall handle
1000 Watts of amplifier power (AES Standard) and shall have
a nominal impedance of 8 Ohms.
In triamped mode, the low frequency and high frequency
sections shall meet all biamped mode performance criteria.
In addition, the midrange frequency section in triamped mode
shall produce a Sound Pressure Level (SPL) of 107 dB SPL on
axis at 1 meter with a power input of 1 Watt, and shall be
capable of producing a peak output of 139 SPL on axis at 1
meter. It shall handle 400 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 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 one each male and fe-
male AP4 plus one each male and female AP6. The system
shall include a switch allowing it to be operated in biamp or
triamp powering mode. A total of six 3-position flytracks
with integral 3/8"-16 threaded mounting point (3 each top
and bottom) shall be provided. The front of the loudspeaker
shall be covered with a vinyl coated perforated steel grill
backed with open cell foam to protect against dust.
The three-way full range loudspeaker shall be the EAW model
KF650e.
