DESCRIPTION

A 3-way full range system in a ven ted trapezoi dal enclosur e .
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
compression driver m ounted coaxially in the wave guid e cavity
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 dra­matically improves the quality of vocal reproduction while
its cone-driven midrange horn and horn loaded woofer ex­tend pattern control into the lower octaves. Universal sus­pension hardware (flytrack with integral 3/8"-16 mounting
point) supports permanen t or portable applications . Six year
warranty .

Applications include:

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

VIEW A-A

The three-way full ran g e lou dspeak er system s shall incorpo­rate a 15-in LF transd ucer, a 10-in cone MF tran sdu cer 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 ply­wood reinforced with high density polyurethane foam. The
MF horn shall incorporate a phase/displacement plug. The
HF driver shall be mounted coaxi ally within th e woo fer cav­ity and shall be loaded on a constan t directivity h orn 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 n etwork shall provide fourth
order acoustical crossover between the mid and high fre­quency 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 Ohm s. The LF section shall produce a Sound
Pressure Level (SPL) of 100 dB SPL on axis at 1 m eter 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 amplifi er power (AES Standard) an d 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 mi drange fr equency section in triamped m ode
shall produce a Soun d Pressure Level (SPL) o f 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 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 one each male and fe­male AP4 plus one each male and female AP6. The system
shall include a switch allowin g 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 provid ed. Th e fr ont o f th e loudspeak er
shall be covered with a vinyl coated perforated steel grill
backed with open cell foam to protect against dust.

The three-way full ran ge loudspeaker shall be th e EAW m odel
KF650e.
