PERFORMANCE
The KF760 is part of the KF760 Line Array Series. The KF760
Series uses advanced divergence shading where all loud-
speakers are powered at equal level. A full KF760/KF761 array
can provide uniform sound coverage from directly beneath
itself out to hundreds of feet without complex signal pro-
cessing. Vertical coverage for the array is set by varying the
splay of the rear of the enclosures, leaving the fronts tight-
packed. This configuration produces a continuous, coherent
wavefront from the array, projecting extended range, high-
resolution sound over its full coverage area.
Quality construction features include, Baltic birch plywood
enclosures, heavy-duty steel grilles, Neutrik NL8 connectors,
heavy duty bar handles, rear hand-holds, and accessory cast-
er pallets. Six Year Warranty.
This high output touring system is scalable from theaters
under 1,000 seats to stadiums. The KF760 is used as the short
to long throw element of a KF760 Series line array providing
coverage in the range of 70 to 400 feet. The KF761 supple-
ments the KF760s to provide near-field coverage for distances
less than 70 feet. The recommended minimum KF760/KF761
array size is four enclosures. For full performance eight enclo-
sures are recommended. To extend the low frequency
response, KF940 SuperSubs™ make an ideal complement to
the KF760 Series.
Applications include:
Arenas Convention Centers Large Ballrooms
Stadiums Theaters Music Pavilions
Auditoriums Outdoor Events

The tri-amplified, three-way full range loudspeaker system
shall incorporate 2x 12-in LF transducers, 2x 10-in horn-
loaded cone transducers with Radial Phase Plug™ and 2x 2-in
exit/3-in voice coil compression drivers also horn-loaded.
The LF transducers shall each be loaded into a proprietary
bent-horn, with the horn mouths horizontally separated to
provide controlled off-axis cancellations to match the MF
beamwidth through the crossover region. The MF transducers
shall both be coupled into a single large format horn. The HF
transducers shall each be coupled to an HF horn coaxially
mounted with, and extended by, the MF horn. The system
shall have a nominal dispersion pattern of 80° (h) when used
as part of a KF760 line array.
System frequency response shall vary no more than ±3 dB from
80Hz to 16kHz measured on axis. The single loudspeaker’s
subsystems (LF/MF/HF) shall produce Sound Pressure Level
(SPL) of 96/108/113 dB SPL on axis at 1 meter with a power
input of 1 Watt, and shall be capable of producing a peak out-
put of 135/142/144 dB SPL on axis at 1 meter. The eight (8)
enclosure array loudspeaker subsystems (LF/MF/HF) shall pro-
duce SPL of 106/125/117 dB SPl on axis at 1 meter with a
power of 1 Watt, and shall be capable of a peak output of
154/169/156 dB SPL on axis at 1 meter. The subsystems
(LF/MF/HF) shall handle 2000/800/300 Watts of amplifier
power (continuous) and shall have nominal impedances of 2x
8/8/8 Ohms.
The loudspeaker enclosure shall be trapezoidal in shape. It
shall be constructed of void-free cross-grain-laminated Baltic
birch plywood, and shall employ extensive internal bracing. It
shall be finished in wear-resistant textured black paint. Input
connector shall be a Neutrik NL8 with an additional NL8 pro-
vided for connect through. Proprietary rigging is provided for
arraying. The front of the loudspeaker shall be covered with a
powder coated perforated steel grille.
The tri-amplified, three-way full range loudspeaker system
shall be the EAW model KF760.
