Technical Specifications KF650is
APPLICATIONS
The KF650is’ combination of compact size, high output and broad, well
defined coverage pattern make the system a good choice for applica-
tions that require even coverage of a wide area with a relatively short
throw. With optional weatherproofing, the KF650is can also be used as
part of a permanently installed outdoor system. Available in R (road)
and P (permanent) configurations.

SPECIFICATIONS
The 3-way full range loudspeaker system shall incorporate a 15-in LF
cone transducer, a 10-in midrange cone transducer and a 2-in com-
pression driver mounted to a constant directivity HF horn. The system
shall have frequency response of 70 Hz to 20 kHz
±
2.5 dB; axial
sensitivity (1W@1m) of 102 dB SPL (LF), 107 dB SPL (MF), 107 dB SPL
(HF); 100 hour sine wave power handling of 400 Watts (LF), 150 Watts
(MF), 80 Watts (HF); horizontal coverage of 60
°
between -6 dB points;
vertical coverage of 40
°
between -6 dB points.
The system’s LF driver shall be mounted directly behind the high
frequency horn and shall be loaded into a vented wave guide cavity.
The midrange driver shall be loaded into a constant horizontal cover-
age horn constructed of 3 mm cross-grain-laminated birch hardwood,
reinforced with high-density polyurethane foam incorporating a cen-
ter displacement plug. The HF driver shall utilize a titanium diaphragm
not less than 88mm in diameter. An ARC
TM
device shall be mounted in
the woofer cavity to control reflections of refracted HF energy.
The trapezoidal enclosure shall be constructed of void-free cross-grain-
laminated birch plywood with integral bracing, and shall be tapered
so as to simplify construction of arrays. It shall be finished in black
catalyzed polyurethane. All external hardware shall be stainless steel or
shall be coated to protect against rust and corrosion. The front of the
system shall be covered with perforated steel grill, coated with vinyl to
dampen resonance and backed with open cell foam to protect against
dust. Hanging fixture attachment points shall be installed in the top
and bottom of the enclosure and mating clips shall be included. The
three-way full range loudspeaker system shall be the EAW model
KF650isR.
