Technical Specifications KF650is

APPLICATIONS

The KF650is’ combination of compact size, high output and broad, welldefined coverage pattern make the system a good choice for applica-tions that require even coverage of a wide area with a relatively shortthrow. With optional weatherproofing, the KF650is can also be used aspart 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 LFcone transducer, a 10-in midrange cone transducer and a 2-in com-pression driver mounted to a constant directivity HF horn. The systemshall have frequency response of 70 Hz to 20 kHz ±2.5 dB; axialsensitivity (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 highfrequency 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 diaphragmnot less than 88mm in diameter. An ARCTM device shall be mounted inthe 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 taperedso as to simplify construction of arrays. It shall be finished in blackcatalyzed polyurethane. All external hardware shall be stainless steel orshall be coated to protect against rust and corrosion. The front of thesystem shall be covered with perforated steel grill, coated with vinyl todampen resonance and backed with open cell foam to protect againstdust. Hanging fixture attachment points shall be installed in the topand bottom of the enclosure and mating clips shall be included. Thethree-way full range loudspeaker system shall be the EAW modelKF650isR.
