EAW is showing the latest addition to its touring and installation series, the KF760 Series Line Array, consisting of the model KF760 and model KF761. It was developed in combination with numerous sound companies such as Mass AV and Maryland Sound..
The KF760 and KF761 are horn-loaded, 3-way loudspeakers used in multiples to create a curved line source. Utilizing the concept of divergence shading, a KF760 Line Array requires minimal signal processing and allows all loudspeakers to be set for equal output levels. The model KF760 is engineered for medium to long throw coverage (>70 feet) while the model KF761 is for short throw coverage (<100 feet). Used together, they can provide uniform SPL, frequency response, and sonic character to the entire audience, from the front row to the furthest seat.
The midrange drivers are coupled to larger horn mouths which provide a critical ingredient for achieving excellent horizontal arrayability. The HF horns are integrated into and extended by the midrange horns for seamless HF coupling between enclosures. In the model KF760, dual 12-in LF drivers load into bent low frequency horns, offering the efficiency needed for its high LF output.
The nominal coverage patterns are appropriately designed for their intended use. The KF760 coverage pattern is 80-degrees (h) x 3-degrees (v) while the KF761 coverage pattern is 100-degrees (h) x 12-degrees (v). Both models offer a usable frequency range of 45 Hz to 16 kHz.
Identical flying and rigging hardware is integral to both KF760 Series . The rigging points are rigid and interconnect at each of the four corners of the enclosures. The rigging system is constructed of heat-treated, structural steel with captive, retractable hinges .
Enclosures are constructed of Baltic birch plywood and polyurethane structural foam, resulting in a very impressive output to weight ratio. The weight of the KF760 is about 190 pounds and the KF761 about 160 pounds. The overall dimensions are the same for the KF760 and KF761, being 14.5-in (h), 45-in (w), and 31-in (d).
