EAW Launches Compact 3-Way Line Array Speaker

EAW, a manufacturer of audio system solutions, recently debuted the KF740 Three-Way Full Range Line Array Loudspeaker, a high-output, lightweight compact speaker module touted as EAW's next-generation line array.

EAW, a manufacturer of audio system solutions, recently debuted the KF740 Three-Way Full Range Line Array Loudspeaker, a high-output, lightweight compact speaker module touted as EAW's next-generation line array.

Based on input from end-users and engineered by the same Whitinsville, Mass.-based design team responsible for EAW's KF Series, the new KF740 line array system has optimized for the widest possible range of touring and fixed installation applications, according to the company. The symmetrical design, large horn, and spaced woofers provide exceptional pattern control, while exclusive EAW Focusing and EAW Resolution software further enhance system performance.

Company officials say the KF740 is perfect for applications of nearly any size and delivers output resembling the much larger KF760, but has the footprint and weight of the more diminutive KF730.

Like all KF Series loudspeakers, the KF740 delivers premium, high-output, three-way performance, in a package that is extremely compact and easy to set up. Each module contains two HF compression drivers with 2.5-inch voice coils and two 8-inch MF transducers with 3-inch coils, all of which are integrated into a single horn that occupies the entire face of the enclosure. This allows for consistent 90-degree pattern control, even at frequencies down to 160Hz, as the MF frequencies are transitioned to a spaced array of four 10-inch LF transducers with 2.5-inch voice coils. Two of the LF transducers are mounted within the horn, and two are side-mounted, providing as much as 18dB of off-axis rejection.

EAW Focusing, as provided by EAW's UX8800 DSP, easily and precisely transitions from one system subsection to another. Also, all magnet structures within the KF740 utilize neodymium magnets.

A full KF740 array provides coverage from directly below the array to hundreds of feet in front, according to EAW. The vertical output can be tailored to match the requirements of any space by varying the splay at the rear of the enclosures as directed by EAW Resolution software. The resultant configuration repeatedly produces a continuous, coherent wave front of extended-range, high-resolution audio over the entire defined coverage area.

EAW officials say broadly applicable line sources can be constructed solely of KF740 modules. The KF740 can also be integrated above KF730 modules or beneath KF760 modules to extend the reach of the range to any application imaginable.

The KF740 is assembled in the U.S.A. and is constructed for structural integrity, long life, and sonic reproduction, according to the company. The exterior-grade Baltic birch plywood enclosure, wear-resistant textured coating, and powder-coated steel grille work to protect each module. The extruded structural aluminum rigging, precision quick-release rigging pins and Neutrik STX series NL8 connectors are ideal for touring applications.
