EAW debuts the KF740 three-way, full range line array loudspeaker, a high-output, extremely lightweight compact speaker module that capitalizes on EAW’s modern engineering and manufacturing technology.

Based on input from key end-users, and engineered by the same Whitinsville, Massachusetts-based design team responsible for EAW’s KF Series, the new KF740 line array has been optimized for the widest possible range of touring and fixed installation applications.

The symmetrical design, large horn and spaced woofers provide exceptional pattern control while EAW Focusing and Resolution software, both exclusive, proprietary technologies, further enhance system performance.

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.

Each KF740 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 160 Hz, 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 seamless coverage, from directly below the array to hundreds of feet in front.

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.
