The KF730 Series is comprised of a small three-way line array module (KF730) and matching small subwoofer (SB730) that fits seamlessly within array structures. These elements provide extremely high output from an exceptionally compact footprint, making them ideal for a wide range of portable and installed applications, including touring/festivals, corporate A/V, performing arts and theatre venues, larger churches, and live clubs.
The KF730 full-range system, which we've nicknamed SLAM (Small Line Array Module), packs a six-driver, horn-loaded KF Series design into its enclosure. A full-sized mid/high horn fills the entire face of the enclosure, loaded with dual 7-inch MF cones and dual 1-inch-exit HF compression drivers.
By designing the horn mouth to fit the entire face of the compact module, exceptional 110-degree broadband horizontal pattern control throughout the MF/HF passband is attained.
Horizontal pattern control extends into the LF passband as well, courtesy of EAW's proprietary Phase Aligned LF design extends horizontal pattern control into the LF.
EAW engineers determined that if dual 10-inch LF cones were mounted on the sides of a KF730 enclosure that held the MF/HF horn proposed above, driver spacing would extend horizontal pattern control well into the LF range. During development, the look of the LF section did prove a little different, but extensive listening tests backed by measurement proved the theory.
With many features adapted from the KF760 Series , SLAM is simple to use, and arrays can be scaled to cover audiences from 50 to several thousand people. The basic approach to array design is simple: vary the angle between modules to focus or disperse output. A fairly flat arc across a number of modules maximizes line array effects, generating increased output for greater throw distances.

As modules are added beneath to cover the near field, an increasing amount of curvature tempers the output for shorter throw distances. The nearest listeners can be right under the array and still enjoy natural reproduction at a comfortable level while the farthest can be hundreds of feet away and get the same performance.
