What is it?A pair of large-format, three-way line array modules built around a Kenton Forsythe birch laminate design with a structural foam mid-bass horn.
Details The KF760 is a longer throw module with 80° horizontal dispersion while the shorter throw KF761 offers wider, 110° horizontal dispersion for optimum coverage at closer/front audience regions. Both models feature EAW’s advanced Divergence Shading technology which means that with all speakers powered at equal level, a full KF760/761 array can provide uniform sound coverage from directly beneath itself out to several hundred feet without complex signal processing.
 The design employs a single large horn for the HF and MF subsystem. The KF760 module is also fitted with a parabolic separator (borrowed from the KF910F enclosure) that serves both to combine the vertically-separated HF cells and to delay a portion of the MF drivers’ output, creating a ‘flatter’ wavefront through the mid- and high-frequency ranges. By contrast, the KF761 module incorporates a single HF compression driver with direct-radiating mid-range cones, allowing it to provide ‘concert-level’ output in the nearfield without harshness.
 The KF760 and KF761 share a common LF section which features EAW’s Bent Horn technology said to greatly increase output efficiency. The mouths of the LF horns are vertical rectangular slots at the front of the enclosure on each side. Given the typical length of most KF760 Series arrays, these slots create a true line array for low frequencies, with vertical pattern control to below 100Hz. According to EAW, this prevents excessive LF sound near to and almost under the array while focusing more energy to the longer throws. Signal processing requirements for the arrays have been kept intentionally simple, allowing users to draw upon intuitive system-tuning techniques such as adjusting box-to-box angles or EQ settings to achieve the desired sound quality.
