KF720 3-Way Line Array Module

PRODUCT INFORMATION

The KF720 delivers the three-way design, power and fidelity of the KF Series line array systems in an ultra-compact enclosure weighing less than 44 lbs. (19.8 kg). Fully supported by EAW Resolution™ array design and modeling software, KF720 arrays can fill a range of application requirements from small permanent installations to corporate events.

The KF720 features an internal, passive MF/HF crossover filter network to deliver biamplified powering of the three-way system. Dual 6-in LF cone transducers in a sealed enclosure deliver horizontal pattern control via tuned spacing. Dual 6-in MF cone transducers are mounted in a large horn that fills virtually the entire face of the enclosure, maximizing horizontal pattern control as well as driver efficiency. Six 1-in dome tweeter HF transducers share the same horn with the MF transducers; tightly stacked in the center of the enclosure, the six HF transducers leverage beneficial interaction to generate extraordinary output. The three subsystems feature a symmetrical configuration, allowing coherent summation and even response across the nominal 110 degree (h) by 12 degree (v) coverage area.

The KF720 Flybar works on its own or, via an adapter, can attach to an NTS250 dual 15-in subwoofer. The KF720 Flybar also features adjustable footpads on the “top” so that users can invert it and use it to safely ground-stack up to six KF720 modules. The ingenious rigging system allows users to select a range of module-to-module angles, then simply snaps into place, creating a safe, strong connection between modules. In the unlikely event of a module failure, users can quickly and easily remove the module from within the rigging structure and replace it without ever disassembling the array. Six year warranty.
