KF737 3-Way Line Array Module

PRODUCT INFORMATION

The high-Q KF737 enhances the ability of the KF730 Series to deliver concert-level output and performance in an exceptionally wide range of applications. It may be used at the top of a KF730 array to project focused energy over long distances. It may also be used on its own in shoe-box style halls where you want to keep sidewall reflections to a minimum. The KF737, along with low-Q KF730 full range loudspeaker and SB730 subwoofer, is an excellent solution for applications such as houses of worship, corporate A/V, theatres, hotel ballrooms, and concert halls. The system is also ideal for supplemental coverage for larger line arrays, such as the KF760 Series. Such uses include audience side fill, stage lip fill, delayed arrays for balconies, and stage/performer coverage.

One large MF/HF horn fills the entire face of the enclosure, better maintaining horizontal pattern control throughout the MF/HF passband. The curved aperture MF loading slots effectively move the MF acoustic original further into the horn than physical space permits. The side-mounted LF drivers provide a forward-firing, figure-8-type pattern. The drivers are spaced so that the LF beamwidth matches the MF through crossover.

A bi-amplified power configuration (passive mid/high) reduces system cost and complexity. Processing for the arrays is intentionally simple and can be greatly enhanced with the EAW UX8800 dual-mode digital processor, which supplies EAW Focusing alignment and driver processing algorithms.

The KF737, like the rest of the KF730 Series, offers very friendly truck-pack dimensions. Its rigging system is fully compatible with the KF730 full-range module as well as the SB730 subwoofer. The versatile rigging design fosters fast construction of arrays ranging from 4 to 18 enclosures. Each KF737 includes six QRP2 Quick Release Pins.

  • High-Q brings longer throw capability to KF730 arrays
  • Nominal horizontal beamwidth of 75 degrees
  • Fits seamlessly within KF730 Series arrays
  • Integral light fly hardware of 6061-T6 structural aluminum
