The high-Q KF737 (75-degree horizontal dispersion) enhances the ability of the KF730 Series to deliver concert-level output 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, and can also be used on its own in shoe-box style halls to keep sidewall reflections to a minimum. The unique Phase Aligned™ LF design extends horizontal pattern control into the LF and a bi-amplified powering configuration (passive mid/high) reduces total system cost and complexity. The KF737 rigging system is fully compatible with the KF730 full-range module as well as the SB730 subwoofer. 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.
