KF 737

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.
