SPECIFICATIONS KF750F

DESCRIPTION

The KF750F 3-way tri-amplified full range system contains many new EAW technologies that make it a powerful concert touring sound reinforcement tool. Its Acoustic Singularity™ design aligns the three subsystems along a single axis so the KF750 acts as a true point source, greatly reducing temporal smearing of transient events and improving overall clarity and impact.

Since the large mid frequency horn contains both the high and low frequency subsystems, the overall package is just 31-in high. Still, the KF750F provides consistent wideband pattern control in both the vertical and horizontal planes.

The LF subsystem includes two vented 12-in woofers mount- ed in the MF horn’s upper and lower walls. This spaced con- figuration extends vertical directivity well into the LF pass- band to minimize midbass build up below the array.

The large MF horn loads a specially designed 10-in midrange cone whose geometry exactly matches the rear of its phase plug assembly. By developing the driver and phase plug as a single unit, pathlength discontinuities within the MF pass- band have been eliminated without compromising the direc- tional qualities of the source.

The 2-in exit/4-in voice coil HF compression driver is mount- ed on a 35° x 35° constant directivity horn mounted coaxial- ly within the MF horn flare.

The KF750F’s 15°-per-side trapezoidal enclosure features eight 4-position flytracks (four each front and rear) that accept industry-standard flyclips.

APPLICATION

The KF750F is designed to create arrays with optimized cov- erage in both the horizontal and vertical planes to cover audi- ence areas ranging from 200 to 80,000 people.

At just 31-in tall and 190 lb. per module, KF750F arrays are smaller, lighter, more efficient and, therefore, more powerful than those built with other systems. These smaller, lighter arrays are easier to fly, require less truck space and permit more open sight lines to cover any given venue.

The KF750F works with a companion downfill module, the KF755F, to provide full range nearfield coverage below the array. The KF750F’s smooth power response produces remark- ably even SPL levels throughout the coverage area, allowing it to be used for nearfield coverage when necessary.

Applications include:
Concert Tours	Performing Arts Centers
Houses of Worship	Theaters
