SPECIFICATIONS KF755F, Description, Application

DESCRIPTION

The KF755F 3-way tri-amplified full range system is the down- fill companion to the KF750F array module.

Since the large mid frequency horn contains both the high and low frequency subsystems, the overall package is just 31-in high. Still, the KF755F provides consistent wideband pattern control in both the vertical and horizontal planes.

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 as all previous phase plug designs have.

The 2-in exit/4-in voice coil HF compression driver is mounted on an asymmetrical 35° x 35° constant directivity horn mounted coaxially within the MF horn flare. Vertical coverage is 0° to -35°.

The KF755F’s 15°-per-side trapezoidal enclosure features eight 4-position flytracks (four each front and rear) that accept industry-standard flyclips.

APPLICATION

The KF755F provides optimized downfill coverage below flown arrays or, when inverted, provides upfill balcony coverage from ground-stacked arrays when flying arrays are either not allowed or not desired.

At just 31-in tall and under 200 pounds per module, KF700 Series 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 KF755F’s smooth power response produces remark- ably even SPL levels throughout the coverage area, allowing it to be used as a stand-alone system when necessary in applications demanding that coverage pattern.

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