DESCRIPTION

The KF750F 3-way triamplified 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 staccato 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 pat-
tern control in both the vertical and horizontal planes.

The LF subsystem includes two vented 12-in woofers mounted
in the MF horns upper and lower walls as a Dipolar Array™.
This Dipolar Array extends vertical directivity well into the
LF passband 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
passband have been eliminated without compromising the
directional qualities of the source as all previous phase plug
designs have.

The 2-in exit/100mm voice coil HF compression driver is
mounted on a 35 x 35 constant directivity horn mounted
coaxially 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.

APPLICATIONS

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

At just 31-in tall and 190 lb. per module, KF750F arrays will
be smaller, lighter, more efficient and, therefore, more pow-
erful 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. When KF755’s are either not available or not desired,
the KF750F’s smooth power response produces remarkably
even SPL levels throughout the coverage area, allowing it to
be used for nearfield coverage when necessary.

Applications include:

Concert Tours
Performing Arts Centers
Theaters
