DESCRIPTION
PERFORMANCE
FEATURES
APPLICATION
• VA™ MF/HF downfill system
• 10-in MF on asymmetrical horn
• 2x 2-in exit HF on separate horns with separate
coverage areas
• Frequency shading integrates HF horns when
powered together
• Power HF horns separately for maximum control
• For portable use only
A complex 2-way mid/high system in a multi-baffle trape-
zoidal enclosure designed for down fill from a flown EAW
Stadium Array. Includes a horn-loaded 10-in cone (down
angled 10 degrees) and 2x 2-in exit compression drivers on
separate constant directivity horns. The two HF horns (angled
down 10 and 45 degrees) may be powered separately or in
parallel with complex internal passive filter providing fre-
quency shading to integrate the two horns. Powering mode is
switchable: biamplified (HF horns in parallel with internal fil-
ter and powered by a single amp channel) or biamplified (HF
horns powered separately). When in parallel mode, a switch
allows attenuation of the lower (45°) HF horn according to
trim height.
The KF855 is engineered to serve as the downfill loudspeaker
in an EAW concert touring Stadium Array, providing coverage
to the most expensive front row seats. The two HF horns may
be powered separately or in parallel. The system may be
inverted to reach balconies in converted ‘movie palaces’ or
similar venues. Six year warranty.
