TECHNICAL SPECIFICATIONS
KF850EF
DESCRIPTION
A 3-way triamplified full range system in a trapezoidal en-
closure. Includes a 15-in woofer in a wave guide cavity with
ARC™ device, a horn-loaded 10-in midrange cone and a 2-in
exit compression driver mounted coaxially in the wave guide
cavity on a 55 x 40 constant directivity horn..
APPLICATIONS
The KF850 Virtual Array loudspeaker is the world touring
standard, accepted in more technical riders than any other
loudspeaker. True 3-way design dramatically improves the
quality of vocal reproduction while the cone-driven midrange
horn and horn-loaded woofer extend pattern control to the
lowest octaves. Effective for large format permanent or por-
table applications. Six year warranty.
Applications include:
Concert Tours
Corporate Events
Large Theaters
Stadiums
Cathedrals
