TECHNICAL SPECIFICATIONS
KF861
DESCRIPTION
A 3-way triamp full range system in a trapezoidal vertically
arrayable enclosure. Includes 2x 15-in woofers (“tuned” for
dipolar directivity), 2x horn-loaded 10-in midrange cones
and 2x 2-in exit compression drivers on separate 90 x 30
constant directivity horns.
APPLICATIONS
The KF861 Virtual Line Array module is engineered for use in
vertical arrays of no less than three and as many as 12 units.
DSP-driven Tuned Dipolar Array effects create outstanding
off-axis rejection to 100 Hz and below. Unique rigging sys-
tem provides a new level of accuracy and repeatability. The
system of choice for televised live events. Six year warranty.
Applications include:
Major Televised Events
Concert Tours
