DESCRIPTION
The KF850 Series has been the touring system standard for well
over ten years, being acceptable in more technical riders than any
other loudspeaker. The KF850z incorporates a number of advances
in loudspeaker technology and performance developed over that
time by EAW Engineers. The result is a KF850 with higher impact
and fidelity than ever before.
Legendary KF850 performance is enhanced with a neodymium,
Orbital Magnet Array™ HF driver offering increased surface area for
better cooling, and higher reliability. A new HF horn extends HF
response and fidelity while minimizing throat distortion. The critical MF
subsystem is based on EAW's Radial Phase Plug™ design used in
the KF650, KF750, and KF760. An optional user-installed, passive
MF/HF crossover kit allows more economical, bi-amplified operation.
The KF850z's advanced performance will not be sonically
compatible with existing KF850E inventories. To facilitate
integration, kits are available to upgrade them to the KF850z. The
KF850z's enclosure and rigging hardware are fully compatible with
the KF850E Series. However, the "z" enclosures incorporate a
stacking pad on top that mates with a recess in the bottoms. KF850z
DSP processor settings are available online for EAW's MX8750 as
well a select group of other popular touring processors.
KF850 Series applications continue to include: concert tours,
corporate events, large theaters, stadiums, cathedrals, large live
music clubs. Six year warranty.
1 To achieve specified performance, the listed external signal processing with EAW-provided settings is required.
2 For recommendations to select power amplifier size refer to : "HOW MUCH AMPLIFIER POWER DO I NEED?" on the EAW web site.
EAW products are continually improved. All specifications are therefore subject to change without notice.
