The KF850 Series has been the touring system standard for well
over ten years, being acceptable in more technical riders than
any other loudspeaker. Its longevity is attested to by the fact
that with over 10,000 units already out in the field, several
hundred are still sold every year. Knowing customers still employ
this workhorse every day, EAW engineers decided to modernize
the touring classic with a significant performance upgrade featuring
the latest proprietary technology and contemporary components.
The result, the KF850z, has 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 LF
section horn-loads the 15 inch woofer first used in the KF650z,
improving its dynamic response even further.
Two KF850z models are offered: the KF850zF and KF850zR. Flown
applications may use the "F" version, which features
rigging hardware identical to the earlier KF850EF. In many
applications KF850s are ground stacked in theaters, clubs,
and outdoor festivals, or are used for side fill/drum monitoring.
To address these applications, we offer a new version without
flytrack - the KF850zR - which considerably reduces the weight
of the enclosure by 41 lb/18.6 kg, or 22%. Both enclosures
incorporate a stacking pad on top that mates with a recess
in the bottoms.
The SB850zR is a significant update of the SB850R, and is
an excellent sub-bass complement to the KF850z full-range
loudspeakers. A deeper enclosure was designed to allow use
of the same driver used in the legendary SB1000. This significantly
enhances the SB850zR performance, providing the same high
impact and low frequency response of the SB1000 but in an
enclosure footprint matched to the KF850z. The SB850zR enclosure
also incorporate a stacking pad on top and recess on the bottom
which facilitates stacking it with the KF850z or additional
subwoofers.
DSP processor settings will soon be available online for
EAW's MX8750 as well a select group of other popular touring
processors. The full range KF850z and SB850z subwoofer are
appropriate whenever an application calls for loudspeakers
capable of ultra-high output and tight pattern control. They
are ideal as a main reinforcement system for outdoor festivals,
theatres, clubs, side fill/drum fill monitoring on large stages,
and as a dedicated side fill element in ground-stacked KF760
rigs.

Caster Pallets - see
picture
A Baltic birch caster pallet is available for the KF850zF,
KF850zR, and SB850zR loudspeakers. The pallet has four heavy-duty
wheels and a magnet block assembly, which affixes to metal
discs mounted in the bottom recess of each enclosure. Cutaways
along the side of the pallet leave the KF850zF fly track exposed,
so that it may be transported with fly clips attached. The
cutaways also provide wheel clearance allowing the pallets
to be easily stacked when not in use.
DIY Caster Pallets - see
picture
EAW also offers "z" version caster pallets in kit form.
Four pallets may be constructed with the kit. It includes
wheels, magnet blocks, magnets, and all necessary mounting
hardware. The user need only supply wood to cut out the
pallet platform, paint, a few tools, and some shop time.
An easy-to-use template is included to aid in cutting the
wood platform and drilling the appropriate holes.
Bi-amp Kit - see
picture
A passive MF/HF crossover was developed so that users can
deploy the traditionally tri-amplified KF850z's in a cost-saving
bi-amplified mode, thereby requiring less amplifier channels
and reducing weight in the truck. This low cost kit is user-installed,
and includes a passive mid/high crossover, stickers for
the input panel which depict the new input jack pin-out
configuration, and installation instructions. Installation
can be completed in about 15 minutes. The bi-amp crossover
kit can only be used on a factory-built KF850z. It cannot
be used on a KF850 originally manufactured as an "E" series
and later upgraded to a KF850z.
"z" Upgrade Kit - see
picture
Owners of KF850EF loudspeakers can upgrade their inventory
to KF850z performance via one of two upgrade kits. The two
kits are identical except for the input configuration: one
includes Neutrik NL8 connectors, while the other includes
AP6 connectors. Each kit contains all the new "z" components:
a 15 inch LF woofer, an MF sub-assembly with 10 inch cone
and Radial Phase PlugT, an HF compression driver with horn
and mounting brackets, an input panel and wiring harness,
and a passive HF network. Detailed instructions guide users
through the step-by-step installation process.
Fly Clips - Fly
clip with hook / Fly
clip with ring
Two fly clip fittings are available for suspending the KF850zF
loudspeaker: a version with a steel ring and another with
a steel hook. In a typical application, two KF850zF cabs
would be suspended from one another by affixing a fly clip/hook
to the bottom-most enclosure and hooking it to a fly clip/ring
on the upper-most enclosure. Alternatively, two fly clips
with rings may be coupled with a user-supplied shackle.
