KF850EF Cabinet Speakers

...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 is 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.

A 3-way tri-amplified full range system in a trapezoidal enclosure. 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 55deg x 40deg 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 portable applications.

Cabinet Speakers

Speaker cabinets are specially engineered units in which audio equipment such as speakers and their associated hardware are mounted into. These cabinets can be very basic affairs, little more than a wooden case with no additional features other than one port for inputting a sound cable, or they can be incredibly complex cabinets with features ranging from numerous ports and internal baffles to acoustic insulation and composite materials used in their construction. The main point of housing loud speakers and PA speakers in cabinets is not simply to make them look neat and tidy, although that is one benefit. The cabinet actually provides a useful function in preventing competing sound waves from interacting with each other and distorting the end product. This is because the diaphragm that the speaker driver uses to create the sound we hear generates sound waves both at the front and the rear, and these will be out of sync with each other, thus creating a distortion if not dealt with adequately. Other side effects include echo and reverberation, as the sound waves would reach the audience at slightly different times as they travel on different paths through the loud speakers towards them. In addition to minimizing these unwanted side effects, loud speakerâ??s cabinets also help to manage the vibrations which are caused by the driver frame, as well as the buildup of heat that is associated with amplifiers, driver voice coils and other moving components in PA speakers.
