EAW KF850 Series
The KF850z has been the touring system standard for well over 15 years. Legendary KF850 Virtual Array performance has been enhanced with a neodymium Orbital Magnet Array HF driver, offering increased surface area for better cooling and reliability. An upgraded HF horn extends response and fidelity while minimizing distortion. The MF subsystem is based on EAW's Radial Phase Plug design used in other premium KF Series models such as the KF750.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 exsiting 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
