EAW KF850T Horn Loaded Sound Reinforcement Virtual Array® System (c1988)
The KF850 has been developed as the result of Kenton Forsythe’s 15 year effort to improve the sonic performance and physical packaging of concert sound loudspeaker systems. During this time the concepts behind the KF850 evolved from a unique integration of acoustical, electronic and mechanical engineering science and technologies. Every step of the way EAW has employed intensive laboratory testing and real world concert testing to refine the design principles, including the Virtual Array TM design, cone driven mid bass, flying hardware, and polyurethane reinforced wood construction techniques.
