The JBL VRX-928LA 2-Way Line Array Loudspeaker System is a lightweight, compact, two-way line array speaker system designed for use in arrays of up to six units. The VRX-928LA is equipped with JBL's exclusive neodymium magnet Differential Driver woofer for high power. There are also two patent-pending, high-frequency neodymium compression drivers. The Constant Curvature waveguide mounts two compression speakers on a continuous arc. Adding additional speakers does not alter the arc, so all drivers work together as though they would be one single driver on a long waveguide. With amplitude shading you get the perfect shape to your array. The VRX-928LA can be mounted on a tripod, over the VRX915S, or use the integral rigging system. In fact, up to six VRX-928LA speakers can be mounted together in the same array for a nominal vertical coverage of up to 90°. Constant Curvature Array - The waveguide mounts two compression drivers on a continuous arc enabling them to work together acoustically as if they were a single driver Amplitude Shading - Convenient series of switches on each enclosures that controls the output of each high frequency section in the array Suspension and Rigging Dual Angle Pole Socket - JBL's dual angle pole sockets allow great flexibility in aiming the enclosure (not on - WH version) Differential Drive® Woofe
