The LA18 is a 2-way high performance linear array loudspeaker system employing 1x 8” LF and a 1.4” exit HF connected to an acoustic boundary element optimized waveguide. The precise 90 X 10 (h x v) constant directivity horn delivers accurate, consistent coverage area when deployed for mains PA applications. The LA18 horn feautures the proprietary RMS-Acoustics confocal elliptic waveguides, made with cutting edge additive manufacturing technology. The LA18 enclosure is constructed from birch hardwood plywood, features integrated side handles, an impact and UV resistant polyurethane paint finish, and high resolution integrated interconnect rigging. The front of the loudspeaker cabinet is protected by a hexagonal punched and laser cut steel grill, backed with an acoustically transparent foam.
