The LA212x is a 3-way fully horn loaded, axially symmetric, line array element, capable of producing crystal clear, detailed and extremely powerful audio performance over distance, with an exceptional 90° horizontal constant dispersion control. Being completely symmetric this line array is capable of generating virtually identical acoustic sound patterns on the right and left which allows for an easy, accurate and symmetric alignment. It incorporates a number of technologies to produce a coherent vertical wave front, extreme sound pressure levels with exceptional accuracy and specially consistent horizontal coverage over a wide frequency range, kept down to 250 Hz. Maintaining directivity control over this wide bandwidth raises the ratio of direct-to-reflected energy, thereby increasing system intelligibility. The LA212x was carefully designed to precisely match all the path lenghts from the throat to the mouth of the device. The generated sound wave has a flat and isophasic wavefront that meets a diffraction slot which mantains a constant horizontal directivity. By vertically limiting and spreading on the horizontal plane, this line array, creates a cylindrical wave with minimal lobing when coupling with other units.
