The DX1577 is a bi-amplified, 3-way coaxial loudspeaker that provides the output and pattern control of two 15 inch transducers in an enclosure size that would typically house a conventional 2-way system. Its coaxial transducer and 75° x 75° horn provides effective coverage in situations where traditional 45° and 60° vertical patterns are too narrow. The enclosure’s 40° trapezoidal shape may be mounted close to walls or in tight-packed horizontal arrays; alternatively the enclosure may be rotated for mounting close to ceilings or in tight-packed vertical arrays.
