Legacy Series - CU15

1000w 15 / 3x5-inch / 1-inch

Engineered for the serious pro audio user, the CU15 is among the most advanced, most versatile and efficient high-powered compact PA enclosures available on the market today. The unparalleled clarity and precision of the patented Unity™ Summation Aperture conical horn, when combined with a high-performance 15-inch Neodymium woofer, delivers amazing intelligibility and performance unmatched by any competitive loudspeaker in this class.

The compact footprint and relative light weight of the CU15 easily make it a first choice for front-of-house applications also as a drum monitor, side fill, front fill and down fill, or virtually any situation where concert-quality sound reinforcement is required. In addition, sonic clarity and smooth frequency response also make the CU15 a great choice for recorded music playback applications. Even with the most demanding recorded programs, the CU15 has the high fidelity to put it on par with some of the best studio reference monitors. But unlike traditional reference monitors, the CU15 is capable of producing extremely high sound pressure levels from its high-efficiency 1000-Watt, 4 ohm format, all with sparkling clarity.

The cabinet's trapezoidal shape was designed with multi-box, tight-packed arraying in mind. As well, due to the nature of the conical horn, the polar pattern remains quite constant on all axis, making it ideal for use upright or on its' side, with no need to rotate the horn.

To further facilitate installation of the CU15 in virtually any application, we also offer the FH1W flying hardware which can be used to fly cabinets in clusters of two or three box arrays.

The Unity CU15 enclosure is entirely constructed of solid 15mm 11-ply birch finished in durable white paint, designed to be painted over as you desire. It also features a heavy-gauge perforated metal grille to protect the components. Multiple reinforced flypoints make it extremely easy to install on any angle, hung as a single cabinet or in an array.
