Up for sale is the Coliseum version of the famous U15 speaker. Engineered for the serious pro audio user, the CU15 is among the most advanced, most versatile and most efficient high-powered portable P.A. boxes available on the market today. The CU15 is a radical loudspeaker cabinet design utilizing the patented Unity™ Summation Aperture Horn Technology invented by loudspeaker designer Tom Danley. The CU15 provides remarkably even high/mid frequency distribution from its 60º x 60º horn assembly. The combination of that conical, constant directivity horn, a 15-inch Neodymium-magnet woofer and our unending attention to details, right down to the ideal trapezoidal cabinet design, has yielded an extremely versatile speaker. The CU15’s Unity™ horn combines a single 1-inch-throat (1.75 diaphragm) compression driver with three 5-inch ceramic magnet midrange drivers firing through time-aligned slots in the horn-wall. This seamlessly blends the mid and high frequencies while providing exceptional power capacity and clarity from 300Hz to 20kHz. An advanced, high-efficiency, 800-Watt fifteen inch woofer with an ultra lightweight Neodymium magnet provides clean, powerful lows to complete the package.
