Engineered for the serious pro audio user, the U15 is among the most advanced, most versatile and most efficient high-powered portable P.A. boxes available on the market today. The U15 is a radical loudspeaker cabinet design utilizing the patented Unity™ Summation Aperture Horn Technology invented by loudspeaker designer Tom Danley.
The U15 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 U15’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.SPECIFICATIONS
