OUR PART # U15
Yorkville's U15 is among the most advanced, versatile and efficient high-powered portable P.A. boxes available on the market. The U15 is a radical loudspeaker cabinet design utilizing loudspeaker designer Tom Danley's Unity™ Summation Aperture Horn Technology.
The U15 provides remarkably even high/mid frequency distribution from its 60° x 60° horn assembly. The combination of that conical, constant directivity horn, a 15-inch high power woofer and 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.
The U15 comes with a high-definition 3-way passive crossover featuring our exclusive PTC™ non-interruptive horn protection. However it can be easily bi-amplified by way of a switch on the rear jackplate, and using the optional UP15 Unity™ processor - designed to optimize the sonic characteristics of the U15. The UP15 has been developed to ensure trouble free, "plug-and-play" operation and further offers a subwoofer output.
The compact and efficient U15 is a trapezoidal-shaped, 800-watt cabinet with a crossover point to seamlessly match the directivity characteristics of the conical horn to the neodymium woofer. With such a compact footprint and weight, the U15 easily finds its home as a FOH speaker, drum monitor, side fill, front or down fill or virtually any situation where a quality sound reinforcement system is required. The sonic clarity and smooth frequency response also makes it great for music playback. With pre-recorded music the U15 has the fidelity to put it on par with some of the best studio reference monitors. But unlike traditional studio reference monitors, the U15 is capable of putting out a very high-efficiency 1000 watts at 4ohms.
Looking at a polar plot for a 3 box, tight-pack array one would notice how extremely well behaved it is. Furthermore, due to the nature of the conical horn, the polar pattern remains quite constant regardless of any vertical, or off-axis rotation put upon it. It acts the same on all vertical axis, making it ideal for use upright or on its' side, without the need to rotate the horn.
