Yorkville U15B Unity Series Full Range Loudspeaker (Ultrathane Black)

Yorkville U15B Unity Series Full Range Loudspeaker (Ultrathane Black)

Yorkville U15B Unity Series Full Range Loudspeaker (Ultrathane Black)

The Yorkville U15, engineered for the serious pro audio user, 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, which was invented by loudspeaker designer Tom Danley and licensed from Sound Physics Labs Inc. The U15 provides remarkably even high / mid frequency distribution from the 60º x 60º horn assembly.

The combination of the conical, constant directivity horn, 15" new technology Neodymium woofer and our unending attention to details, right down to the ideal trapezoidal shaped cabinet has yielded an extremely versatile product. The U15 Unity horn combines a single 1 inch throat (1.75" diaphragm) compression driver with three 5-inch ceramic magnet midrange drivers on a single highly efficient conical horn. This combines high and mid frequencies driver components in a single 60º x 60º conical horn that produces frequencies from 300Hz to 20kHz. Added to all this is the new technology, ultra lightweight Neodymium 15? woofer to complete the package.

The U15 can be easily bi-amplified by way of a switch on the rear jackplate, or used with any élite series subwoofer for extended low frequency support. The UP15 Unity processor, designed specifically to optimize the sonic characteristics of the U15 has also been developed to ensure trouble free, ??plug-and-play? full range or Bi-amp operation with or without a subwoofer.

The compact and ultra efficient U15 is a trapezoidal shaped, 800 watt cabinet with a carefully chosen 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 professional quality sound reinforcement system is required. The unparalleled sonic clarity and smooth frequency response also makes it great for music playback. With pre-recorded music the U15 has the hi-fidelity to put it on par with some of the best studio reference monitors. But unlike traditional studio reference monitors, the U15 is capable if putting out a very high-efficiency 800 watts into 4ohms. The trapezoidal shape was designed with multi-box, tight pack arraying in mind.

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 ever rotate the horn.

Warranty Information

In Canada and the United States Yorkville offers an "EVEN IF YOU BREAK IT" two year unlimited warranty on most of it's products. This warranty has made Yorkville famous. Not only because of the fact that it is one of the few real warranties that protects the customer rather than the company, but also because it wouldn't be possible for Yorkville to offer this warranty if their products broke down!! Rock solid design and construction will guarantee that your unit works when you need it to, but just in case...


Coverage by the Yorkville two & ten year unlimited warranty is transferable and it is not necessary to register your name. If, for any reason, any product manufactured by Yorkville Sound should fail within two years (ten years on all wooden enclosure elements) of the original purchase date, Yorkville will repair it free of charge. This includes speaker products. Simply contact Front End Audio with original proof of purchase and it will be repaired free of charge. Please keep in mind that freight charges and damages caused as a result of major accidents or natural disasters (such as fire, automobile wrecks, tornadoes, etc.) are excluded from Yorkville's warranty.

What We Think - Yorkville U15B Review

"The Unity Series loudspeakers by Yorkville are, without a doubt, some of the most impressive speaker systems I??ve ever worked with. Unity Series speakers definitely perform their best in mid to large-size venues and in outdoor settings where consistent coverage over long distance and a wide area is required, but will fill smaller halls easily without being overly loud.

"Unity speakers are a unique design with the U15 and U215 full-range cabinets incorporating a Tom Danley designed midrange horn with a 4-driver configuration to provide extremely smooth and even coverage. When matched with the proper power amps, which Yorkville offers, and Unity Series speaker processors to optimize their performance, Yorkville Unity Series speakers are perfect for handling pretty much any job where exceptional quality sound is a must."
