U15

2 models to choose from:

Limited stock available in select stores only

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 60 x 60 horn assembly. The combination of that conical, constant directivity horn, a 15-inch high power 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.

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 specifically 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 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 1000 watts at 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.

There's not a lot of passive, three-way, 15" speaker enclosures on the market. I bought a pair of these initially, a month ago without the optional processor that's designed to go with it. I didn't want yet another piece of equipment to have to plug in and carry, when gigging, if I didn't absolutely need it. I lug enough stuff as it is. At first, I liked them. They sounded good, nice mids/highs. Not harsh. But as the honeymoon wore off, I personally found that the bottom end was honky. Not particularly "warm". The kick drum for instance had too much "plunk" and not enough "UMPH". Loud as hell, though. E.q.ing didn't really solve the issue. The warmth just wasn't there. I did a couple of gigs with them and honestly wasn't really that impressed with the overall sound. So, I bought the UP15 that goes with it, in hopes that it would solve the problem. Plugged it in and "BOOM"!! It was a different speaker. There was that really nice, round bottom that I'd been looking for. They sound great. They're heavy pigs and a drag to carry alone, especially if there's stairs to contend with. A cart or casters are in order. But they're solid, like all Yorkville stuff and now I can use with them with confidence that I'm sounding the way I want to sound. I did my first gig last night with the processor hooked up and it was a different ballgame. I'd like to try them now, with a sub and utilize this system to it's fullest potential. Not keen on lugging a sub (or two) around though.
