Unity™ Series
U15 Speaker - 800w 15 / 3x5 inch / 1 inch

Engineered for the serious pro audio user, the U15
is among the most advanced, most versatile and most efficient high-powered portable P.A. box available in 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.

Unity™ Series Overview

 The Unity™ Series of loudspeakers 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 Unity™ Series pushes the limits of modern state-of-the-art sound reinforcement technology, which features a radical new loudspeaker horn design, arguably the first major evolution in horn technology in the last 60 years. Ultra clear reproduction through the high-mid band with extremely linear frequency response has been achieved using the patented* Unity™ horn technology, licensed from Sound Physics Labs Inc. Unity™ horn technology combines a single 1" throat with a 1.75” diaphragm high frequency compression driver alongside three 5” ceramic magnet midrange drivers on a single, highly efficient conical horn. This combines high and mid frequency energy in a single 60º x 60º conical horn that produces frequencies from 300Hz to 20kHz. Patent holder Tom Danley explains it this way. "With a conical horn, one sees that at the compression driver exit, the expansion rate is very rapid at high frequency cutoff, and since the expansion rate acts as a high pass filter, the low frequency energy does not couple to the mouth. Move a few inches toward the mouth and one finds the expansion rate is much slower and suitable for low midrange, if only that was where the driver was. All one has to do is obtain a mid driver, suitable for efficient horn loading in that frequency band and find the point in the flare where the expansion rate is suitable for that frequency range and couple the sound in at that point. Because the compression driver and each mid driver are less than 1/4 wavelength apart, their output combines fully and coherently, something which cannot happen if the driver were further than about 1/3 wavelength apart."

*U.S. Patent # 6,411,718 B1

So what exactly does all this mean?

What it means is that all four drivers mounted in a Unity™ horn measure and act like a single point source. The sound produced from the combined 4 drivers act like a single driver. Additional DSP (Digital Signal Processing) is not required to time align the Mid and High frequencies together like in many other conventional systems. This is especially important as it minimizes, if not eliminates, the major phasing and lobing problems typically associated with your standard multiple horn 3-way box. By mechanically time
