Engineered for the serious pro audio user, the U15 is among the most advanced, most 
versatile and most efficient high-powered compact PA cabinet available in the market today.
The unparalleled clarity and precision of the patented Unity™ Summation Aperture conical horn
when combined with the single 15-inch woofer deliver extreme intelligibility and performance
unmatched by any competitive loudspeaker in this class.
The compact footprint and relative light weight of the U15 easily makes it a first choice for
front-of-house applications, drum monitor, side fill, front and down fill or virtually any situation
where a professional quality sound reinforcement system is required.
The sonic clarity and smooth frequency response also makes the U15 a great PA cabinet for high
volume recorded music playback applications. 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 extremely high sound pressure 
levels from its high-efficiency 1000-watt (Program), 4 ohm format.
The U15 can be easily driven as a bi-amplified loudspeaker by way of a switch on the rear jack
plate, and used with any Unity or 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 cabinet’s trapezoidal shape was designed with multi-box, tight pack arraying in mind. 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.
The Unity U15 is made with solid 15mm 11-ply birch plywood 
cabinet construction and has heavy gauge perforated metal grille
to protect the components. Integrated bar handles and stand-
mount adaptor makes it an ideal cabinet for highly mobile front-of
house applications where quick and easy set-up and tear down is
required. Integrated flypoints allow Unity U15 to be flown in any
array or installation quickly and safely. The U15 is available in two
cabinet finishes including a rugged black Ozite carpet covering,
ideal for mobile PA and rental houses (U15), or in a black painted
finish (U15B) more suited to installation or touring systems.
