Since its introduction in late 2003, the Unity Series has well established itself as one of the most advanced, most versatile and most efficient high-powered portable PA cabinet designs currently available. The radical Unity Summation Aperture Horn Technology provides remarkably even high / mid frequency distribution from the 60 x 60 horn assembly, delivering unmatched clarity and definition from a loudspeaker box.

Building on the popularity of the single 15-inch and horn Unity U15, the logical step was to offer that highly successful passive cabinet in a radically redesigned active version. The result is the 900-watt three-way 15-inch and horn U15P.

The radical nature of the Unity horn required a radical power amp solution to ensure optimum performance from the system. An integrated DSP provides three-way internal crossover, time alignment, component protection, limiting and an extremely accurate overall cabinet EQ. Time delayed output for accurate subwoofer alignment ensures the Unity U15P delivers maximum impact in systems where complex external processing isnt the preferred set-up solution.

The U15P uses a combination of amplifier topographies to ensure reliability and superior loudspeaker performance. Two Class A/B amplifier modules deliver 150-watts each to the 1.75-inch horn driver, and to the three 5-inch ceramic drivers that make up the Unity horn assembly. An additional three-tier designed amplifier module delivers 600-watts to the 15-inch neodymium woofer.

The U15P is built using 5/8-inch birch plywood cabinet construction. Integrated bar handles and standmount adaptor allows the U15P to be quickly and easily integrated into any mobile live PA system. The cabinets unmatched clarity and performance make an ideal choice as a repeater cabinet in large rooms and concert halls. Integrated flypoints allow the U15P to be flown in multi-cabinet arrays or installations without modification to the box. The cabinets trapezoidal shape was designed with tight-pack box arrays in mind.
