The sonic clarity and smooth frequency response also makes the CU15 a great PA cabinet for
high volume recorded music playback applications. With pre-recorded music the CU15 has the
hi-fidelity to put it on par with some of the best studio reference monitors. But unlike traditional
studio reference monitors, the CU15 is capable if putting out extremely high sound pressure
levels from its high-efficiency 800-watt, 4 ohm format.

The CU15 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 CU15 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 CU15 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
standmount adaptor makes it an ideal cabinet for highly mobile front-of house applications
where quick and easy set-up and tear down is required. The Coliseum CU15 enclosure has
been redesigned specifically for the installation market. Unlike the Unity™ U15, the touring
version of this cabinet, the CU15 enclosure is covered in an unobtrusive white paintable
finish, and it has been stripped of extraneous touring hardware not required on an
installation loudspeaker box.
