Passive Series

Overview

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.

U15

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
