Overview:

The Active UCS1P is the ideal active subwoofer solution for use with any

combination of Unity™ loudspeaker full-range cabinets. The 1500-watt

integrated power amplifier takes full advantage of the cabinet's horn-loaded

design and single 15-inch long excursion driver to deliver enough bottom end

support for virtually any PA application.

The unmatched performance of the UCS1P is the direct result of outstanding

cabinet design combined with innovative integrated electronics designed to

maximize the UCS1P's output. The UCS1P can be connected to any line or

speaker level source via the XLR / TRS Combi-jack input. Built-in crossover

circuitry means the UCS1P can be added to any system without complicated

external crossovers being required. Multiple UCS1P's can be integrated into any

setup using the XLR or 1/4" TRS balanced thru put on each power module.

The UCS1P is made with a solid 15mm 11-ply birch plywood cabinet construction

and has a heavy gauge perforated metal grill to protect the components.

Integrated wheels and bar handles make moving and stacking the UCS1P as easy

as it can possibly be for a subwoofer in this class.

The UCS1P comes in a black carpet covering to mate with the U15, U215

and U15P.

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."
