UCS1
15-inch Compact Subwoofer
The UCS1 is the ideal passive subwoofer to use with the Unity™ U15 or U215
loudspeaker systems. This 1200-watt 8-ohm cabinet takes full advantage of its
horn-loaded design to deliver fierce bottom end from a surprisingly compact,
single 15-inch loaded passive subwoofer.
The performance UCS1 delivers from a box this manageable in size is the direct
result of outstanding loudspeaker cabinet design. Optimized horn flare geometry
careful attention to the front and rear internal chamber dimensions, as well as
the use of a high performance long excursion 15-inch driver gives the UCS1
surprising high output volume and extended bass response for a subwoofer
cabinet occupying only a total volume of just over 11 cubic feet.
The UCS1 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 UCS1 as easy
as it can possibly be for a subwoofer in this class.
The UCS1 comes in a black carpet covering to mate with the U15 and U215, or
is available in a black painted Ultrathane finish (UCS1B) for use with the
Ultrathane painted versions of the Unity™ loudspeakers. (U15B and U215B).
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
The Unity™ Series pushes the limits of modern sta
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.
where the driver was.
where the expansion ra
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."
