UW30
UW30-100
Underwater
Loudspeaker
General Product Description
The UW30 represents a depar ture in the design of
underwater sound sources. Its unique design, U.S. Patent
#3,670,299, utilizes the case’s structural enclosure as the
sound transducer. This development makes possible a
speaker that has no metal parts exposed to the outside,
thus eliminating rust, corrosion or other causes of short-life
expectancy. The transducer principle and its strong
construction allow the UW30 to operate at much greater
depths than any prior type of underwater loudspeaker design.
The 12.7-ounce ceramic magnet and state-of-the-art
voice-coil construction ensure full-fidelity response with the
lowest possible distortion throughout its power range.
The UW30 is equipped with a waterproof, 3 conductor 15.24
m (50-ft.) cable. The UW30-100 features a 30.48 m (100 ft.)
cable.
The UW30 underwater loudspeaker is designed for
permanent installation and completely submerged operation.
All internal components are encapsulated with a “hot-melt”
(Polyamide Copolymer) process. The outer case is
constructed of high impact ABS (Acrylonitrile butadiene
styrene) plastic. Ideal for installation in both fresh and
saltwater pools, the UW30 can even be installed in ocean
environments without adverse effect. Problems such as
corrosion and electrolysis damage inherent in all or partial
metal underwater speakers are completely eliminated by the
plastic construction of the UW30.
A single model UW30 will deliver uniform sound throughout
moderate pools, up to 30 by 30 feet. For larger pools, up to
30 by 60 feet, two speakers should be used. If a high level of
turbulence is to be overcome, such as swimming and diving
instruction classes, several speakers should be used. The
noise level in the water will not only be more effectively
overcome, but it will also allow each speaker to be operated
at a lower power level thus avoiding excessive sound
intensities in the immediate vicinity of the speakers.
Underwater speakers are required equipment for many
activities in commercial and luxury resort pools. As specified
by the American Athletic Union, underwater speakers are
required for synchronized swimming events and instructions
in Olympic pools. They are used for water ballets and similar
water shows. When underwater speakers are installed in
resor t and private pools, the effect of music played
underwater is truly an enchanting experience.
