UW30
Underwater
Loudspeaker
General Product Description
The UW30 represents a departure 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‑delity 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 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 specied
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 resort and private pools, the effect of music played
underwater is truly an enchanting experience.
