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 specied

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.

Installation

Flush Mounting

For new pool construction and modication of older pools, installing

the UW30 ush with the sides of the pool makes a very neat and

unobtrusive installation. The speaker is mounted in a wet‑niche

(Paragon Part #68102 or equivalent) in the same manner as an

underwater light. Figure 1 shows a typical installation. The speaker

is mounted up to 1.2 m (4 ft.) below the surface of the water and

ush with the side of the pool. (For installation in water depths lower

than recommended, please contact factory.) A marine plywood

or stainless steel mounting ring or face plate is recommended.

(Paragon Part # 68103SS stainless steel or #68103 bronze polished

chrome or equivalent). Several pool equipment manufacturers have

wet‑niches available into which the UW30 may be installed. See your

local pool supplier for further information. You may contact Paragon

at: KDI Paragon, Inc., 341 Route 55 Westwing, LaGrangeville, NY

12540, Phone: (845) 452‑5500

Fusing

For maximum protection against speaker overload, fusing the

line from the amplier is recommended. In the event of accidental

overload, it is much easier to replace a fuse (which is above the

water) than to replace or have the speaker repaired. Installing a 25

ohm, 20 watt resistor in parallel with a 1.5 ampere, fastblowing fuse

in series with the speaker is recommended. See Figure 2.

Layout of Speaker in Pool

When underwater speakers are installed, particularly in smaller

pools where only one or two speakers are needed, they should be

located in the deep end of the pool. The above recommendation

will effectively equalize the intensity of sound throughout the pool.

For installations in large pools, such as at country clubs, municipal

facilities, etc., the speakers should be located around the periphery

of the pool. A good rule to follow for large pools is one speaker for

every 900 square feet (83.61 square meters) of pool surface at

the deep end and one speaker for every 1,200 square feet (111.48

square meters) of pool surface for the shallow end. Of course, for

high‑noise conditions in the pool, the number of speakers should

be doubled for best results.
