» General Description
UW30 represents a departure from conventional underwater sound source design.
Built for installation in both fresh and salt water pools, the UW30 can even be safely installed in ocean environments. Designed for permanent installation and completely submerged operation. Problems such as corrosion and electrolysis damage are completely eliminated due to the plastic construction. The ceramic magnet and state of the art voice coil construction assure full-fidelity response with the lowest possible distortion throughout its power range.
One speaker is recommended for pools up to 9 x 9 metre, or two speakers for pools up to 9 x 18 metre.
Flush Mounting For new pool construction and modification of older pools, installing the UW30 flush 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 flush 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.
For maximum protection against speaker overload, fusing the line from the amplifier 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.
