Underwater/Submersible Speakers
The MM2 series, along with the UW30, represents a departure from conventional designs of underwater sound sources.
The MM2 series has become the standard for paging and notification in adverse environmental conditions. It is commonly used in military and civilian applications and is uniquely suited to marine environments because it is totally waterproof and submersible yet delivers clean, intelligible audio.
For commercial and residential pools, the UW30's unique, patented design uses its structural enclosure as the sound transducer. Underwater speakers are required equipment for many activities in commercial, luxury resort pools, synchronized swimming events, Olympic pools, water ballets, and water shows. The UW30 delivers high-fidelity sound with low distortion, and the effect of underwater music is truly enchanting.
Underwater/Submersible Speakers
The MM2 is a 25-watt, submergence-proof design (U.S. Navy specification), with a serrated mounting bracket that allows for a 90 degree swivel. The MM2 is ideal for use near water or spray. The gray MM2 features an 82 degree x 82 degree dispersion pattern and 16-ohm impedance. Each unit is fully protected against damage from high humidity, salt water and other environmental conditions.
The MM2F is a 25-watt, submergence-proof, paging projector (U.S. Navy specification) designed for flush-mounting in a bulkhead or wall. The MM2F is ideal for use near water or spray. The gray MM2F features an 82 degree x 82 degree dispersion pattern and 16-ohm impedance. Each unit is fully protected against damage from high humidity, salt water and other environmental conditions.
The University Sound series MM2TC is a conservatively rated, 25-watt, submergence-proof speaker designed for wall, ceiling, or bulkhead mounting. The driver employs a diaphragm with a phenolic, impregnated linen-base and two-inch voice coil with W-shaped, Alnico V magnet structure. Provisions are made in the housing for installation of a 30-watt matching transformer. The voice-coil and diaphragm assembly is protected by a special anit-fungicide treatment, and is easily accessible for cleaning by removal of the die-cast reflector on the front of the speaker. The MM2TC is self-draining and designed to withstand fungus, dust, salt spray, live steam, and gases. It is built to penetrate high noise levels in boiler rooms, mines, and railroads.
The UW30 underwater speaker is equipped with a waterproof, three-conductor, 50-foot cable. It features eight-ohm impedance, and is available in pool blue. Underwater speakers are required by the American Athletic Union for synchronized swimming events and instructions in Olympic pools. They are also ideal for water ballets or similar water shows and resort or private pools.
Built for installation in both fresh and salt water pools, the UW30 can even be safely installed in ocean environments. The speaker is designed for permanent installation and completely submerged operation. Problems such as corrosion and electrolysis damage are completely eliminated by plastic construction. The 12.7-ounce ceramic magnet and state-of-the-art voice-coil construction ensure high-fidelity response with low distortion throughout the power range. One speaker is recommended for pools up to 30 feet x 30 feet, or two speakers for pools up to 30 feet x 60 feet.
