UW30 represents a departure from conventional underwater sound source design. Utilizing the the water proof barrier as the sound source radiator provides more full range sound in one of the toughest acoustic environments.

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‐fidelity response with the lowest possible distortion throughout its power range.
