Since 1969, Lubell Labs has been manufacturing the world's most popular and powerful underwater loudspeakers. With their heavy-duty construction and documented broadband performance recognized by the US Navy, Lubell underwater speakers have become the top choice for professional sound engineers globally. The Lubell LL916C was selected over international competitors for use at the Sydney 2000 and London 2012 Olympic Games, the Manchester 2002 Commonwealth Games, and the Aquarius Underwater Habitat in the Florida Keys.

LL916, LL916H, and LL916C Pistonic Piezoelectric Underwater Speakers

The portable Lubell Labs LL916 series underwater loudspeakers are efficient, full-range, pistonic piezoelectric acoustic transducers developed and manufactured by Lubell Labs in Columbus, Ohio, USA. As the inventor of the underwater speaker, Lubell Labs has created a unique design (Patent # 3391385) that offers the highest output levels and widest frequency response of any commercial underwater speaker on the market. This makes the product ideal for applications such as synchronized swimming, lap swimming, diver recall, and many others in pools, rivers, and oceans. In contrast to some competitors who compromise safety by running over a thousand volts through their underwater speaker cables, Lubell Labs adheres to safe engineering practices by operating at voltages of 20 volts or less for their underwater speaker cables.
