Lubell Labs 9484 Underwater Speaker Kit

Lubell 9484

The Lubell Labs underwater speaker has become the most popular underwater loudspeaker in the world since 1968, as it is louder and clearer than any other competing product! Its unique design (U.S. Patent #3,391,385) utilizes its dual-piston PVC overmolded aluminum enclosure as the sound transducer, offering true pistonic operation with no exposed metal parts. Coupled with a powerful 8-cylinder piezoelectric engine (with efficiencies approaching 60% in a corrosion-free design), no other brand compares!

Because of the increased interest in water aerobics, lap swimming, and synchronized swimming, built-in Lubell 9484 underwater speakers have become a standard feature in Collegiate pools around the world. Coaches appreciate the ability to clearly and effectively communicate instructions to their swimmers via wireless microphones from the deck. When not coaching, upbeat music with select tempos (or metronome beats) can be played for swimmers to keep pace in an enjoyable fashion.

Lubell 9484 underwater loudspeakers have also become a standard feature in luxury hotel and resort pools worldwide. Swimming laps to the sound of underwater music, books on tape, or favorite TV shows is an enjoyable way to exercise! And in the event of an emergency or inclement weather, swimmers never miss the announcement to vacate the facility.

The included SP0604C4 Hayward stainless steel wet-niche (Lubell SKU A9000) should be installed at 6 foot (1.83 m) depth below the water line by licensed pool contractor / electrician during new concrete/gunite pool construction. (Underwater speakers are not offered for vinyl and stainless steel pools due to poor sound quality.) Niche must be bonded to Equipotential Bonding Grid per NEC 680.26 (B) and (C) (see drawing & article) along with all metal parts of pool structure. For home pools, one unit is recommended for installation in each 20 foot x 20 foot (6.1 m x 6.1 m) section of the pool. For deep Collegiate pools, one unit is recommended for each 37.5 foot x 37.5 foot (11.43 m x 11.43 m) section of the pool. Following are some suggested installation locations: 60' home pool, 75' & 90' lap pools, 50 meter Olympic pool.
