The Lubell 9484 is a proven in-wall Underwater Speaker system that is safe, durable, and powerful. In fact, the Lubell 9484 is the world's only piezoelectric underwater loudspeaker that operates under UL 30 volt class 2 legal limit and meets National Electric Code 680.27 and International Residential Code E4106.9.3 legal requirement for including an approved metal forming shell and captive metal grille. (PVC NICHE AND GRILLE MAY NOT BE USED FOR ANY UNDERWATER SPEAKER INSTALLATION UNDER ANY CONDITION PER NEC.) Although UL listing of the low-voltage Lubell LL916 underwater speaker is not required under National Electrical Code, the required commercial sound amplifiers (class 2 power supply) are UL listed, and have audio output circuitry determined by UL to be below the voltage limits for electric shock hazard as established by the 813 Standard.  Amplifiers are listed on this page and on dealer price lists.

Lubell Underwater Loudspeakers have become the most popular underwater speakers in the world since 1969.  Their superior patented design provides the highest documented efficiency, broadband response, and POWERFUL crystal clear sound from the lowest voltage. Because of the increased interest in water aerobics, lap swimming and synchronized swimming, built-in Lubell underwater speakers have become a standard feature in major college and luxury resort pools around the world. Swimming laps to the sound of underwater music or your favorite TV or talk-radio program is an enjoyable way to pass the time!

The 9484 is designed for installation at 6' (1.83m) optimum depth by licensed contractors during new concrete/gunite pool construction, and includes: A9000/2 Rough-in Kit (UL listed stainless steel niche with mating stainless steel grill), and the LL916ST-50 UW Speaker Kit (Lubell LL916 PVC transducer with 50' cable, 21007 speaker support, and AC205B 25V audio isolation transformer box). Amplifier NOT included.

For proper operation and to maintain 5 year warranty, 25 volts rms MUST NOT be exceeded to the supplied audio transformer box and underwater speaker -- regardless if using one speaker or eight speakers. We recommend and offer the following amps: InterM A-120 mixer-amplifier for 1-3 speakers; Peavey UMA1502 mixer-amplifier for 4 speakers; Peavey IPA300T power amp for 5-8 speakers. Each underwater speaker connects to output of individual AC205B transformer box, then inputs of multiple boxes connect in parallel to the 25V speaker line (supplied from UL listed GFCI protected amplifier only).

The 9484 must be installed as near to 6' (1.83m) depth as possible for proper low frequency response and coverage. Use two Lubell 9484 kits for pools up to 20' x 40'; Three for 25'/30' x 50/60' pools; Four for 25 yard lap or Olympic pools; Six for 82'/115' x 48'/64 pools; Three to eight units for personal Lap pools or 50 meter Olympic pools.
