The Diluvio™ Underwater Loudspeaker is the world’s only full-frequency, full-fidelity underwater loudspeaker. Backyard pool enthusiasts, lap swimmers and competitive swimmers agree the Diluvio™ turns any pool experience into something truly spectacular. The Diluvio™ brings water to life, allowing music and sound to be heard through the body below the water’s surface. The Diluvio™ can be used in two different ways. For a permanent installation, the Diluvio™ can be mounted inside a large light niche with a face ring kit (sold separately). For users who require underwater sound in multiple locations, such as synchronized swim teams, a tether can be attached to the Diluvio™ so it can be used as a drop-in speaker. The Diluvio™ Underwater Loudspeaker requires an amplifier for operation. Clark Synthesis recommends an amplifier stable at 4 ohms that can deliver 125-150 watts @ 4 ohms (per speaker).
