This Frequency Plot is for a 1 Volt (rms) drive, with 20Vrms add ~26dB to obtain SPL




Recommended Installation Depth: 1.8 meter, can be used at shallower depth

Compatible with Salt water, Chlorination Systems and Heated Pools

We recommend 1 underwater speaker for every 6m of length of the pool.

The amplifier has the possibility to connect up-to 3 underwater speakers.


Stereo sound is not an issue underwater due to the fact that we cannot distinguish the direction of the sound we hear. However the amplifier included mixes available channels accordingly and these sounds are placed into the water.
