Underwater Speakers

Underwater Speakers

The speaker guts SL600UC contains a 20-watt loud
speaker of 8 ohms, to be installed under water in our standard niche (pu9). The main working part is completely encased in rubber, which eliminates corrosion and electrolysis
damage.
Because water is denser than air, sound travels well but
does require a little more power to move the water. Care
must be taken not to overpower the unit as damage may
occur.
As most amplifier systems require two speakers for stereo
reproduction, two speakers must be connected to prevent
amplifier damage.
Each underwater speaker must be isolated from the amplifier unit by means of the isolation transformer (SL600TC).
Each speaker unit comes with a length of waterproof double
insulated cable embedded into the rubber housing, this can
be extended if required. A pools side junction deck box
(PU10N) is recommended for ease of future access.
The Speakers should be installed to a depth of at least 1
metre, to avoid sound disruption by surface currents. Two
loudspeakers will be sufficient for a quiet swimming pool of
20 meters x 10 meters.
These Speakers are not designed for out of water use, if
used out of water over heating may occur.
Excessive bass frequencies will damage this unit therefore
do not apply bass boost also over-driving these speakers
will void any warranty.
Please ensure these speakers are connected to the correct
power source – LOW IMPEDANCE AMPLIFIER ONLY via
the isolation transformer.
DO NOT CONNECT TO MAINS POWER.
