SAFETY WARNINGS AND GUIDELINES

 Turn off and unplug all equipment prior to making electrical connections, including

speaker wire connections.

 Reduce the volume level prior to making any change to the audio input source, e.g.,

changing radio stations or changing CDs.

 Ensure that the speaker terminal cover is properly secured to maintain the IPX6

waterproof rating.

 When using this speaker as part of a constant voltage speaker system, ensure that

the amplifier power is at least 20% higher than the total power settings of the

connected speakers.

 Most speaker damage is caused by clipping, which is heard as distortion. If you hear

distortion, reduce the volume level until the audio is no longer distorted.

 Take care to ensure that the speaker wire connections are properly polarized.

Inverted polarization can result in unnatural or attenuated sound, especially in the

bass frequencies.

 Do not use chemical cleaners or solvents to clean this speaker. Use only a soft, dry

cloth. Moisten the cloth with warm water for particularly stubborn deposits.

CONSTANT VOLTAGE VS 8-OHM SPEAKER SYSTEMS

A constant voltage speaker system differs from a traditional 8-ohm speaker system in that

it uses a step-up transformer at the audio source to raise the voltage and lower the current

on the transmission line. At the speaker end, a step-down transformer converts the signal

back to a normal speaker level voltage. This reduces power loss during transmission, which

allows for the use of longer speaker wire runs using smaller gauge wire.

Additionally, a constant voltage speaker system allows for the use of multiple speakers on

each channel, without the need for complicated impedance calculations and

configurations. In a constant voltage system, all speakers on a given channel are connected

in parallel and the complicated impedance calculations are replaced by simple wattage

calculations.
