•  Never open the cabinet or remove the metal control

or damage to the unit.

We recommend that you place your woofer further 

•  Protect it from prolonged exposure to direct sunlight 

than two feet away from your TV, VCR, DVD player, 

and other direct sources of heat, such as heating

•  To prevent fire or shock, do not expose the unit to 
rain or moisture. If fluid or a foreign object should 
enter the unit, immediately turn off the power contact 
your Earthquake dealer.

•  Avoid excessive exposure to extreme cold or dust.

•  Do not place heavy objects on top of the unit.

•  Do not place the subwoofer with its control panel 
against the floor.

•  If you wish to place your woofer so the drivers face 
the floor and ceiling, thereby moving up and down, 
use at least 1-1 ½ inch high spikes or feet for support. 
They may be attached either with screws or self-stick 
backing . This arrangement will impart substantial 
house and floor shaking motion.

Heat Rise

•  Allow adequate ventilation around the metal control 
panel of the subwoofer. 

•  Do not let anything come into contact with the panel 
and keep at least two inches away from any walls.

The metal control plate serves as the amplifier heat 
sink and also as a conduit to remove internal heat to 
the outside and into the atmosphere. It can reach 
temperatures of 60° C, which will feel hot to the touch, 
using nerves of flesh and blood as temperature 
sensors. As uncomfortable as it may feel, 60 degrees 
C cannot burn you, and in fact is almost cool to 
copper, silicon, steel, and aluminum the material from 
which your woofer is constructed.

AC Power Considerations

Ensure that the unit is plugged into an outlet capable 
of supplying the correct voltage specified for your 
model.

Unplug your subwoofer's power cord from the 
electrical outlet if it will be left unused for a long period 
of time.
