System Installation Considerations

There are several factors to consider before installing Earthquake Sound’s 

 

Edgeless RCS In-Ceiling Speakers

.

• What are the intended listening zones?

•  What system options and accessories might be required for features such 

as local sources, etc.?

•  From where in each zone will the listener prefer to control the system? Where 

will the remote gains be located? Where will the speakers be located?

• Where will the source equipment be located?

Connection Tips

•  Keep all power cords away from all signal cables to prevent humming from 

induced noise.

•  Choose reliable signal cable cords (Earthquake Sound also specializes in 

high-performance RCA cables and patches).

•  All speaker wires that are ran through the walls should be twisted to reduce 

potential hum noise pick up.

• Label both ends of all wires with the corresponding room location.

•  It is best to use a grounded electrical outlet to power the amplifier. Lack of 

input ground reference could be unsafe. Consult your electrical contractor 

about proper grounding.

  

The RCS In-Ceiling Speaker grilles are paintable and can accept virtually any 

type of paint. We strongly recommend the following:

1.  Remove the grilles from the speakers prior to painting them.

2.  Thin the paint prior to application, if needed. Spray and roller paint 

applications typically provide the best results. Note that you may need 

to apply multiple thin layers of paint to achieve the desired shade without 

losing sound quality due to clogging of the grilles.

3.  Let  the  painted  grilles  fully  dry  before  mounting  them  back  on  the 

speakers.
