What typical subwoofer/satellite system configurations are possible?
The EVID Series contains a variety of models, allowing great flexibility to configure a
system to fit the requirements of many different applications. Some typical examples are
illustrated at the end of this guide. It is important to remember that the C10.1 works very
well with all of the EVID surface mount models also.

How large an area can an EVID ceiling system cover?
A system consisting of one C10.1 subwoofer and six to eight C4.2 or eight C8.2 satellites
can cover up to a 4000 square foot room with balanced, even coverage. The estimate of
4000 square feet is a typical coverage area. You can scale the coverage up or down to
adjust for applications with different SPL requirements and different size rooms.

What are some techniques to properly balance the levels between the
subwoofer and satellites?
subwoofer and satellites?
The required sensitivity balance between the subwoofer and satellites varies by the
musical requirements of the application. A sports bar or health club for example might
require much more bass content than does a low level background music system.
Sensitivity of the satellite section varies depending on the particular satellite model
chosen, the number of speakers employed and the wiring configuration. Higher satellite
sensitivities result in less relative subwoofer level.
It’s generally best to position the subwoofer after the rest of the system is installed,
changing its location to achieve the optimum bass level. The acoustic volume level of the
subwoofer can be raised or lowered by moving its position within the room. Beginning at
a corner junction in the room you can enhance bass output by moving the subwoofer
closer to the ceiling or floor; you can reduce apparent bass output by moving it out onto
the center of a wall. You can decrease bass output further by suspending it in the middle
of the room.

EVID ceiling speakers incorporate high performance transformers that are very stable at
all frequencies in their range and exhibit very little low-frequency saturation. The
matching transformers in all the EVID units are designed to provide full rated output
