SPL Requirements – How Loud?
The EVID C8.2 is a great speaker to employ when higher SPL are required. The fidelity
and bandwidth of the unit is substantial and is ideal for applications requiring high quality
foreground music reproduction. The C8.2 has substantial low frequency energy down
below 70Hz. This is more than sufficient for most applications.

Layout – How Many?
As we indicated earlier the number of speakers required to cover the job will vary
depending on three factors:
depending on three factors:
• Coverage angle specification of the speaker
• Ceiling height
• Degree of overlap desired
The chart below shows the effective coverage diameter of the EVID models assuming a
4-foot listening plane height. Using these figures you can lay out a coverage pattern for
the job after deciding the overlap criteria.

The “High Ceiling” Solution - A Replacement for the 920-8B
The EVID C8.2HC is the perfect replacement for the EV 920-8B in many installations.
The waveguide coupled controlled coverage acoustic design and the high power-handling
make the package ideal for Ballrooms, Gymnasiums, Smaller convention centers etc.
The chart below gives a summary of the critical specifications of the C8.2HC and the
920-8B. Note that while the 920-8B can deliver more absolute SPL, the tighter coverage
pattern of the C8.2HC provides more intelligibility at lower volumes so the net effect is a
more efficient system design.
