The EVID 4.2 and 8.2 – Full Range Models with Punch
The EVID C4.2 Perfect for conventional rooms. It has excellent bandwidth in an
esthetically very unobtrusive installation profile. It’s compact design fits in tight areas.
Fully rated for use in air handling spaces. It’s 4” woofer and waveguide coupled titanium
coated dome tweeter give smooth, wide frequency response. The enclosure is ported and
tuned to provide surprising bass response in such a compact package. Features an easy 3-
point mounting system for quick installations. Comes complete with mounting support
ring and tile rails. No additional accessories needed for most installations.
The C4.2 would be ideal for most office spaces along with smaller restaurants and retail
space where lower volume levels are used. It fits in close spaces and has a wide 130-
degree dispersion pattern for efficient coverage.
The EVID C8.2 is also unique in providing extremely high fidelity in a flush mount
ceiling speaker. The secret is the optimally tuned enclosure coupled to a large 8” coaxial
driver. The large enclosure ensures a full bottom end while the waveguide coupled
tweeter gives uniform coverage for the high frequencies.

The 10.1 - Finally a Compact True Ceiling Subwoofer
So often ceiling systems had to rely on expensive surface mount subwoofers or
inadequate ceiling/flush mount options. In designing the 10.1 we started with a mass
optimized 10” woofer and a dual ported and tuned enclosure. The internal damping
provides resonance free performance down to 45Hz.

The Basics
Selecting & Positioning Ceiling Loudspeakers
Several key criteria determine the type and quantity of ceiling speakers to employ in a
job.
job.
• Room size
• Coverage density desired
• Ceiling height
• Type of audio program material being played
There are specific EVID ceiling models for the job depending on the specifics of these
criteria.
In the traditional approach to overhead-distributed systems, loudspeakers are located in a
grid arrangement whose dimensions are dictated by the room height and the directivity of
the speaker elements. Two basic placement patterns prevail: square spacing, and
hexagonal (or crisscross) spacing.
In addition to the spacing pattern, the designer must choose between three density types,
designated respectively as edge-to-edge, minimum overlap and center-to-center. The
