Welcome/Important Features
EVID™ C4.2
Perfect for conventional rooms. It has excellent bandwidth in an esthetically very unobtrusive installation profile. Its compact
design fits in tight areas. Its 4-inch 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.
EVID C8.2
The C8.2 has a specially tuned enclosure and 8inch woofer to provide amazing bass response.
The 1-inch waveguide-coupled tweeter give
smooth controlled coverage out to 20 kHz.
Perfect for installations where a f lush-mount
design is desired but demand for high-quality
audio exists. Features a 4-point mounting system to make installations fast and easy.
EVID™ C8.2LP
The C8.2LP is the same as the C8.2 but in a
low-profile installation package. Ideal for
tight ceiling spaces.
EVID™ C8.2HC
The EVID C8.2HC is ideal for high ceilings and
reverberant “problem” rooms. Its exclusive
ported, waveguide-coupled, 8-inch driver provides excellent intelligibility and definition.
The 8.2HC’s patent-pending design provides
great coverage control throughout the voice
range and above. No other ceiling speaker system provides the combination of excellent pattern control, wide bandwidth, high power handling, and compact design like the C8.2HC.
EVID™ C10.1
The C10.1 packs a 10-inch subwoofer in a
tuned high performance enclosure to give
amazing low frequency performance down
to 45Hz! It is one of the few quick-mount
ceiling TRUE subwoofers available. Flexible
installation and powerful low-end performance make it the ideal mate to any EVID ceiling model.

The EVID™ mounting system has been
designed so that, if necessary, the installation
can be done from beneath the ceiling. In
some cases with a suspended ceiling grid,
however, it may be easier to access from both
the top and bottom of the ceiling tile during
the installation process. Typical installation
hardware needed for either suspended ceilings or sheetrock ceilings is included. The
ceiling speaker assembly is held in place by
mounting tabs that securely grip the ceiling
material. Input wiring is attached to a removable terminal block connector that can be
pre-wired if necessar y before speaker installation to speed up the installation process.
INSTALLATION NOTE: USE OF OPTIONAL
ROUGH-IN ACCESSORIES
For most installations, no additional hardware is needed. However, a two-step installation procedure that is sometimes used for
installation into sheetrock ceilings can be
made easier by the use of the optional RR
and RPK series of rough-in accessories
before the ceiling material is installed. The
rough-in accessories provide a cutout guide
when many holes are to be made in a production-line style installation and to ensure
the speakers are positioned correctly as the
holes are cut in the sheetrock. Depending on
the requirements, two types of rough-in
accessories are available.
RR Series Mounting Plates
RR series plates are made of flat sheet metal
with holes to attach to the joists or trusses of a
building structure. The holes are drilled for
nails or screws at 16 inches (406 mm), 20
inches (508 mm) and 24 inches (610 mm) oncenter. The installer can drill other holes as
needed up to a maximum of 24-3/4 inches
(630 mm) apart. The sheetrock installs over
the plate, and the plate provides a template for
a blind cutout of the hole in the sheet rock.
The ceiling material is generally cut with a
router-type cutting tool, using the plate ring as
a cutout guide. The mounting plate is illustrated in Figure 4.
RPK Series Kits
The RPK series rough-in kit contains a RR
series plate with a standard 2 gang electrical
box mounted on the top with an attached
short length of flexible conduit which connects to the ceiling speaker conduit clamp on
the speaker’s rear terminal cover. This accessory allows for rigid conduit to be run to the box
on the rough-in plate before the speaker or
any sheetrock is installed. After the sheetrock
is installed the speaker can be wired up and
mounted all from below the ceiling. The RPK
mount system is shown in Figure 5.
INSTALLATION NOTE: CONTROLLING
VIBRATION
Because of their high performance, EVID
ceiling loudspeakers can generate substantial
vibration, which can cause buzzing in loose
sections of the ceiling structure. Depending
on the character of the ceiling tile and related components, dampening material may
need to be used under the tile rails or the
edges of the tiles to eliminate rattles.
