1-inch titanium coated tweeter; and the
EVID C10.1, a true ceiling-mounted subwoofer

designed to augment and extend the
full-range model’s low-frequency response.

Important Features

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
8-inch 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 flush-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 low­profile 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 patent­pending 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 45 Hz! 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.

Product Feature Identification

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 pre­wired if necessary 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) on-center. 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.
