evōQ™ 3000 In-Ceiling and In-Wall
Speakers

IS-0242 Rev. D

1. Introduction

On-Q/Legrand offers both in-ceiling and in-wall styles of
evōQ™ 3000 speakers. These two styles encompass two

(2) sizes and five (5) part numbers (as shown in Figure 1

to the right). The speakers are optimized for audio
distribution (central sound). All models are 2-way speakers
that feature Mica-Fiber woofers and PEI (Polyetherimide)
Mylar tweeters. These speakers come with dual templates
with center markings and paint rings. Optional speaker
pre-construction brackets are available for all models.

(*P/N MS3652, 6.5” In-Ceiling Dual Voice Coil Speaker, is
for reference only and NOT part of this instruction sheet.)

Disclaimer: Make sure you are in compliance with local
building codes before installing these speakers. On-Q
evōQ™ 3000 In-Wall and In-Ceiling Speakers are
suitable for moisture rich environments such as
bathrooms, saunas and outdoor applications.

2. Description

The On-Q/Legrand evōQ™ 3000 speakers are made of a tough semi-flexible plastic frames that feature a
built in foam gasket to minimize vibration and maximize seal-ability. They also feature a perforated metal grill
with an acoustically transparent scrim cloth to enhance the speakers appearance once installed
speakers, except sub woofers, are paint-able. They also come with painting shields to protect the drivers
while painting. These speakers are suitable for moisture rich environments. They also feature flip out tabs for
easy installation and removal.

3. Installation

Installation of the evōQ™ 3000 speakers is best accomplished at multiple times during new construction, at
“Rough-in” before the drywall is installed, and at “Trim-out” after the drywall is installed and painted.

A. “Rough-in” steps:

NOTE: It is recommended that a minimum of 16 gauge, 2 conductor wire be
used for most applications from the amplifier or volume control to the speaker.
Different gauges can, and should, be used based upon the distance of the

intended run or quality of installation (see Figure 2).

NOTE: All On-Q/Legrand lyriQ™ Audio components accommodate wire gauges
from 18 to 14.

2. If an On-Q Speaker Pre-Construction Bracket is to be used, skip to

Step “5” and refer to IS-0243 for detailed instructions.

3. If pre-wiring without
Brackets, leave 4 to 6 feet of wire at the speakers intended location.
Use a strip of cardboard stapled to the joints/studs with a hole
through it as a wire place holder for the drywall installers if

installation of the speakers is intended (see Figure 3).

4. After drywall and/or painting is complete, push wire through hole,
center template over hole, mark with a pencil and cut out with a dry­wall knife.

5. When using the On-Q Pre-Construction Bracket (see
Figure 4), leave a coil of speaker wire on top of the

bracket coiled around the speaker mounting hole. There
are clips on the corner of the bracket to secure the
speaker wire. Leave enough speaker wire to be able to
pull the wire through the bracket and comfortably
connect the wire to the speaker after the drywall is
installed. Strip off 3 inches or so of the speaker cable
jacket to expose the positive and negative insulated
wires. Strip 3/8-1/2 inch of insulation off of these
conductors.

6. It is recommended to place insulation behind the
speaker to provide some damping for the woofer driver.
This will yield the best possible sound. On-Q
recommends using poly-encapsulated insulation such as
Johns Manville Comfort Therm®. If a defined, consistent
sound is desired from both speakers in a space, blocking
can be installed to yield the ideal cubic footage for each
driver. Insulation would then be put in this space during
speaker installation. Refer to blocking chart for

details.

7. If installing speakers in a space with an attic above it is
recommended that the speakers be boxed in with 1/2 inch
MDF (medium density fiber board) or plywood with
insulation installed. This will provide a defined acoustic
space and protect the speaker. The best possible sound
will be achieved by doing this. Refer to the blocking

chart for details.

Note: Make sure you are in compliance with local building codes before installing this speaker in
an attic space.
