About this Guide
This guide describes the Extron CS 1226T Speaker System, the CS 26T speaker pair and
the CS 120P enclosure and provides instructions for installing all components of the system
in different types of ceilings.
Overview
The CS 1226T system features a low profile design that houses a 6.5-inch woofer and a
0.75-inch tweeter (CS 26T) contained in a UL 2043 rated enclosure (CS 120P) designed for
use in plenum rated ceiling spaces.
This unique speaker system splits installation into two phases, rough-in and finish, allowing
the installer to “reserve” space for the speaker system by installing the CS 120P back can
and then later installing the CS 26T speaker. This two-step process (division of labor) is
especially useful when multiple installers are involved. The CS 120P can be installed by the
low voltage contractor while the CS 26T can be installed by the AV systems contractor.
Features
•
US and metric ceiling grids — The CS 120P enclosure can be installed in both U.S.
and metric ceiling grid systems (for metric systems, the CS 120P end tabs are cut off).
•
UL 2043 listed — The CS 1226T is UL 2043 listed (only when the CS 26T is used with
the CS 120P).
NOTE: The use of any other back can other than the CS 120P or those provided by
Extron voids the UL 2043 rating.
•
Optional open back configuration — The CS 26T can be used without the CS 120P
by reconfiguring the attached bass port plate (allowing the CS 26T to function as an
open back speaker).
NOTE: When the CS 26T is used without the CS 120P, it is not suitable for air
handling spaces and is not UL 2043 rated.
•
New dog-leg design — The new dog-leg design eliminates jamming during
installation.
•
Low profile enclosure — The low profile enclosure is compatible with plenum
environments where overhead space may be limited.
CS 26T and CS 120P User Guide • Introduction

•
Selectable taps — The rotary tap selector switch, located behind the grille, sets the
speaker to operate in either 8-ohm direct or 70 volt /100 volt operation with 16, 8, 4, 2,
and 1 watt taps.
•
Magnetic grille — Magnets spaced around the grille edge enable it to be easily
attached and to remain firmly in place.

Installation Considerations
WARNING: Risk of severe bodily injury from falling or sharp equipment.
Installation and service must be performed by authorized personnel only.
•
All wiring and electrical connections must conform to all applicable building codes and
local ordinances.
•
Installation in a plenum-rated environment requires plenum rated cable or conduit.
•
If using secondary support cables, the installer provides the cables.
Installation Configurations
The CS 26T can be configured in the following ways:
•
Open-back: For configurations in which the CS 120P is not used, use the C-ring
accessory, available at www.extron.com. The C-ring spreads out the clamping force of
the dog-legs when used in drop ceilings and gypsum ceilings.
•
Using the CS 120P: When used with the CS 120P, the CS 26T can be placed in
plenum environments. This is the only configuration that is UL 2043 rated.
NOTE: The CS 120P can be ordered separately or as part of the CS 1226T kit.
For hard ceiling installations, see Installing the CS 120P in a Hard Ceiling on
page 26.

1. Disconnect power ­— Power down all attached devices before proceeding.
2. Verify the space where the system will be installed ­— Ensure that there is sufficient
clearance above the ceiling tile for the unit to be installed.
3. Cut a hole for the CS 26T speaker — Use the provided cutout template to outline
the hole to be cut in the ceiling tile as described below.
a. Remove the ceiling tile.
b. To find the center of the tile, use a tape measure to measure the space between
two opposite corners, and mark the half-way point.
c. Position the center hole of the cutout template directly over the center of the tile
that you marked in step 3b.
d. Using the provided cutout template, trace a circle on the ceiling tile as follows:
For installations in ceiling tiles that are NOT fiberglass or when installing
the speakers in an open back configuration: Trace a circle around the CS 26T
cutout template.
NOTE: The fiberglass tile adapters are not needed and can be discarded.
For installations in 1-inch (0.25 cm) thick fiberglass ceiling tiles with the
CS 120P:
NOTE: A set of fiberglass tile adapters is provided with both the CS 26T and
the CS 120P. Only one set is needed to install the CS 26T with the CS 120P
kit in a 1-inch (0.25 cm) thick fiberglass tile. The adapter works only with
1-inch (0.25 cm) thick fiberglass tile.
i. Place the fiberglass tile adapter around the outer diameter of the template that
