INTRODUCTION
The Extron SpeedMount® Ceiling Speaker System is a patented
low profile, plenum rated two-piece speaker system designed for
division-of-labor installations. The innovative CS 1226T SpeedMount
speaker system consists of the CS 120P plenum rated enclosure
and a CS 26T two-way speaker cartridge. The CS 120P enclosure
installs quickly into 2' x 2' or metric 600 mm x 600 mm suspended
ceiling grids. The CS 26T speaker cartridge features a 6.5"
(16.5 cm) woofer and a 3/4" (1.9 cm) tweeter in a coaxial design,
and can be used in 70/100 volt or 8 ohm operation. The CS 1226T
is available as a complete assembly, or the CS 120P and CS 26T
can be purchased separately to accommodate division-of-labor
installations, with the enclosures installed during rough-in and the
speaker cartridges during final installation.

FEATURES
INTEGRATED TILE BRIDGE
Labor and Cost Savings
• No separate tile bridge
• No C-rings
• No tile rails
• No small parts to lose
• Faster install
The CS 120P enclosure features an integrated tile bridge that evenly distributes the weight of the enclosure and the CS 26T speaker cartridge
on the ceiling grid. This avoids the hardware traditionally needed to support conventional ceiling speakers, and reduces associated labor costs.

Many conventional ceiling speaker back cans may not be ideal for ceiling space locations with obstructions such as fire sprinkler piping or
HVAC ducting. The CS 120P features a shallow 5" profile for installation in areas with shallow clearances above the ceiling.

The CS 120P enclosures are
delivered from the factory for
installation into US-style
2' x 2' suspended ceiling grids.
However, the CS 120P is
compatible with metric
600 mm square ceiling grids
as well. All that is necessary is to cut off the sizing
tabs at the ends of the enclosure. The CS 120P can
therefore be specified for a wide variety of worldwide
suspended ceiling standards.

Integrated Tile Bridge
Low Profile Enclosure
The enclosure distributes assembly
weight without the need for C-rings

The 5" (12.7 cm) deep
enclosure is ideal for shallow,
obstructed ceiling spaces with
piping and ducts.
Reinforced Enclosure
Clip-Off Mounting Tabs
Minimizes unwanted vibrations and
prevents acoustic distortion.
The CS 120P can be installed into

INSTALLATION
The innovative, patented two-piece design of the SpeedMount Ceiling Speaker System greatly simplifies installation of ceiling
speakers. Instead of waiting until the final phase of installation, a low-voltage contractor can begin during rough-in by placing
a CS 120P enclosure onto the ceiling grid, and running speaker cable through it. This leaves the AV installer with a simple
procedure of connecting the CS 26T speaker cartridge to the cable and securing it into the ceiling.
During construction rough-in, a CS 120P enclosure is placed into a designated
location on the ceiling grid. Speaker cable is passed through the opening of
the CS 120P, and then the enclosure is secured to the upper ceiling deck.
During final construction, an AV installer connects the speaker cable to the
CS 26T speaker cartridge, using the included captive screw connector.
The CS 26T is quickly secured to the CS 120P enclosure and ceiling tile using
the four spring-loaded locking arms. A power tap selector is conveniently
located on the front baffle edge.
The magnetically attached speaker grille quickly snaps into place inside the
slim bezel, completing the installation and providing a finishing touch.
MODELS
ACCESSORIES
The CS 1226T can be purchased as a complete system, or as
separate components for a division-of-labor installation, so that the
spring-loaded can initially be delivered to a low-voltage contractor,
followed later by the speaker cartridges to the AV integrator.
The CS 26T speaker cartridge can be installed as a standalone
product in non-plenum ceiling spaces. An optional ceiling mount
kit is available to serve as a tile bridge for a suspended ceiling grid
installation.
