About this Guide
This guide describes the Extron CS 1226T Plus Speaker System, the CS 26T Plus 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 Plus system features a low profile design that houses a 6.5-inch woofer
and a 0.75-inch tweeter (CS 26T Plus) 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 Plus 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 Plus can be installed by the AV systems contractor.

Application Example
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 Plus is UL 2043 listed (only when the CS 26T Plus 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 Plus can be used without the
CS 120P by reconfiguring the attached bass port plate (allowing the CS 26T Plus to
function as an open back speaker).
NOTE: When the CS 26T Plus is used without the CS 120P, it is not suitable for air
handling spaces and is not UL 2043 rated.
Low profile enclosure — The low profile enclosure is compatible with plenum
environments where overhead space may be limited.
