Introduction
This section gives an overview of the Extron SF 26CT LP SoundField® Low Profile XD 2-way
speaker. Topics include:
• Overview
• Features
• Application Example
Overview
The Extron SoundField® XD model SF 26CT LP is a low profile 6.5” (165 mm) two-way
ceiling speaker featuring a 4.2” (107 mm) deep composite back can for use in restricted
height plenum rated ceiling environments. The driver complement includes a 6.5” (165 mm)
woofer coupled to a 3/4” (19 mm) ferrofluid-cooled dome tweeter. The SF 26CT LP offers
both direct 8 ohm and 70/100 volt operation with a behind-the-grille, six position power
selector switch. With high impedance taps at 8, 16, 32, and 64 watts, the SF 26CT LP is
ideal for applications that require a high power distributed speaker system in smaller plenum
spaces.

Installation in a Suspended Ceiling (Single Installer)
If a single installer is installing the SF 26CT LP speaker system, follow the steps in this
section. Topics in this section include:
• Installation Considerations
• Preparing the Installation Location
• Configuring the Speaker
• Mounting the Speaker
Installation Considerations
WARNING: Potential risk of severe injury. Installation and service must be
performed by authorized personnel only.
AVERTISSEMENT : Risque potentiel de blessure grave ou de mort. L’installation et
l’entretien doivent être effectués par le personnel autorisé uniquement.
• 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.
Preparing the Installation Location
1. Power down all attached devices before proceeding.
2. Ensure that there is sufficient clearance above the ceiling tile for the unit to be installed.
3. Cut a hole for the 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 step3b.
d. Using the provided cutout template, trace a circle around the
cutout template.
e. Cut out the circle traced on the ceiling tile.
f. Replace the tile in the ceiling.
SF 26CT LP User Guide • Installation - Single Installer 3
4. Attach two V-rails and one C-ring across the tile above the hole cut in step 3, as shown
V
C-ring
below:
a. Assemble two V-rail half sections as follows: fit the tab of one end into the slot of
the other end, then open the V-rail until it locks together (see figure 2). Repeat this
procedure for the other V-rail.
Figure 2. Assembling the V-rails
b. Remove a ceiling tile adjacent to the tile with the hole.
c. Place both assembled V-rails on the cut ceiling tile and position them equally on
either side of the hole. The ends of the V-rails go over the ceiling grid.
d. Position the C-ring assembly on the two V-rails so that the C-ring is centered over
the hole, as shown below.

Figure 3. Positioning the C-ring Assembly on the V-rails
e. Secure the C-ring to the V-rails using two screws.
5. Route the speaker wires through the ceiling tile hole.
