Two-Way SoundField Open Back 8 Ohm Ceiling Speakers
The Extron SoundField
®
 SF 26X is a two-way ceiling 
speaker featuring an open back and coaxial dual driver 
design for use in non-plenum airspace environments. 
The driver complement includes a 6.5" (16.5cm) 
woofer coupled to a 3/4" (1.9cm) ferrofluid-cooled 
dome tweeter. The SF26Xprovides a frequencyrange 
of 50Hz to 20kHz for accurate voice and detailed 
music reproduction. This speaker offers a nominal 
impedance of 8ohms, and is engineered with a wide, 
uniform 110° conical coverage and uncoloredoff-axis 
response. The SF26X features a thin-edged bezel for a 
refined appearance on the ceiling, and a magnetically 
attached grille.

Full-Range SpeedMount Ceiling Speaker System
The Extron CS123T SpeedMount
®
 Ceiling Speaker 
System is a patented low profile, plenum rated 
two-piece speaker system. It provides an extremely 
wide 165° conical dispersion for flexibility in speaker 
spacing. The system is designed for applications 
where high intelligibility and maximum coverage 
is desired in paging applications and low ceiling 
installations. The innovative system consists of the 
CS120P plenum rated enclosure and a CS3T full-
range speaker cartridge. The enclosure installs quickly 
into 2'x2' (61cm x 61cm) or 600mm x 600mm 
suspended ceilings. The speaker cartridge features 
a 3" (7.6cm)full-range driver, and can be used in 
70/100volt or 8ohm operation. The CS123T is 
available as a complete assembly, or the CS120P and 
CS3T can be purchased separately to accommodate 
division-of-labor installations. This unique speaker 
design greatly simplifies ceiling speaker installation and 
delivers significant time and cost savings.
