About this Guide
This guide describes the SF 3C LP and SF 3CT LP speakers and provides instructions for
installing all components of the system in different types of ceilings.
NOTE: Observe all applicable building codes and local ordinances when installing the
speaker.
Overview
The SF 3C LP and SF 3CT LP meet stringent UL 2043 requirements for smoke and heat
release in plenum air spaces. The 3-inch (76 mm) full-range driver features a frequency
range of 65 Hz to 20 kHz and a conical dispersion of 165 degrees. The SF 3C LP and
SF 3CT LP feature a thin-edged bezel and a magnetically attached grille.
The SF 3C LP supports 8 ohm operation. The SF 3CT LP supports 70 V, 100 V, and 8 ohm
direct operation. The SF 3CT LP has a 6-position rotary switch for selecting the various
power taps for 70V, 100V, or 8 ohms. The two models are physically similar, with slight
variations in weight and front baffle appearance.
The Extron SoundField SF 3C LP and SF 3CT LP are full-range ceiling speakers with 4-inch
(102 mm) low profile composite back cans for use in plenum rated ceiling environments with
limited vertical clearance above the ceiling.
