The Extron SF 3CLP is a low-profile coaxial ceiling speaker designed for installations where minimal protrusion below the ceiling is required. It features a 3.5-inch (89 mm) full-range driver with a coaxially mounted high-frequency element in a shallow metal back can, delivering clear speech intelligibility and balanced background music with a frequency response of 120 Hz to 20 kHz and wide dispersion. The integrated 70/100 V transformer provides multiple power taps up to 8 W, plus an 8-ohm bypass for low-impedance systems, making it compatible with Extron amplifiers or standard commercial audio setups.

The UL 2043 listed plenum-rated construction ensures compliance for air-handling spaces, while the extremely low-profile design (only 3.9″ / 99 mm deep) and magnetically attached paintable grille allow discreet installation in drop ceilings with limited plenum depth. The included C-ring and tile support rails simplify secure mounting in standard 2×2 ft (610×610 mm) or larger ceiling grids. Ideal for classrooms, conference rooms, hallways, open offices, retail spaces, and other environments requiring high-clarity paging or background audio with minimal visual impact.
