Product Overview

SF 28PT is a high-power 2-way pendant ceiling speaker from Extron, designed for large spaces with high ceilings or open architecture.
With an 8-inch woofer and dome tweeter, it delivers full-range sound with significantly improved low-frequency performance compared with smaller models.
The pendant design allows the speaker to be suspended at an optimal position for even sound distribution in shopping malls, restaurants, large lobbies, and public areas.
Its modern form factor blends easily with interior architecture without affecting the overall aesthetics.
With support for 70V/100V and 8-ohm systems, SF 28PT provides high flexibility for different deployment needs.
It is an ideal solution for background music, paging, and large-scale commercial audio systems that require powerful sound, even coverage, and easy installation in open spaces.
