Product Overview
SF 8CT SUB is an in-ceiling subwoofer from Extron, designed to extend low-frequency performance for ceiling speaker systems in commercial and professional AV environments.
With an 8-inch driver and bass-reflex design, it delivers deep, tight, and clear bass to significantly improve overall audio quality, even when paired with smaller ceiling speakers.
The speaker supports both 70V/100V and 8-ohm systems, enabling flexible deployment from distributed audio systems to higher-power configurations.
An integrated 120Hz low-pass filter simplifies system setup without requiring an external crossover.
With its clean in-ceiling design, plenum-rated construction, and scalable deployment capability, SF 8CT SUB is an ideal solution for offices, meeting rooms, retail spaces, restaurants, and commercial audio systems that require enhanced bass performance while maintaining a clean and aesthetic environment.
