The Extron FF 120T is a full‑range ceiling tile speaker engineered for 70 V / 100 V distributed audio systems. Featuring Extron’s patented Flat Field® speaker technology, it minimizes mid‑ and high‑frequency beaming directly beneath the driver, providing remarkably uniform sound coverage across the listening area and reducing the required speaker count.
Housed in a low-profile UL 2043-rated enclosure (just 3.25″ / 8.3 cm deep), the FF 120T is ideal for plenum airspaces above standard US-style suspended ceilings. It drops directly into a 1′×2′ tile grid and includes an integrated T-bar for secure installation. The white perforated grille blends seamlessly with HVAC vents.
