The Extron FF 220T is a full‑range ceiling tile speaker designed for use in 70 V or 100 V distributed audio systems, featuring Extron’s Flat Field® Technology to ensure consistent sound levels across the listening area. With extremely wide 170° sound dispersion and a low-profile UL 2043 plenum‑rated enclosure, it's ideal for installation in standard suspended ceilings—especially environments with limited above‑ceiling clearance.
Available in two enclosure sizes—2′ × 2′ (61 × 61 cm) for U.S. systems and 600 × 600 mm for metric grids—each version integrates directly into T-bar ceiling layouts with minimal depth (just 3.25″/8.3 cm). Its discreet white perforated grille blends with HVAC diffusers, optimizing aesthetics and installation simplicity.
