Extron FF 120T (part number 42-120-13) — a matched pair of low-profile 1' x 2' drop-in ceiling speakers with onboard 70 V/100 V transformers.

Ceiling loudspeakers usually force a trade-off: hang enough of them to keep levels even, or accept hot spots directly underneath each unit. The FF 120T answers that with Extron's patented Flat Field design, which curbs the mid- and high-frequency beaming that creates those hot spots, and with a 170° conical pattern that spreads output far off axis. Rooms with low ceilings benefit most, since two units can hold coverage where four conventional speakers would otherwise be specified. The pair ships ready to drop into a US-style grid.

Key Capabilities

• Flat Field driver loading holds levels steady across the seating area rather than peaking under each speaker.
• 170° conical coverage from a single 3" (76.2 mm) full-range paper-cone driver.
• Selectable 70 V and 100 V taps at 16 W, 8 W, 4 W, 2 W and 1 W, wired inside the rear panel, plus a null position that bypasses the transformer for 8 ohm operation.
• UL 2043 plenum-rated composite enclosure measuring only 3.25" (8.3 cm) deep.
• 68 Hz to 18 kHz range at 86 dB SPL (1 W, 1 m, half space) with 16 W rms pink-noise capacity.
• Neutral white perforated steel grille that reads as an air vent and discourages tampering.

Where It Is Used

Classrooms and lecture spaces are the obvious fit, and the wide pattern also suits training rooms, conference rooms, waiting areas and other low-ceiling spaces where speech intelligibility matters more than raw output. The plenum listing allows placement in return-air ceiling voids common to commercial and healthcare buildings.
