FF 120T Ceiling - 1' x 2' Drop-In, Xfmr, Pair 42-120-13

The Extron FF 120T is a full-range ceiling tile speaker for 70 volt/100 volt systems. The FF 120T features Extron patented Flat Field® Technology which reduces beaming of mid and high frequencies directly under the speaker, delivering consistent sound levels across the listening area. In addition, the FF 120T offers an extraordinarily wide dispersion of 170 degrees, providing a very wide room coverage pattern which is especially important for rooms with low ceilings. An Extron exclusive, UL 2043 plenum rated, 1' x 2' (30.5 cm x 61 cm) by 3.25" (8.3 cm) deep enclosure drops into standard US style suspended ceilings, providing quicker installations. With a low profile enclosure, this speaker is an excellent choice for ceiling installations with tight above-the-ceiling space issues.

Patented Flat Field® Technology

Extron’s patented Flat Field Technology makes this speaker truly unique. Flat Field Technology allows the FF 120T to reduce beaming of mid and high frequencies directly under the speaker, delivering consistent sound levels across the listening area to each student.

Extremely Wide Sound Dispersion

The FF 120T offers an extraordinarily wide dispersion of 170 degrees, which provides a very wide room coverage pattern. This is especially important for rooms with low ceilings.

With the combination of Flat Field Technology and wide dispersion, only two FF 120T speakers are required in a standard classroom, as opposed to four or more traditional ceiling speakers.

This speaker is ideal for use in low ceiling installations for maximum room coverage. This coverage optimizes voice intelligibility, which along with low bass response, is the most critical consideration for classroom microphone and program material applications. The FF 120T provides excellent voice clarity without compromising music reproduction.

The FF 120T offers 70 volt or 100 volt operation and provides power taps for 16, 8, 4, 2, and 1 watt. The power taps are accessed via speaker wiring connections inside the rear panel. The transformer can be bypassed for 8 ohm operation.

For easy installation, the FF 120T drops into the space of a standard 1' x 2' ceiling tile, and includes a T-bar which can be used with a larger ceiling tile trimmed to fill out the space. It also provides theft deterrence with a neutral white, perforated steel grille that matches the appearance of standard air conditioning vents and grid ceilings.
