The Extron FF 220T is a full-range ceiling tile speaker for 70 volt/100 volt systems. The FF 220T 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 220T offers an extraordinarily wide dispersion of 170 degrees, providing a very wide room coverage pattern for rooms with low ceilings. An Extron exclusive, UL 2043 plenum rated enclosure drops into suspended ceilings, providing quicker installations. Two versions are available: a 2′ x 2′ version for US standard ceilings and a 600 mm x 600 mm version for metric ceilings. Both versions feature a low profile, 3.25″ (8.3 cm) enclosure 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 220T to reduce beaming of mid and high frequencies directly under the speaker, delivering consistent sound levels across the listening area. Extremely Wide Sound Dispersion The FF 220T 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, fewer FF 220T speakers are required for a given room, as compared to 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 microphone and program material applications. The FF 220T provides excellent voice clarity without compromising music reproduction. The FF 220T 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 220T drops into the same space as a standard US or metric ceiling tile, and includes a T-bar for 2′ x 4′ ceilings or 600 mm x 1200 mm ceilings. It also provides theft deterrence with a neutral white, perforated steel grille that matches the appearance of standard air conditioning vents and grid ceilings.
