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.
