The Federal Signal Models AMSF–25 and AMSS–25 are heavy–duty, 8–ohm speakers for use in public address or paging systems. These speakers are designed to reproduce full–range voice communication. Both speakers are constructed of spun aluminum. The speaker wiring connections are enclosed in a dust–tight and moisture–proof, gasketed rear cover. All external surfaces are sealed with a metallic gray powder coat paint.
The AMSF–25 is a flush mount unit that is ideal for use in walls and cabinets. The AMSS–25 has an adjustable mounting bracket that pivots in a 90º arc for attaching to walls, cabinets or vehicle roofs. These speakers are appropriate for marine applications.
The AMSF–25 and the AMSS–25 can be used with the AudioMaster CTS series amplifiers and the AudioRouter™ to complete an industrial grade public address system. These units are also compatible with the Federal Signal SelectFone intercom system.
