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.
