The Federal Signal Model AM15 is a rugged, re-entrant speaker for use in public address or paging applications. This 15 watt speaker features a rugged speaker cone and projector constructed of spun aluminum. The speaker wiring connections are enclosed in a dust- and moisture-proof, die-cast aluminum compartment. All external surfaces are sealed with gray powder coat paint.

Two screws inserted through the back of the wiring compartment provide for simple wall mount installation. The bottom of the AM15 contains two 1/2-inch conduit openings to accommodate inbound and outbound audio wiring. The unique shape of the AM15 projector provides a 60º sound dispersion. The projector is held in position with a Teflon coated lock ring that can be rotated 180º in order to obtain the desired sound distribution.

The AM15 is rated for indoor and outdoor use. This speaker is UL Fire Listed.

The AM15 can be used with the AudioMaster® CTS series amplifiers and the AudioRouter™ to complete an industrial grade public address system.
