Provide 15 watts of continuous power handling with superior intelligibility and efficiency with the Atlas Sound APF-15 Omni-PurposeÂ® loudspeakers. Model APF-15T includes the Vari-TapÂ® Control/ connect center with 7 position, wattage/ impedance selection switch. Magnet assembly is equipped with self-aligning field replaceable diaphragm. Weather-resistant metal construction and enclosed wiring terminals eliminate the need and cost of a backbox. However, for aesthetic consideration and retrofit convenience, models will flange mount to any standard size ceiling or wall baffle and/ or enclosure capable of accommodating conventional 6" or 8" diameter loudspeakers. Recessed installation may be accomplished by mounting Model APF-15T into a 4" or 5.5" deep opening, or to an L20 Series enclosure. L20 Series also includes mounting rings and baffles. Loudspeaker is finished in grey baked epoxy.
