transformer, and baffle. Models incorporate the popular Atlas Sound FC104
high performance loudspeaker, rec og nized for full-range voice and music
reproduction. Unit provides wide-angle sound dispersion to achieve desired
coverage with fewer loud speak ers in distributed systems. Each loud speaker
employs a 10 ounce ceramic magnet and a damped, high-compliance cone
to provide excellent low-frequency reproduction with smooth extended
re sponse. Pack age includes factory-mounted, dual-voltage 25V/70.7V or
70.7V trans former and round or square grille with screw mount or torsion
spring (T) installation where noted. One model is equipped with the
patented EZ-Mount support system. EZB Model is designed for application
