GENERAL DESCRIPTION
Attractive B Series loudspeaker assemblies combine the sound performance of a full range
4" high compliance loudspeaker with the job site convenience and economy of a factory-
assembled loudspeaker, transformer and baffle. Models incorporate the popular Atlas Sound
FC104 high performance loudspeaker, recognized for full-range voice and music reproduction.
Unit provides wide-angle sound dispersion to achieve desired coverage with fewer loudspeak-
ers in distributed systems. Each loudspeaker employs a 10 ounce ceramic magnet and a
damped, high-compliance cone to provide excellent low-frequency reproduction with smooth
extended response. Package includes factory-mounted, dual-voltage 70.7/25V or 70.7V trans-
former and round or square grille with screw mount or torsion spring (T) installation where
noted. Two models are equipped with the patented EZ-Mount support system. EZB Models are
designed for application in suspended ceiling tile installations which do not require a protective
enclosure. Assemblies include pre-mounted EZ brackets which are slotted to accept EZ mount
support rails (provided). Rails attach with wingnuts and adjust vertically to accommodate
varying ceiling depth requirements (Note: No tile bridge is required). All B Series packages are
shipped assembled and ready for installation.
