B51-4

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 AtlasIED FC104 high performance loudspeaker, recognized for full-range voice and music reproduction. Unit provides wide-angle sound dispersion to achieve desired coverage with fewer loudspeakers 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 25V/70.7V or 70.7V transformer 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 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.
