Description

The attractive B Series loudspeaker assemblies offer exceptional sound performance by integrating a full-range 4″ high compliance driver with the convenience and cost-effectiveness of a factory-assembled package. These assemblies feature the renowned Atlas Sound FC104 speaker, celebrated for its superior voice and music reproduction capabilities across a wide frequency range. They provide wide-angle sound dispersion, ensuring optimal coverage in distributed audio systems with fewer speakers needed. Each speaker is equipped with a 10-ounce ceramic magnet and a damped, high-compliance cone for excellent low-frequency reproduction and smooth, extended response.

The package includes a factory-mounted, dual-voltage 70.7/25V or 70.7V transformer, along with a choice of round or square grille options for screw mount or torsion spring (T) installation. Two models come with the innovative EZ-Mount support system, ideal for suspended ceiling tile installations that do not require a protective enclosure. These assemblies come with pre-mounted EZ brackets designed to accept provided EZ mount support rails. The rails can be attached using wingnuts and are adjustable to fit varying ceiling depth requirements, eliminating the need for a tile bridge. Every B Series package is shipped fully assembled and ready for quick installation.
