Bose Professional FreeSpace FS4CE In-Ceiling Loudspeakers (Pair)

Bose Professional FreeSpace FS4CE is an in-ceiling loudspeaker system designed for indoor and outdoor commercial installations. It enables background music playback and voice announcements for system designers and integrators, supporting distributed audio workflows. This makes it ideal for public and commercial spaces where consistent coverage and environmental durability are critical.

The loudspeakers operate using a full-range transducer housed in an integrated backcan enclosure. They support low-impedance operation as well as 70V and 100V distributed systems through selectable transformer taps. The enclosure and components are engineered to maintain functional operation in wet and outdoor-rated installations.

The system supports applications that require ceiling-mounted loudspeakers with wide dispersion and consistent tonal balance. It is suited for retail, hospitality, transportation, and public safety environments. The design allows integration with other FreeSpace FS loudspeakers for uniform system voicing.
