Bose Professional FreeSpace FS4CE in-ceiling loudspeakers White (1 pair) | 841156-0420

The Bose Professional FreeSpace FS4CE is a pair of flush-mount in-ceiling loudspeakers designed for background music and voice announcement systems in commercial spaces such as retail stores, restaurants, offices, and hospitality venues. The FS series is engineered to provide consistent tonal quality and reliable performance across different installation environments.

Each speaker uses a 4.5-inch full-range driver that reproduces both music and speech clearly across a wide listening area. The speaker’s 115° conical coverage pattern helps distribute sound evenly throughout the room, making it suitable for distributed ceiling audio systems.

The FS4CE supports both 70V/100V distributed audio systems and 8-ohm operation, offering flexibility when designing commercial audio installations. The speaker also includes front-baffle connections and transformer tap adjustments to simplify installation and configuration.

Designed for durability, the FS4CE features a steel back-can and powder-coated grille and carries an IP55 rating, allowing use in outdoor or wet locations when properly installed.
