Elegant and Durable Design with Black Finish

Each Bose FS4SE speaker is crafted with a modern industrial design that complements a wide range of commercial interiors and exteriors. The matte black enclosure and grille blend seamlessly into dark ceilings, walls, or columns, offering minimal visual intrusion while delivering high-quality background and foreground music reproduction.

In addition to its clean visual appeal, the FS4SE loudspeaker features a rugged IP55-rated weather-resistant design, making it suitable for use in outdoor areas where exposure to moisture, dust, and temperature fluctuations is a concern.

Full-Range Sound for Foreground and Background Audio

At the heart of the Bose FS4SE is a 4.5-inch full-range driver capable of reproducing a wide frequency spectrum with excellent clarity and low distortion. This design enables the speaker to handle both music and speech applications with equal precision, making it a versatile choice for distributed audio systems in commercial settings.

With a frequency response of 70 Hz – 16 kHz (-3 dB), the FS4SE provides rich midrange detail and crisp high frequencies, while maintaining consistent tonal balance across the coverage area. The speaker is optimized for open spaces that require articulate audio without needing additional subwoofers or tweeters in every zone.

Wide 125° x 125° Dispersion for Even Coverage

Thanks to its 125° conical dispersion pattern, the FreeSpace FS4SE delivers wide, even sound coverage across rooms and outdoor areas. This broad dispersion ensures that fewer speakers are needed to effectively cover large spaces, which reduces system complexity and installation time.

The speaker’s coverage pattern ensures that customers, guests, or visitors hear the same balanced sound regardless of their position in the room or outdoor zone—eliminating hot spots or dropouts that can affect audio quality and listener experience.

Weather-Resistant for Indoor and Outdoor Use

The IP55 rating confirms that the Bose FS4SE black pair is built to withstand dust, water, and harsh weather conditions, making it ideal for semi-exposed or outdoor environments. The enclosure is constructed with durable ABS plastic, while the grille and hardware are designed to resist corrosion, UV exposure, and temperature fluctuations.

From poolside lounge areas to open-air shopping malls and restaurant terraces, these loudspeakers maintain their performance and appearance over time, offering peace of mind to facility managers and integrators.

Flexible Mounting and Fast Installation

Each FS4SE speaker comes with a matching wall-mount bracket that enables quick and secure mounting. The bracket allows for rotational aiming to direct the sound precisely where it is needed. Whether installed horizontally or vertically, the FS4SE adapts easily to a wide variety of surfaces, including walls, columns, and beams.

The speaker’s compact footprint also means that it can be installed in tighter or more visually sensitive areas without distracting from the overall design of the space. An internal safety attachment point allows for secure secondary restraint, ensuring compliance with commercial safety regulations.

Transformer Tap Settings for Distributed Systems

The FreeSpace FS4SE is designed for commercial distributed audio systems and features a built-in 70V/100V transformer for use in multi-zone setups. A rear-mounted rotary tap selector allows the installer to choose from a variety of power settings, depending on room size, layout, and desired volume output.

The available tap settings include:

• 70V: 30W, 15W, 7.5W, 3.75W

• 100V: 30W, 15W, 7.5W

• 8-ohm bypass for low-impedance operation

This makes the FS4SE compatible with a wide variety of commercial amplifiers and control systems, providing maximum design flexibility.
