The Bose FreeSpace DS 100F loudspeakers deliver high-energy, full-range sound, making them well suited for foreground music applications in retail, restaurant, hospitality and other applications where music and entertainment are key parts of creating a customer experience.

These 100-watt loudspeakers can be easily flush or pendant mounted in ceilings up to 30 feet (10m) high. Fewer loudspeakers are needed to create even coverage due to the high output and even dispersion. Quickly and easily set taps with a simple turn of an innovative thumb wheel accessible under the grille. Clean, sleek styling visually blends into ceilings while providing exceptional presence, full bass and clear detail.

The FreeSpace DS 100F loudspeakers are acoustically compatible with the FreeSpace DS 100SE surface-mount loudspeakers and can be combined on the same loudspeaker line. The DS 100F can be installed quickly and simply due to its integrated mounting arms. This versatile design makes the DS 100F suitable for almost any ceiling installation: flush mounted above the ceiling, pendant mounted in open ceilings or installed in air handling (plenum) spaces.
