The FreeSpace DS 40F builds upon the Bose core technology of such classic loudspeakers as the FreeSpace Model 32 and 102F by utilizing a 4.5" (114 mm) HVC (Helical Voice Coil) full-range driver. Like these classic products, the FreeSpace DS 40F delivers even frequency response without any crossover abnormalities, and provides a high level of reliability. The new DS 40F driver features design improvements that allow for better sensitivity, higher power handling and greater acoustic output. These improvements allow this loudspeaker to play louder with less distortion. In addition, it does not require active equalization and is voiced to sound similar to the other FreeSpace DS loudspeakers (DS 16, DS 100).
Beyond improvements in performance, the FreeSpace DS 40F features several significant installation improvements and provides more overall flexibility. It features all the same installation methods as the FreeSpace DS 16F and DS 100F loudspeakers. Flush-mount installation is quick and easy, thanks to the three integrated mounting anchors. The loudspeaker can be suspended from open ceilings with a pendant-mount kit accessory. In fact, the DS 40F is compatible with all the same installation accessories as the DS 100F. Its tap can be set from the front of the loudspeaker by turning a thumb wheel. And it is available in both black and white.
