The FreeSpace DS 40SE builds upon the Bose core technology of such classic loudspeakers as the FreeSpace Model 32SE by utilizing a 4.5" (114 mm) HVC (Helical Voice Coil) full-range driver. Like this classic product, the FreeSpace DS 40SE delivers even frequency response without any crossover abnormalities, and provides a high level of reliability. The new FreeSpace DS 40SE driver features design improvements that allow for better sensitivity, higher power handling and greater acoustic output. These improvements allow the DS 40SE to play louder with less distortion. In addition, the DS 40SE does not require active equalization and is voiced to sound similar to the other DS loudspeakers (DS 16, DS 100).
Beyond performance improvements, the FreeSpace DS 40SE features several significant installation improvements and provides more overall flexibility. It features all the same installation methods as the FreeSpace DS 16S, DS 16SE and DS 100SE loudspeakers. Surface-mount installation is quick and easy thanks to the 1→2→3 installation process. It can be mounted to walls, junction boxes, ceilings and poles with optional accessories. In fact, the FreeSpace DS 40SE is compatible with all the same installation accessories as the FreeSpace DS 16S, DS 16SE and DS 100SE loudspeakers. The loudspeaker tap can be set from the front of the loudspeaker by simply turning a thumb wheel. No tools are required.
