Overview: The Bose FreeSpace DS 40SE is a full-range, surface-mount, 70/100 volt loudspeaker designed for foreground and background music as well as speech reproduction in a wide range of installed applications such as restaurants, retail stores, houses of worship, and more. The DS 40SE consists of a single 4.5" full-range driver in a ported enclosure that can be surface-mounted vertically or horizontally giving it a 125˚ x 125˚ coverage pattern and a frequency response that goes down to 70 Hz.
70/100 Volt: The DS 40SE is rated for 40 watt RMS (160 peak) and can be used with both 70 and 100 volt systems and includes an 8Ω bypass mode as well. An easy-to-change thumb wheel allows tap settings to be made without having to remove the speaker from its mount. Accessing the tap dial is done by un-snapping one end of the front grill trim. The following tap settings are available:
- 70 V: 2.5 W, 5 W, 10 W, 20 W, and 40 W
- 100 V: 5 W, 10 W, 20 W, and 40 W
Shared Voicing: Shared voicing across the entire FreeSpace DS product line allows the DS 16, DS 40, and DS 100 loudspeakers to be integrated into the same system while maintaining consistent tonal quality.
Mounting: Bose offers a versatile mounting system with the DS 40SE. The built-in rear mounting bracket can be rotated 90˚ by removing four screws, allowing the speaker to be mounted horizontally or vertically. The mounting bracket allows up to 45˚ of tilt or swivel, depending on how the speaker is aligned, and the Bose logo can also be rotated to match the speaker orientation. All wiring for the speaker is attached to set-screw terminals inside the wall-mount plate. A single 4-pin connector cable on the speaker plugs into a socket on the wall-plate, giving the speaker a clean look and allowing it to easily be detached and re-attached to the mount. Two threaded fasteners are provided to hold the speaker to the wall-plate (only one is needed), one with a standard P2 Phillips-head and one with a 3 mm pin-in-hex head. This is a tamper-prevention fastener that requires a specific tool to remove (sold separately). An M4 x 14 mm socket is provided on the back of the speaker for an optional safety chain.
