Description

Features

Overview: The Bose FreeSpace DS  40F is a high-performance 70/100 volt loudspeaker that can be either ceiling or pendant mounted (indoor only) and has been designed for foreground music and speech reproduction in a wide range of installed applications. Made from durable ABS plastic with a powder-coated metal grill, the DS 16F features a 2.25″ full-range driver mounted in a ported enclosure that can deliver high output with 140˚ of conical coverage and a frequency range down to 80 Hz.

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.

70/100 Volt: The DS 16F is rated for 16 watt RMS (64 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 underneath the metal grill allows tap settings to be made without having to remove the speaker from its mount. The following tap settings are available:

• 70 V: 1 W, 2 W, 4 W, 8 W, and 16 W
• 100 V: 2 W, 4 W, 8 W, and 16 W

Connections: The rear of the DS 16F has three set-screw terminals for speaker wire connections that can accommodate wire from 18 AWG to 14 AWG. A screw-down protective cover plate is provided that also includes a ring for an optional safety cable attachment.

Mounting: The DS 16F includes three integrated quick-install mounting arms that swing outward when tightened, supporting the speaker against the back of the mounting surface. The speaker’s enclosure also has three mounting points on the backside that can accommodate an optional pendant mount kit (sold separately).
