About the Bose® FreeSpace® DS 100F

Versatile Bose® Foreground Speakers for Your Business

Don't your customers deserve Bose®? Bose products — from headphones to home theater systems — have been customer-pleasing best-sellers for us for decades, so we're happy to be able to extend that same experience to business owners. The FreeSpace® DS 100F speaker offers powerful performance, thanks to a 5-1/4" woofer and 2-1/4" Twiddler® driver. A convenient thumbwheel transformer tap lets you power multiple speakers with a single amplifier.

Build a customizable system to fill your entire restaurant, gym, office, or similar place of business with appropriate foreground or background music and clear, audible announcements.

Multiple Mounting Options

This versatile speaker can be installed in a few different ways. There's a Bose rough-in pan that helps you flush-mount it in drywall. If your business has a drop ceiling, a nifty Bose tile bridge will do the trick. High ceilings? Hang it securely with a Bose pendant mount.

Overview: The Bose FreeSpace DS 100F 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. It features a 5.25" woofer and 2.25" tweeter, mounted in a ported enclosure, that can deliver high output with 160˚ of conical coverage from ceilings up to 32 feet high. The DS 100F's front baffle is made of durable polypropylene with a powder-coated steel grill, housed in powder-coated steel back can enclosure.

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 100F is rated for 100 watt RMS (400 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. The following tap settings are available:

70 V: 12.5 W, 25 W, 50 W, and 100 W
100 V: 25 W, 50 W, and 100 W
Connections: The rear of the DS 100F 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 100F 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 metal enclosure also has three mounting points on the backside that can accommodate an optional pendant mount kit (sold separately).
