Low-profile in-ceiling speakers

Bose DesignMax DM6C in-ceiling speakers can be installed overhead in a large, open space, and they offer a solid option for background music and announcements. Each features a 6-1/2" woofer and a coaxially mounted 1-1/4" neodymium dome tweeter. A 145° conical dispersion pattern helps you get maximum coverage with relatively few speakers.

Designed for performance

The new DesignMax Series offers some helpful perks when it comes to audio performance. Dispersion Alignment System technology ensures optimum blending of high, mid, and low frequencies throughout the speaker's listening area. And custom Bose-designed drivers deliver flat frequency response without the need for additional DSP or EQ processing.

More benefits of DesignMax

DesignMax in-ceiling speakers offer faster, safer installation. The enclosure includes QuickHold spring-loaded mounting arms that hold the speaker in place so your hands are free to finish the installation. They also blend into your decor, with minimum-bezel grilles and a removable Bose logo. An adjustable tile bridge is included. When installing in new construction, a Bose rough-in kit (not included) can help you mark speaker locations.

Part of a customizable Bose system

The Bose DesignMax product line includes speakers that fit in different spaces but are designed to work together.

Our system designers can help you choose the right mix of products to customize a system that sounds amazing in your unique space.

Product Research


Overview: The Bose DesignMax DM6C is a high-performance, 70/100 volt, in-ceiling loudspeaker that has been designed for foreground music and speech reproduction in a wide range of installed applications, such as performing arts centers, houses of worship, retail stores, conference centers, hospitality venues, and more. The front baffle is made from durable ABS plastic, with a powder-coated, perforated metal grille, and is housed in a steel backcan. The DM6C features a 6.50" woofer with a coaxially mounted 1.25" tweeter, all mounted in a ported enclosure that can deliver high output with 145˚ of conical coverage and a frequency range down to 59Hz.

Shared Voicing: Shared voicing across the entire product line allows Bose DesignMax loudspeakers to be integrated into the same system while maintaining consistent tonal quality.

70/100 Volt: The DM6C is rated for 100 watts RMS (400W peak) and can be used with both 70 and 100 volt systems. The in-ceiling speakers include an 8Ω bypass mode as well. An easy-to-change dial on the face of the speaker allows tap settings to be made without having to remove the speaker from its mount. The following tap settings are available:

  • 70 V: 2.5W, 5W, 10W, 20W, 40W, and 80W
  • 100 V: 5W, 10W, 12W, 20W, 40W, and 80W
  • 8Ω: Bypass

Connections: The DM6C features a 6-pin Euroblock (Phoenix) connector for attaching speaker wire. Each Euroblock terminal can accommodate wire from 18 AWG to 14 AWG and is accessible from the front of the speaker, allowing it to be wired while mounted. Each speaker's Euroblock connector includes a set of Output terminals for "daisy-chaining" multiple speakers. The 6-pin Euroblock terminals include:

  • In:
    • 70/100V: Positive (+)
    • 8Ω: Positive (+)
    • Com: Negative (-)
  • Out:
    • 70/100V: Positive (+)
    • 8Ω: Positive (+)
    • Com: Negative (-)

Mounting: The DM6C features Bose's patented QuickHold mounting system that includes three integrated mounting arms that swing outward when tightened from the front of the speaker, supporting the speaker against the back of the mounting surface. The DM6C speaker set also includes tile-rails and tile-bridges for mounting each speaker in drop-ceilings where extra support is necessary.

Grilles: Magnetically mounted grilles are included with the DM6C speakers, providing easy removal and access to the front of the speakers. Each perforated metal grille includes a rotatable logo and safety lanyard, and can be painted to match the surrounding decor.
