Bose Professional DesignMax DM3C Rough-In Kit for DesignMax 3C (6-Pack)

The Bose 829719-0010 is a rough in kit that comes in a pack of six and is built specifically for Bose DesignMax DM3C ceiling speakers. It lets installers lock in speaker placement during the framing stage, so every cutout lines up perfectly once the hard deck ceiling is finished.

If you are running audio wiring on a new build, outfitting a retail space, or modernizing a conference room, this kit removes guesswork. By setting the brackets early, you can pull cable, inspect alignment, and close the ceiling knowing the speakers will drop in quickly during the final trim. The result is a cleaner job site and a professional finish that saves time for electricians, AV integrators, and facility teams.

Because the brackets are matched to the DM3C, the speakers sit flush and secure without extra shims or adjustments. That precision helps preserve acoustic performance and delivers the polished appearance clients expect from Bose systems.
