Boston Acoustics extends the quality you expect to their in-ceiling speakers. You can have home theater sound or music throughout the house without sacrificing fidelity. This speaker installs directly in your ceiling, making them a great choice for rooms without lots of space to spare. Pick up a pair for great stereo sound in the kitchen, laundry room, or den. Plus, you can paint the frame and grille to blend in with your décor.

An NCBR8 in-ceiling bracket is recommended for installing this speaker in a new home under construction or in a room that's undergoing major renovation. (Brackets sold as a pair.)

Product Research


Installation: After a 10-7/8" diameter cutout is made the speaker is installed into the opening and held into place with four integral plastic mounting ears. The required depth to install the speaker is 4-3/8" from the mounting surface (this includes the thickness of the drywall). Behind the opening there must be a 1" clearance around the speaker to accommodate the ears. The mounting wall material must be at least 1/4" thick for the mounting ears to work.

Paintable: Both the frame and grille can be painted to match the ceiling. A plastic paint mask is included to protect the speaker from being painted as well.

Inputs: The speaker clips will accept bare wire up to 14 gauge.

Optional Bracket: The NCBR8 new-construction bracket (sold separately) can be used to simplify installation in new construction.
