Boston Acoustics builds their HSi-series for people who love great sound but not the clutter of speakers. Movie dialogue sounds clear and the notes of woodwinds, strings and brass have a natural tone. Boston Acoustics also designs all their in-wall and in-ceiling speakers for simple do-it-yourself installation. The HSi-250 mounts flush in the ceiling and comes with a magnetic grille that's paintable to blend seamlessly into your home.

An NCBR5 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 6-3/4" 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 3-1/16" 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.

Magnetic Grille: The grille is magnetically mounted for easy installation.

Optional Bracket: The NCBR5 new-construction bracket (sold separately) can be used to simplify installation in new construction.
