Bose Professional Retrofit Kit for FreeSpace FS2C Loudspeaker (Black)

The Bose 842864-0110 is a retrofit kit created for installers who need a smooth way to mount or upgrade FreeSpace FS2C ceiling loudspeakers. Whether you are replacing older DS16F units or adding FS2C speakers to an existing grid, this kit gives you the parts and flexibility to finish the job without recutting ceiling material or compromising on fit.

Inside the box you will find two tile bridge rings, two sets of support rails, along with both narrow and wide retrofit rings. The narrow ring handles standard FS2C openings, while the wide ring matches the larger cutout used by the DS16F, letting you swap speakers in minutes instead of hours. All pieces are sized for common acoustic ceiling tiles and can also be secured to hard ceilings when a tile grid is not available.

Each component is clearly dimensioned: rails extend 25.35 inches and sit 10.43 inches apart to spread weight evenly; the tile bridge ring measures 9.8 inches in diameter for solid backing; the narrow ring spans 6.3 inches inside and 9.41 inches outside, while the wide ring keeps the same inner opening but widens to 12.99 inches on the outside. The full kit weighs less than two pounds, so working overhead is manageable even on longer installation days.

Contractors, facility managers, and AV integrators will appreciate how this kit shortens project timelines in retail stores, offices, classrooms, and hospitality venues. By matching existing cutouts and providing rigid support, it helps ensure that FS2C loudspeakers sit flush, stay secure, and deliver the sound quality clients expect from Bose.
