Family Room

An ideal solution for difficult in-corner media systems. Boston in-ceiling speakers provide a great sound stage in tight or unconventional locations. For a Boston Hidden Theater, install single channel ceiling speakers as Left/Center/Right in the front. Use single channel speakers for directional surrounds in back or use select Boston single speaker stereo models for diffuse sound.


The kitchen is certainly a high traffic area in most households. Add music or connect to an intercom system while saving countertop space. Install a pair of Boston single channel ceiling speakers or just one single speaker stereo model for smaller kitchens.

Workout Room

Many homes now include a dedicated workout space. Adding great sound by installing Boston ceiling speakers will provide the soundtrack to motivate anyone's workout. Install a pair of Boston single channel ceiling speakers or just one single speaker stereo model for smaller spaces.
