MartinLogan MC6-HT Retrofit Backbox

All Motion CI in-ceiling speakers have the option for a retrofittable back can or enclosure. This helps contain the sound coming off the back of the speaker to dramatically reduce unwanted sound that can travel through the floor and up into the living space above the speaker. For those desiring increased bass output, or for when sound control is not required, you can simply choose to use the MC6-HT without the optional enclosure so it can take full advantage of the larger air volume provided by the space in the ceiling.
