C6HTBBX

Sealed back-box enclosure for select MartinLogan in-ceiling speakers. This optional enclosure creates an isolated acoustic chamber behind in-ceiling speakers, improving bass response and preventing sound transmission to adjacent rooms or spaces above the ceiling. Particularly important in commercial installations, home theaters, or multi-family dwellings where sound isolation is critical. The sealed design eliminates the speakers' use of ceiling cavity as enclosure, providing more predictable and controlled bass response. Constructed from durable materials with acoustic properties optimized for MartinLogan in-ceiling models.
