Crestron SPKA-BBFR Fire Rated Back Boxes for In-Wall and In-Ceiling Speakers

Cutting a speaker into a rated wall or ceiling breaks the assembly unless something behind it restores the rating. These back boxes do that, and they also stop sound crossing between rooms through the plenum, which is the other reason to specify one.

Order the box by the speaker it serves: the BBFR8 for the IC6 and IC8 in-ceiling models, the BBFR4-IW4X8 for the Reference in-wall, and the BBFR4-IWLCR62 for the Ultimate LCR in-wall. Each is supplied singly, so count one per speaker.
