RBH Sound rear enclosures are a flexible, pre or post-construction acoustic foam box. The rear enclosures are specifically designed to provide a better enclosed environment for our in-wall speakers, improving sound quality while also reducing sound transfer into other rooms. Rear enclosures can be mounted in-between standard 2x4 stud-framed walls during construction, or for post-construction installation. Simply fold the flexible rear enclosure, push it through the speaker’s mounting hole, and it will expand inside the ceiling. Once in place and with the speaker installed gravity along with the insulation will easily keep the rear enclosure in position.
