FB-W28 Page Banner


The FB-W28 enclosure is a flexible, pre- or post-construction rectangular acoustic foam box. Designed for in-wall speakers (see full compatibility list below), the FB-W28 provides a better enclosed environment for the speaker, thereby improving sound quality while also reducing sound transfer into other rooms. The FB-W28 can be mounted in-between standard 2x4 stud-framed walls during construction, or for post-construction installation, simply fold the FB-W28 lengthwise, push into the speaker’s mounting hole in the wall, and it will expand inside. Once the FB-W28 is in place, just tack it to the framing.

The FB-W works with the following speaker models: A-414, A-610, A-616, A-810, MC-414, MC-6, MC-616 and MC-6DB. It WILL NOT work with the following speaker models: MC-553, MC-83, MC-884 and
