Foam back-box enclosure for most in-wall speakers
The FB-W enclosure is a flexible, pre or post-construction rectangular acoustic foam box. Designed for in-wall speakers (see full compatibility list below), the FB-W provides a better enclosed environment for the speaker, thereby improving sound quality while also reducing sound transfer into other rooms. The FB-W can be mounted in-between standard 2x4 stud-framed walls during construction, or for post-construction installation, simply fold the FB-W lengthwise, push it through the speaker’s mounting hole and expand it into place inside. Once the FB-W is in place, just tack it to the framing.
The FB-W works with the following speaker models: VA-414, VM-414, VA-610, VM-610, VM-616, & VM-553.
