Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Overview: The Russound speaker back box is made of a proprietary
composite material, and offers an innovative acoustic barrier that will reduce
background noise, provide a moisture barrier, diffuse distortion, and improve
sound quality for your in-wall speakers. It is flame retardant, and is sized
to fit between the studs in 3.5" deep bays. It should be used for new construction,
and is not designed for retrofit installations.
Speaker Wire: The back box does not provide a slot or hole for speaker
wire. You must cut a small hole or slit in the material, and insert the wire.
Flame Retardant Standards: The speaker back box is flame retardant,
and meets the ASTM E119 and UL 263/NFPA 251 (1-hour) and ASTM E84/NFPA70
standards. For fire rated installations, the hole where the speaker wire comes
through should be sealed with fire-rated caulk (3M's Fire Barrier Sealant FD150+
or FD200+ is recommended.) Coating around the edge of the drywall side of the
box is not required, but could be added to create a strong acoustic seal.
