Abstract
An in-wall or in-ceiling speaker enclosure includes a speaker back box having one or more apertures covered with an air-filtering member (e.g., open cell foam, baffling material, etc.) that may be utilized with speakers mounted on a large baffle (wall or ceiling) for reducing sound transmission to an adjacent room while significantly lowering the resonance of the speaker system and allowing the speakers to produce much greater bass energy into a desired room. Such a speaker back box includes a posterior surface, a plurality of sidewalls engaged with the posterior surface and extending anterior thereof wherein one of the sidewalls includes a first aperture. The speaker back box further includes an anterior opening oppositely disposed from the posterior surface. A flexible and resilient air-filtering member is positioned against the first aperture wherein the air-filtering member is intermediately located between the posterior surface and anterior opening.
