Russound's speaker back box offers an innovative acoustic barrier that will reduce background noise, furnish a moisture barrier, diffuse distortion, and improve sound quality. It is easily installed in both new construction and retrofit settings. The design incorporates a flexible construction with noise-absorbing materials. Both models are flame retardant and meet the following standards: ASTM E119 and UL 263/NFPA 251 (1-hour) and ASTM E84/NFPA 70. The Flexbox back box is sized to fit between the studs with depths of 3.5" (89 mm) for the in-wall enclosures and 6" (152 mm) for the in-ceiling models. As a retrofit solution for in-ceiling speakers, it can be rolled up, inserted through the hole in the drywall, and secured to the studs or drywall prior to installing or re-installing the speaker.
