AtlasIED 191-78-8 Extra Deep Enclosure with Adjustable Mounting Bracket

Optimize sound performance and installation flexibility with the AtlasIED 191-78-8 extra deep enclosure — a professional-grade enclosure designed to enhance low-frequency response and minimize resonance for commercial speaker systems. This AtlasIED enclosure features a generous internal volume and a 1 1/2" high-density fiberglass lining that acoustically loads 8" diameter loudspeakers, delivering fuller, richer bass and cleaner mid/high detail. Constructed from heavy-gauge CRS with a rust-preventive textured black finish, the recessed mount backbox (11-11/16" depth) reduces metallic ringing for more reliable monitoring and public-address performance.

Installation is faster and more secure thanks to the adjustable mounting bracket and two included mounting rails, plus four combination conduit knockouts for flexible wiring. TAA and NDAA compliance make this enclosure a strong choice for government, transit, retail, and security installations where durable, code-compliant components are required. Ideal for AV, security, surveillance, and monitoring rooms that demand high-quality audio, the 191-78-8 integrates seamlessly into professional systems. Specify the AtlasIED extra deep enclosure for your next commercial or security audio project and experience tangible improvements in bass response and installation efficiency.
