AtlasIED TR411 4" Ceiling Speaker Mounting Ring for Drywall

The AtlasIED TR411 is a new-construction mounting ring designed for integrators and installation crews placing 4-inch torsion-spring ceiling speakers in drywall, plaster, or conventional ceiling assemblies. Compatible with AtlasIED T51-4, T710-4, T720-4(BT), and T730-4W(B) baffles, it provides a reliable, cost-effective rough-in solution where a protective back enclosure is not required by the specification.

Unlike open-cut rings that rely solely on ceiling material for support, the TR411 includes mounting ears engineered for direct attachment to 16-inch or 24-inch on-center studs, giving installers a secure mechanical anchor in new-construction framing before drywall is finished. The cold-rolled steel body with black epoxy finish resists corrosion and blends cleanly into finished ceiling surfaces once the grille is seated.

For commercial installs, hospitality, retail, and house-of-worship projects where budget and schedule matter, the TR411 eliminates the cost of a full back-can while maintaining a professional, code-conscious rough-in. It ships at a low weight, making it practical to stock in quantity for multi-zone distributed audio projects.
