Lowell Round Torsion Mount Speaker Grille Steel Ceiling Grille | 4" | CN-4M

Lowell's round torsion-mount speaker grilles are engineered for AV integrators and system contractors specifying ceiling audio in commercial environments where visible mounting hardware is unacceptable. The torsion bracket spring mechanism self-retains the grille against the ceiling, eliminating exposed screws and producing a finished architectural appearance. These grilles are the right specification choice for upscale offices, hotels, airports, retail spaces, professional buildings, and dining establishments where aesthetics are as critical as audio performance.

The grille family is available in sizes to fit 4-inch and 8-inch drivers, letting a single product line cover a complete system installation with a consistent finished look. Each grille is constructed from 20-gauge steel with a white finish, making them suitable for standard commercial ceiling environments. The contoured edge profile minimizes projection off the ceiling plane, keeping the installation visually clean. Torsion bracket spring devices accommodate a variety of ceiling depths, providing installation flexibility across different ceiling assemblies without additional hardware modifications.

Compared to screw-fixed alternatives, the torsion-mount design reduces visible fasteners at the ceiling surface and speeds up installation in high-count deployments. Compatible enclosures with torsion receptacles are ordered separately, giving integrators full control over the speaker and enclosure specification while standardizing the grille finish across an entire project.
