Lowell Round Screw Mount Speaker Grille for Ceiling Install | 4" | WB-4

Lowell round screw-mount speaker grilles are designed for integrators and installation contractors outfitting offices, hotels, schools, medical facilities, retail spaces, and commercial buildings with ceiling audio systems. Available in 4-inch and 8-inch speaker sizes, the lineup spans steel and aluminum construction options to match the performance and environmental demands of the install environment.

Each grille ships with the hardware needed to secure it directly to the speaker or enclosure, simplifying ceiling installation across high-volume projects. The contoured edge profiles and white finish options blend into standard commercial ceiling decor without requiring custom finishing. Aluminum variants extend the range to applications where corrosion resistance is a priority, including select outdoor or high-humidity environments where steel construction would be unsuitable.

For integrators specifying a consistent grille aesthetic across a large venue or campus, the family provides a single-source solution covering multiple driver sizes and material grades. The screw-mount design is a recognized industry standard for commercial ceiling speaker installations, making these grilles a practical fit wherever repeatability, clean appearance, and straightforward installation are required.
