Rough-in kit for 8" ceiling speakers

This rough-in kit is designed for 8-inch in-wall and in-ceiling speakers and ships as a pair for stereo or multi-room setups. It is intended for installers and homeowners running cable during new construction or major renovation. The kit provides a secure mounting platform before drywall goes up, helping the finished speaker sit flush and level. It suits anyone who wants a professional-grade bracket system without fabricating custom mounts.

Sustained installation reliability

The anti-rust aluminum wings resist corrosion over long periods inside ceiling cavities, maintaining structural integrity through seasonal humidity changes. Wings can be trimmed to the exact joist spacing required, then fastened with staples, nails or screws for a rigid hold that does not loosen. The ring brackets allow 360 degrees of positioning, so the speaker cut-out aligns precisely even when joists are irregular. The assembly meets and exceeds building codes, giving inspectors no reason to flag the installation.

Straightforward mounting

Drywall installers can easily spot the perforated wings and cut around them, reducing errors during the finishing stage. The kit works with Earthquake Turn-N-Lock mechanisms, letting the speaker module lock into the bracket with a simple twist once the ceiling is closed. No special tools are needed beyond basic framing hardware, and the thin wing profile keeps the assembly low-profile against joists. The only limitation is that the kit fits 8-inch speakers exclusively; other diameters will require a different rough-in bracket.
