Know before you buy
No, this back box is specifically engineered for the Monitor Audio PLIC II in-ceiling speakers. It is designed to provide the precise 24-liter air volume required for that specific model's optimal performance.
This back box is designed specifically for pre-construction installation. Because it must be secured behind the drywall before the ceiling is finished, it is not suitable for retrofitting into an existing ceiling.
An in-ceiling speaker typically relies on the open space behind the drywall, which can lead to inconsistent sound and unwanted vibrations. This back box provides a controlled, rigid acoustic environment that minimizes standing waves and ensures consistent, high-fidelity audio performance.
Yes, the unit arrives with internal damping material pre-installed. This material is essential for absorbing sound reflections inside the enclosure, which helps clarify the audio output.
The back box measures 13.78 inches long, 7.53 inches wide, and 24.75 inches high. You should ensure your joist spacing can accommodate these dimensions and the required 10.79-inch cut-out for the speaker itself.
