The QSC AC-MR4 is a flanged mud-ring (rough-in) bracket used to pre-install QSC AC-C4T AcousticCoverage ceiling speakers in sheetrock or plaster surfaces. It is an installation accessory, not a speaker. Fitted during construction before the ceiling is finished, the mud ring establishes the cutout and provides a clean, flush edge so the speaker can be dropped in later without damaging the surrounding surface. This is typically sold as a box of six, matching multi-speaker install projects. Using the correct AC-MR4 ring ensures a tidy, professional finish and a secure fit for the AC-C4T.
