The mineral fiberboard front can be cut to suit the speaker that will go in later, so one housing covers several models. After the pour, the speaker installs into the housing with a clean, flush finish and no core drilling. The halogen-free, temperature-resistant box and grounded steel cover make it suitable for public buildings. Compatible speakers include CELO2, CELO5, CELO6, CENA5, CENA7, CIRA5, CIRA7 and CIRA8. Planning concrete-ceiling audio requires coordination with the general contractor before the pour; Creation Networks handles that as part of system design.\u003c\/p\u003e\u003ch2\u003eWhat are the key features of the AUDAC CMM306 concrete speaker box?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCast-in-place housing\u003c\/strong\u003e — set in the formwork so speakers install after the pour.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom cut-out front\u003c\/strong\u003e — the mineral fiberboard front is cut to fit the chosen speaker.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecast ready\u003c\/strong\u003e — suits integration at precast concrete factories.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHalogen-free box\u003c\/strong\u003e — temperature-resistant synthetic material.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounded steel cover\u003c\/strong\u003e — galvanized metal plate for safety.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUp to 110 mm depth\u003c\/strong\u003e — fits a wide range of AUDAC flush-mount speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e — backed by a 5-year AUDAC manufacturer warranty.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWhere is the AUDAC CMM306 concrete speaker box typically used?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGovernment space\u003c\/li\u003e\n\u003cli\u003eAuditorium\u003c\/li\u003e\n\u003cli\u003eCommercial meeting space\u003c\/li\u003e\n\u003cli\u003eMulti-purpose room\u003c\/li\u003e\n\u003cli\u003eHouse of worship\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cdiv style=\"overflow-x:auto;-webkit-overflow-scrolling:touch\"\u003e\u003ctable style=\"border-collapse:collapse;width:100%;min-width:300px;table-layout:fixed\"\u003e\n\u003ccolgroup\u003e\n\u003ccol style=\"width:44%\"\u003e\n\u003ccol style=\"width:56%\"\u003e\n\u003c\/colgroup\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eCMM306\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e12.05 x 4.72 in (Ø x D)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eCut-out\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e11.02 in (Ø)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eBuilt-in depth\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e4.33 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eFront material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eMineral fiberboard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eBox material\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eSynthetic, halogen-free and temperature resistant\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eCover\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eGalvanized metal plate, grounded\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eCompatible speakers\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003eCELO2, CELO5, CELO6, CENA5, CENA7, CIRA5, CIRA7, CIRA8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;vertical-align:top\"\u003e\u003cstrong\u003eWarranty\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px\"\u003e5 years\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cdetails\u003e\u003csummary\u003e\u003cstrong\u003eWhen does the CMM306 need to be installed?\u003c\/strong\u003e\u003c\/summary\u003e\u003cp\u003eBefore the concrete pour.
