AUDAC CMM306 – Speaker Housing for Concrete Casting
What is the AUDAC CMM306 concrete speaker box?
The AUDAC CMM306 is a built-in speaker housing cast into concrete ceilings and walls, so flush-mount speakers can be installed after the pour. It has a mineral fiberboard front, a halogen-free synthetic box and a grounded galvanized steel cover. It accepts many AUDAC flush-mount speakers up to 110 mm built-in depth.
What does the AUDAC CMM306 concrete speaker box do?
The CMM306 is placed in the formwork before concrete is poured, either on site or at a precast plant. 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.

Frequently Asked Questions
When does the CMM306 need to be installed?
Before the concrete pour. It is placed in the formwork on site or at the precast plant.
Which speakers fit it?
AUDAC lists CELO2, CELO5, CELO6, CENA5, CENA7, CIRA5, CIRA7 and CIRA8. The fiberboard front is cut to the chosen speaker.
Can I choose the speaker later?
Yes. That is the advantage of the custom-cut front, as long as the speaker is on the compatible list and within 110 mm depth.
Is it safe for public buildings?
The box is halogen-free and temperature resistant, and the steel cover is grounded.
