Installation instructions for drywalls
The invisible cerasonar speakers allow for an easy few-steps installation into drywalls or suspended ceilings. The installation into solid masonry or a concrete ceiling requires though an additional step, namely the provision of a recess. For this purpose appropriate mounting frames are offered by cerasonar. The frames are affixed flush into the chiselled wall and accomodate for the speakers.
Before the installation is carried out in walls or ceilings, the construction should be tested for vibration noise. Light beats with the heel of your hand against the plasterboard shell reveals any weaknesses of the substructure. The cavity behind the panel must get an insulation, for example, mineral wool or according to the specifications of the architect.
The enclosed cable lugs have to be properly crimped to the connector cable. Then connect the cables following the colour coding / markings, for example, marking to plus (red). This order has to be maintained building and amplifierwise.
Insert the speaker into the prepared recess. Make sure that there is no strain between underlying insulation and panel (no compression). The speaker should be easily insertable into the opening.
Screw on the speaker according the pre-drilled holes. The heads of the drywall screws should immerse about 1 mm into the diaphragm material. Since the diaphragm has a lower density than the plasterboard panels, it’s essential to tighten the screws very cautiously.
Important: After fixing the screws a functional test using a music signal is mandatory!
As it is obligatory with single-ply plasterboard constructions, the joints between plasterboard and speaker have to be always filled with a crack bridge. The same filling material that is used against cracks in other joints can be also applied here.
The grouting / filling of butt joints and screw holes is similar to that normally used with drywalls or ceilings.
Cerasonar speaker panels are outfitted with a primer and have to be spackled all-over with the surrounding surface. Thus, Q3 and Q4 wall / ceiling qualities are easily possible.
