3.  Connect Speaker Wires

•  Insert the speaker wires into the binding posts on the speaker noting proper polarity. 

4.  Speaker Mounting

•  Attach the speaker panel screw flanges directly to the structural framing using the provided wallboard screws (See 

Figure 6). The panels have been pre-drilled with the proper number of holes. Be sure that all of the screws are 

installed and that they hold securely to the framing.

•  Add screws to the wallboard surrounding the speaker as well.
•  Do not use nails.

TIP: Make sure the tip of the screw is on the side of the screw hole toward the outside edge. This creates an outward 

pull or stretching effect on the speaker. 

5.  Recheck Speaker Registration

•  Once the speaker is secured, recheck that the outer flange of the speaker is flush with the surrounding wallboard. 
•  Place a 4-foot straight edge across middle of the speaker to verify that the speaker face protrudes approximately 

1/16" (2mm) beyond the wallboard in each direction. 

•  Check that the speaker is not warped from strain caused by uneven framing. A warped speaker frame will cause the 

speaker face to bulge. 

•  Having the correct registration minimizes the amount of joint compound that might be built up over the face of the 

speaker during the finishing process. This 1/16" (2mm) protrusion of the speaker face will become invisible after the 

seams are properly finished and joint compound is feathered out from the front of the speaker appropriately. 

TIP: If you tried to tighten the screws but unable to achieve a satisfactory result, try placing approximately 4" (102 mm) 

of thin shim material under the mounting flange at the center point. 

6.  Test Speaker Sound

•  Before proceeding with any wall finishing, test each speaker with an amplified sound source. 
•  Test with music at listening volume in addition to test tones to ensure full functionality. Make note of sound coming 

from high, mid, and low frequency drivers of each speaker. Check for any rattling or vibration. 

•  Now is the time to correct any potential issues.

7.  Seam Finishing

•  After the registration and sound check, seam finishing can proceed. The speaker panel should be finished in-place, 

similar to any other piece of wallboard. 

•  Self-adhesive nylon mesh tape is recommended due to its ease of use, however paper tape is also acceptable (See 

Figure 7).

•  Use only air-dry joint compounds and plasters for seam finishing. Do not use chemically curing joint compound.
•  For best results, we recommend at least three light applications of joint compound, sanding between coats. 
•  Allow 24 hours between each application of joint compound for complete drying. Failure to allow the joint compound 

to completely dry between applications may result in fine hairline cracking around the speaker. 

•  The joint compound should be spread beginning 2”-3” in from the speaker edge and then feathering outward 16”-

20” in order to achieve a smooth, flat transition. 

•  It is important that enough joint compound be applied around the speaker to make a very gradual transition from the 

surface of the wallboard to the face of the speaker panel. Every situation is different, but it will normally take at least 

a 16”-20” (30cm) fan of joint compound around the perimeter of the panel to create a flat-looking transition. 

•  Be sure to feather the joint compound away from the speaker as to not build up more than the maximum allowed 

1/16" (2 mm) of joint compound over the face of the speaker panel (See Figure 8).

•  Conceal series speakers do not require a skim coat to attain a smooth finish. However, some advanced finishing 

techniques and materials such as Venetian plaster or heavy plaster coats may require skimming over the front of 

the speaker. In these situations, it may be necessary to shim the speaker proud of the surrounding wallboard so 

that we avoid build-up of more than 1/16" (2 mm) in thickness on the face of the speaker.
