MOS36K Mounting Steps

1. Mount temporary holders to ceiling joists.

Cut a couple of 2” x 4”s or 1” x 4”s, a few inches wider than the ceiling joists. Then with a couple of drywall screws, mount the temporary holders to the joists. (Drywall screws not included).

These temporary holders will help you hold up the MOS36K and make the speaker mount flush to the future drywall. Using a level, check that your temporary holders are evenly level, adjusting as needed.

2. Adjust the rails, as neccessary, to fit ceiling joists.

Place MOS36BOX in desired final location.

 *Ensure the rail ends are turned outwards.*

Then, using a Phillips screwdriver, loosen the screws on each side of the system rails, and extend them so they reach the ceiling joists. Afterwards, make sure to re-tighten screws once the rail length matches the ceiling joists.

NOTE: The cabinet also has screw openings on the short sides so you can move the rails from the long side to the short sides for tight space installations.

3. Securely fix the rail brackets to the joists.

Use a drill and the included screws. Ensure each the screws on each side of the rails are evenly inserted, for a level positioning.

4. Remove the temporary wood supports from the joists.

5. Ensure the face of the speaker is plumb with the joists.

6. Speake wire connection:

To connect the speaker wire to the 2-Pin Phoenix Connector on the Subwoofer module, strip approximately 3/16” (5mm) of the insulation off each wire, and to avoid stray strands, twist them at the end.

Insert each wire into the square opening with the correct polarity, on the phoenix connector. Use a small flathead screwdriver to tighten the corresponding screw to secure the wire. Lastly, using the screwdriver, tighten the 2-Pin Connector Housing to the MOS36K Subwoofer Enclosure.

7. Ceiling Cut Out Steps

Use the cut-out template to mark the cut-out for the speaker (MOS36MRM) on the drywall/ surface material.

Trace along the inside of the Cut-Out Template, then use a keyhole or drywall saw to cut out the hole.

8. Installing Flanged or Flush Trims:

The Flanged and Flush trims can be added to the cutout, without drywalling over. If the Port Tube cover does not reach the edge of the drywall, or if using sheetrock that is thicker than ½’’, attach the appropriate number of spacers, according to the depth of the drywall ceiling, for the trim to fit.

NOTE: If using a square trim, place the MRM Adapter Ring (Piece: C1) inside, with the Screw Holes facing towards the Port-Tube, and screw into the remaining Spacers and Subwoofer Enclosure as normal.

•  Installing Flanged Trim

Then, install the desired rim ring over the spacers and secure the trim ring into all spacers & subwoofer enclosure, using the 3 included Trim Ring Screws.

•  Installing Flush Trim

Then, install the desired trim ring over the spacers and secure the trim ring into all spacers & subwoofer enclosure, using the 3 included Trim Ring Screws.

•  Installing Invisible Trims

Then, install the desired trim ring over the spacers and secure the trim ring into all spacers & subwoofer enclosure, using the 3 included Trim Ring Screws.

Testing the Speaker

The MOS36MRM (Mid-Range Module) should be inserted into the MOS36BOX Subwoofer assembly to test the unit, before plaster work is performed. Securely fix the 2-Pin Connectors together, from the MOS36BOX to the MOS36MRM piece, for a sound test.

To disconnect/release, press down on plastic latch.

Applying Drywall / Surface Material

Next, before installing the drywall over the Invisible Trim, place the correct Placeholder Sponge inside, to protect the cut-out hole & port tube from any debris during the drywalling process.

Apply the drywall/ surface material, plaster & paint, over the invisible trim, using mesh tape to cover any installation seams. Apply joint compound and level out compound to conceal seams. Make sure to mud up to the rim of the trim ring spacer. Then remove the Placeholder Sponge.

Securing the Mid-range Module (Speaker)

The MOS36MRM (Mid-Range Module) can now be inserted into the MOS36BOX Subwoofer assembly:

With Flanged Round Trim

With Flanged Square Trim

Rotate the MRM Module by hand, CLOCKWISE, until the three (3) metal wings rest inside the three (3) tabs of the Trim.

Finally, secure the MRM Module within the Subwoofer assembly using the provided Socket Head Screw and Hex Key.

Adding the Grille

To complete the installation, use the pieces of included adhesive tack, to secure the press grille in place. The grille can be spray painted to better match the ceiling color and environment, prior to being attached.

Troubleshooting

If you have a problem, try isolating it first. For example, if you’re playing a DVD and there is no sound, try replacing the DVD with an MP3 player to see if you get sound. If it does work, then the problem is with the television, DVD player, or the cables connecting them. If it doesn’t work, the problem will be with the amplifier, speakers, or those cables.
