SONANCE MERLOT® MR/SSMR

Insulating the Ceiling Cavity

You can also reduce sound transmission to adjacent rooms and improve speaker performance by inserting a sheet of unfaced fiberglass insulation over the back of the speaker. To reduce mechanical noise produced by unsupported drywall, install fiberglass insulation in the ceiling bays adjacent to the speaker location.

Sonafill®

Sonafill (part #91928) is a retrofittable acoustical treatment system consisting of two pillows and four tiles that virtually eliminates noises produced by resonating drywall. The tiles have pressure-sensi- tive adhesive and are installed on the back of the

drywall on either side of the speaker between the ceiling joists; the pillows are then stuffed in place behind the tiles. The system dramatically improves midbass sound quality and reduces sound transmission into adjacent rooms.

Installing the Speakers

Before Installation: New Construction

For installations in new construction, Sonance recommends using a Merlot MR FlexBracket (part #91973) to reserve a location for the speaker. The FlexBracket has perforated wings that can be positioned anywhere around the bracket, and is nailed or screwed to the ceiling joists. This serves as a guide for the drywaller so that the speaker hole will be in the desired location once the drywall is installed.

Before Installation: Retrofit

1.Determine the location for the speaker (see Speaker Placement on page 4).

2.Perform an obstruction survey to be certain that there are no joists, conduit, pipes, heating ducts, or air returns in the ceiling cavity that will interfere with the speaker.

3.The cutout for all Merlot MR and SSMR speakers is 5 7/8” (149mm) in diameter. There also must be at least 3½” (89mm) depth within the ceiling cavity for the speaker.

4.Position the included cutout template where the speaker is to be located and pencil an outline on the ceiling.

If you are unsure about obstructions, drill a small hole in the center of the outline and insert a coat hanger wire into the hole to feel-around for possible obstructions.

5.Cut the mounting hole using a keyhole or drywall saw, and run the speaker wires from the mounting hole to the amplifier location.

Consult local building codes before running speaker wires through ceilings.
