The MB-C10 combination mounting & pre-construction bracket and the C-10SW 10" woofer
assembly are packaged and sold separately. These instructions accompany both.

The MB-C10 & C-10SW In-Ceiling Subwoofer system has been designed to
mount directly to 16" OC, 19.2" OC & 24" OC wooden frame construction
members (ceiling joists and trusses).

The integrated system weighs approximately 11 pounds, which is muc h too
heavy to be suspended overhead in sheetrock especially when you take
into consideration the punishing excursions the 10" long-throw woofer is
capable of.

For the sake of safety, the system is designed such that the entire assembly
is mounted directly to the structure’s framing members. It actually re­enforces the sheetrock by unitizing it, the assembly and the structure’s
framing together.

Primarily designed for “new construction”, in some cases it may also be
retro-fitted into existing construction, which is to say, after the sheetrock is
in place. This may be accomplished when access to the “other side” may
be gained. The structural mounting bracket may be installed from above
the sheetrock.

INSTALLATION OF MB-C10

The MB-C10 consists of five separate pieces and two different types of
screws. There are two pairs of steel mounting rails supplied. One pair

14.5” long to span 16” OC members and one pair 22.5” long to span 24” OC
members. These fasten to the framing members with screws (Item 2) as
shown in Figure 2. The appropriately sized set of rails for 19.2 OC framing
is available separately (MBR-192).

Mount the white plastic bracket to the appropriate set of rails with the
shorter screws (Item 1 in Figure 1). Place the white plastic bracket in the
middle position and tighten the screws.

INSTALLATION OF C-10SW

Remove the grille with the included Grille
Removal Tool. Cut the white film out of
the mounting bracket with a utility knife.

Connect the speaker wires and place the
C-10SW up into the ceiling by holding the
black steel installation handle. Use the
guides shown below in Figure 3 to align
the speaker frame with the mounting
bracket.

Attach the speaker to the mounting
bracket with the four black screws that are
included with the C-10SW.

Remove the installation handle by
loosening the two screws that hold it in
place and turning it so that the screw
heads pass through the keyhole openings.

Tighten the two screws that held the
handle in place.

Attach the grille with spun cellulose insert.
The white insert goes between the driver
and the grille to improve the appearance.

CAUTION: THIS
INSTALLATION HANDLE
MUST BE REMOVED
BEFORE THE SUB IS
ACTIVATED

Put the assembly in position between the rafters
and fasten with the longer screws (Item 2 in
Figure 1). Make sure that the room-side of the
rails are flush with the rafters.

Now that the steel mounting rails are fastened to
the rafters and spaced properly, the position of
the mounting bracket along the rails can be
adjusted. When used with 24” OC framing members there is considerable
space to slide the round plastic mounting frame back & forth on the rails to
the desired location; installations into 16” OC provide little space for
adjustment.

Leave the white film that covers the mounting opening in place until you are
ready to install the C-10SW.
