In-Ceiling Subwoofer System
Installation Guide
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 to16" OC, 19.2" OC & 24" OC wooden frame construction
members (ceiling joists and trusses).
The integrated system weighs approximately 11 pounds, which is much too
heavy to be suspended overhead in sheetrock especially when you take
into consideration thepunishing excursions the 10" long-throw woofer is
capable of.
For the sake of safety, the system is designedsuch that the entire assembly
is mounted directly to the structure’s framing members. It actually re-
enforces 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. Thismay 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 consistsof 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 pair22.5” long to span 24” OC
members. These fasten to the framing members with screws (Item 2) as
shown in Figure 2. The appropriately sizedset of rails for 19.2 OC framing
is availableseparately (MBR-192).
Mount the white plastic bracket to the appropriate set of rails with the
shorter screws (Item 1in Figure 1). Place the white plastic bracket in the
middle position and tighten the screws.
Put the assemblyin 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 withthe rafters.
Now that the steelmounting 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.
