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 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 much 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 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.  This may be accomplished when access to the “other side” may 

be gained.  The structural mounting bracket may be installed from above 

the sheetrock.
