In-Ceiling Subwoofer and Mounting Kit

The Presence 10" In-Ceiling Subwoofer with Mounting Bracket is designed to mount directly to 16" O.C. and 24" O.C. wooden frame construction members (ceiling joists and trusses). This complete subwoofer kit has everything you need to install the Presence Subwoofer into your ceiling.

  • Designed for new construction and select retrofit applications
  • Power handling at 125 watts nominal (250 watts max.)
  • Mounts directly to wooden frame construction members
  • Frame and grilles can be painted to match your ceiling
  • Unique cone design and infinite baffle
  • Kapton voice coil former

Designed to match other OEM speaker models, the subwoofer with its grille in place looks identical to the Presence 8" 15-Degree Angled LCRS Speaker (A-8LCRS, sold separately).

Installation Details

The integrated system weighs approximately 11 pounds altogether, which is much too heavy to be suspended overhead in sheetrock, especially due to the powerful and potentially damaging excursions from the unit's 10" long-throw woofer. For the sake of safety, the system is designed so the entire assembly is mounted directly to the structure's framing members. It actually reinforces the sheetrock by unitizing the assembly and the structure's framing together.

While the subwoofer is primarily intended for new construction installs, it may also be retrofitted into existing construction after the sheetrock is in place, as long as the opposite side is accessible to the installer. The structural mounting bracket may be installed from above the sheetrock.
