Sonance Thinline Solid Surface BPC – Flush Subwoofer Bracket

Product Overview

The Sonance Thinline Solid Surface BPC is the mounting bracket used to install the BPS6 Thinline bandpass subwoofer flush into solid surface materials such as stone, engineered quartz, or millwork panels. It is designed for integrators finishing a totally flush, trimless subwoofer installation where standard drywall mounting hardware will not suit the wall or ceiling material. The bracket supports 3-inch, 4-inch, or 6-inch trim port options to match the finished opening.

Product Description

Solid surface materials such as stone and engineered quartz require different mounting hardware than standard drywall, since the panel thickness and rigidity are not the same as a typical wall assembly. The Thinline Solid Surface BPC is built specifically for this application, giving the BPS6 Thinline bandpass subwoofer a secure, low-profile mounting point in solid surface walls or ceilings while preserving the totally flush, trimless look that defines the Sonance Thinline platform. The bracket supports three port trim sizes, 3-inch, 4-inch, or 6-inch, so the finished opening can be matched to the room and the subwoofer output required. As with the drywall version of this platform, the woofer and tweeter in the BPS6 module pivot independently once installed, allowing sound to be aimed at the listening area even though the subwoofer itself sits flat against the surface. Integrators building a discreet flush subwoofer installation into a stone feature wall, kitchen island, or custom millwork panel typically specify this solid surface bracket rather than the standard gypsum mounting platform. Because solid surface fabrication is usually done off-site, the cutout dimensions and port size should be confirmed with the fabricator before the material is cut.
