Sonance 5/8" Square Medium Mounting Platform – AS68RS Bracket

Product Overview

The Sonance 5/8" Gypsum Mounting Platform (AS Medium Square) is the drywall bracket used to install the AS68RS Architectural Series speaker or BPS8 bandpass subwoofer flush into a 5/8" wall or ceiling. It is built for integrators handling medium-format, totally-flush installations where the finished opening reads as a clean 8-inch grille rather than a visible speaker frame.

Product Description

A flush-mount, trimless speaker or subwoofer only looks correct when the mounting platform behind the grille is level and properly seated in the wall or ceiling material, and that is the job of this gypsum mounting platform. It is engineered for 5/8" standard drywall and configured for a square 8-inch grille opening, matching the AS68RS speaker or BPS8 bandpass subwoofer in the medium Architectural Series lineup. The patented platform design lets an installer fine-tune grille leveling during finish-out, which is what gives Sonance flush speakers their totally flush, trimless appearance rather than a proud or recessed frame. Because the woofer and tweeter in the companion speaker pivot independently, sound can still be aimed at the listening area even though the mounting platform sits flat against the surface. Integrators speccing in-ceiling speakers for a flush-finish room typically select this platform together with the matching AS68RS speaker or BPS8 subwoofer and grille, since the components are sold separately and must be matched by shape and drywall thickness. The mounting platform carries a longer warranty term than the visible grille, since it becomes permanent, inaccessible infrastructure once the wall is finished.
