Sonance 5/8in Solid Surface Medium Platform – AS68RS Bracket

Product Overview

The Sonance 5/8-Inch Solid Surface Mounting Platform (AS Medium RS) is the bracket used to flush-mount the AS68RS Architectural Series speaker or BPS8 bandpass subwoofer into solid surface materials such as stone, engineered quartz, or millwork panels. A single platform serves both round and square grille configurations, simplifying inventory for solid-surface projects. It is intended for installations where standard drywall mounting hardware is not suitable for the wall material.

Product Description

Solid surface materials behave differently from drywall during installation, requiring a mounting platform engineered for the added rigidity and thickness of stone, quartz, or millwork panels. This 5/8-inch solid surface platform is built specifically for that application, supporting the AS68RS speaker or BPS8 bandpass subwoofer in the medium Architectural Series lineup, and unlike the drywall version, one platform accommodates either a round or a square grille rather than requiring separate parts. That flexibility is useful on custom millwork or stone feature walls where the exact trim shape may not be finalized until fabrication. As with other Sonance flush mounting platforms, the design allows precision grille leveling so the finished opening sits totally flush against the solid surface material. Integrators working on flush speaker installations in kitchens, bars, or feature walls with stone or quartz surfaces typically specify this platform rather than the standard drywall version. Because solid surface fabrication is done off-site in many cases, the cutout dimensions and platform depth should be confirmed with the fabricator before the material is cut.

Key Features

• Solid Surface Engineered — Built for stone, engineered quartz, and millwork panel installations rather than standard drywall.
• Single Platform, Round or Square — One bracket serves both grille shapes, reducing inventory for solid-surface projects.
• Matches Medium Architectural Series — Pairs with the AS68RS speaker or BPS8 bandpass subwoofer platform.
• Precision Grille Leveling — Supports a totally flush, trimless finish once the grille is installed.

Typical Applications

• Kitchen islands, bars, and feature walls finished in stone or engineered quartz
• Custom millwork installations requiring a flush speaker or subwoofer
• Projects where round-versus-square trim is finalized during fabrication

Frequently Asked Questions

Does one platform really work for both round and square grilles?

Yes. This solid surface platform is designed to accept either a round or square grille, unlike the drywall version which requires a shape-specific platform.

Is this platform used with drywall installations?

No. It is engineered specifically for solid surface materials such as stone, quartz, or millwork; a separate gypsum platform is used for standard drywall.

Does this include the AS68RS speaker or grille?

No. The mounting platform is sold separately from the speaker, subwoofer, and grille.

Who should confirm the cutout dimensions before fabrication?

Coordinate cutout dimensions with the solid surface fabricator before the material is cut, since fabrication is typically done off-site.

What warranty applies to this mounting platform?

Sonance mounting platforms in this family are covered by a 15-year limited warranty.
