The Sonance DISC System is a depth-sensing measurement tool for Invisible Series speakers, allowing the installer to verify finish thickness over the speaker before the wall or ceiling is signed off. The system uses a high-accuracy depth gauge paired with embedded locator discs to measure the thickness of plaster, paint, or wallpaper applied over the surface of a Sonance Invisible Speaker.

Verified finish depth keeps acoustic performance within manufacturer specification and ensures a consistent listening experience across multiple Invisible Series installations on the same project. The DISC gauge is the recommended commissioning tool whenever Sonance Invisible Series speakers are deployed in luxury hospitality, retail, museums, galleries, and high-end residential architecture.

Use the DISC gauge at the same stage as paint/plaster sign-off so the finish trades can correct any out-of-spec coverage before the wall is committed. One gauge supports an entire project's Invisible Series commissioning across multiple cabinets.
