Sonance IS-L-PB.625 – Large Invisible Series Pre-Construction Bracket

Product Overview

The Sonance IS-L-PB.625 is a large pre-construction bracket built for Sonance Invisible Series in-ceiling and in-wall speakers. It is intended for integrators and contractors framing out speaker locations before drywall and finish work begin. The bracket lets crews lock in accurate speaker placement early, so the finish trade can proceed without guesswork later in the project.

Product Description

Invisible Series speakers from Sonance disappear into a painted or papered ceiling or wall, but that finish quality depends on getting the rough-in right the first time. The IS-L-PB.625 is sized for 0.625-inch wallboard and is used with large Invisible Series enclosures, including the IS-ENCL-L, to hold the correct opening and depth during framing. Once the wall or ceiling substrate is in place, the bracket accepts up to 3mm of topping compound, which keeps the finished surface flush and paint-ready. It supports a range of surface treatments commonly specified by architects and designers, including drywall, select plasters, wallpaper, leather, and wood veneer, giving finish carpenters flexibility on the final look. The bracket also works with Sonance's DISC (Depth Identification Sensing Calibration) System, which measures and standardizes the topping compound depth so every speaker location performs consistently once the actual driver is installed. For crews planning a large-format Invisible Series install, this bracket is typically specified alongside the IS10 speaker platform and paired in-ceiling speaker modules to keep rough-in and trim-out on the same timeline. Ordering the correct bracket size up front avoids costly rework if the wallboard thickness or compound depth is measured incorrectly in the field.
