Sonance IS4SpeakerInstallation

Sonance IS4 Speaker Installation Shim Set — shims that adjust the mounting depth of Sonance IS4 Series in-ceiling or in-wall speakers for precise flush-fit installation in varying wall or ceiling thicknesses.

The IS4 Shim Set provides 1/2-inch and 5/8-inch depth shims to accommodate different drywall thicknesses, ensuring the speaker sits flush with the ceiling or wall surface regardless of substrate depth. Correct depth alignment prevents the driver from sitting proud of or recessed into the surface, which would affect both aesthetics and acoustic performance. The shims also reduce vibration transmission between the speaker frame and the surface material. Intended for use with Sonance IS4 Series in-ceiling and in-wall speakers by professional custom installers.
