Sage Series in-wall speakers (with its integral aluminum back boxes) are mounted via screws into the aircraft-grade aluminum extrusion SE enclosure. The unique flexible rubber-magnetic mounting system then allows for a thin, stainless steel grill to conform to variations in wall surfaces. An included tool is used to obtain a uniform grill distance from the wall’s surface – the grill sort of floats above the wall surface, eliminating the need for a bezel.
