All Concerta on-wall woofer, midrange and tweeter diaphragms are constructed of Micro Ceramic Composite (MCC), a new material created by anodizing both sides of an aluminum core. Anodizing both sides of an aluminum core adds strength and stiffness – but very little weight – to a material already well suited for use in transducer diaphragms.

With appropriate hardware, it’s possible to affix virtually any compact loudspeaker to a listening room wall, and manufacturers are free to promote any model of a certain size and weight as “wall-mountable.” But very few audio manufacturers have the facilities and expertise needed to determine just how their on-wall systems will sound when actually placed on or near a wall.
