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. The performance of Revel Concerta on-wall loudspeakers has been extensively evaluated in a variety of on- and near-wall installations through blind listening tests in the Revel Multichannel Listening Lab. Using proprietary 35-point anechoic measurements, Concerta on-wall speakers have been shown to deliver remarkably flat frequency response across an exceptionally wide listening area for clean, accurate sound in real-world listening rooms.
