Abstract
A speaker assembly for being mounted within a wall is provided. The speaker assembly has a housing and a plurality of transducers supported by the housing. Each transducer has a front radiation surface and a radiation rear surface adapted to radiate sound along a central axis. The transducers are arranged relative to each other so the central axes of acoustic radiation of each of the transducers intersect at a circumcenter defined between the plurality of transducers to substantially cancel vibrations from the plurality of transducers. A slot is formed adjacent of each of the transducers. The slot extending a depth dimension of the assembly between a slot opening for transmitting acoustic radiation from the plurality of transducers and a back wall of the housing, wherein the depth dimension is generally perpendicular to the central axes of acoustic radiation of each of the transducers.
