Abstract
A coaxial loudspeaker has a first driver producing sound within a first frequency band and a second driver coaxial with the first driver producing sound within a second higher frequency band. The first driver includes a first moveable membrane coupled and moveable relative to a frame to generate sound waves within the first frequency band. The first moveable membrane extends from adjacent a central axis to an outer part above and spaced apart from a rim of the frame, the outer part being resiliently coupled to the rim. The second driver includes a second moveable membrane generating sound waves within the second frequency band. The second moveable membrane is behind or below the first moveable membrane and the resilient coupling is behind the first moveable membrane extending from the rim to the outer part so the surround is not an obstacle to second driver sound waves.
