Abstract
A speaker device includes a bass driver mounted in the internal space of an enclosure for generating a bass output. The bass driver has a central axis along which a piston area of the bass driver actuates oriented at an oblique angle relative to the bottom end of the enclosure to increase bass driver size and acoustic output and to reduce acoustic frequency distortion by providing a varying distance between the bass driver and the top and bottom ends of the enclosure. An elastomeric reflector-damper plate is spaced apart from the bass driver in the internal space in the enclosure. The reflector-damper plate radially disperses low to midrange audio frequencies of the bass output of the bass driver around the enclosure to further reduce acoustic frequency distortion. Electronic subsystems in the internal space coupled to the bass driver receive and process input audio signals to be rendered by the bass driver.
