Patent ID: 7624839

Claim:
A speaker system comprising: an enclosure defining an interior space; an internal baffle arrangement disposed in the interior space to divide the interior space into a front common-chamber and a rear chamber; first and second active transducers mounted to the internal baffle arrangement in an orientation to radiate sound energy into the front common-chamber and rear chamber, the first and second active transducers providing for generating sound energy predominantly in a low frequency range; and a planar based acoustic radiator mounted to the enclosure adjacent the front chamber, the planar based acoustic radiator being disposed at an oblique angle relative to the first and second active transducers and coupling low frequency sound from the first and second active transducers to outside the enclosure, the planar based acoustic radiator further incorporating a transducer providing for generating sound energy in a frequency range above the low frequency range of the first and second active transducers.
