Patent ID: 8422713

Claim:
A loudspeaker system, comprising: two or more fully spherical enclosures, each enclosure separately housing a pair of transducers, each pair of transducers positioned in opposition to each other and reproducing acoustic waves of a predetermined frequency range, wherein a first of said spherical enclosures comprises a woofer enclosure housing an opposed pair of low-frequency transducers operating in phase with one another, and a second of said spherical enclosures comprises an opposed pair of mid-range frequency transducers with at least one obstacle positioned between said opposed pair of mid-range frequency transducers; further wherein said mid-range frequency transducers are comprised of substantially circular diaphragms supported by structural surrounds and centrally located pole pieces, said at least one obstacle being positioned in front of said pole piece of each mid-range frequency transducer; and further wherein said at least one obstacle is substantially of a circular geometry having a circular cross section and length, said obstacle being positioned such that its cylindrical cross section is positioned proximate said pole pieces and sized to substantially reduced inharmonic nulls which would otherwise occur radial to the axis of the obstacle in its absence.
