Abstract:
1. Apparatus, comprising: a first acoustic horn, comprising a first acoustic module comprising a first acoustic driver; and a first acoustic duct, for conducting acoustic energy from the first acoustic driver, the first acoustic duct having a first opening through which acoustic energy is radiated, the first acoustic duct characterized by a first centerline; and a second acoustic module comprising a second acoustic driver; and a second acoustic duct, for conducting acoustic energy from the acoustic driver, the second acoustic duct having a second opening through which acoustic energy is radiated, the second acoustic duct characterized by a second centerline; the first module and the second module configured to be positioned and held in place so that the first and second openings are aligned to form a substantially continuous diffraction slot and so that the first and second centerlines are normal to an arc and intersect at a first one of a plurality of angles, wherein the first acoustic horn is disposed within a first enclosure and a top wall of the first acoustic horn directly corresponds to a top wall of the first enclosure and a bottom wall of the first acoustic horn directly corresponds to a bottom wall of the first enclosure.
