Abstract
A modular horn type loudspeaker and a modular horn array formed of modular loudspeakers. An acoustic horn includes a first acoustic module. The first acoustic module includes a first acoustic driver and a first acoustic duct, for conducting acoustic energy from the first acoustic driver. The first acoustic duct has a first opening through which acoustic energy is radiated. The first acoustic duct is characterized by a first centerline. A second acoustic module includes a second acoustic driver and a second acoustic duct, for conducting acoustic energy from the acoustic driver. The second acoustic duct has a second opening through which acoustic energy is radiated. The second acoustic duct is characterized by a second centerline. The first module and the second module are 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.
