Abstract:
A blended acoustic folded horn and reflector provides for throughput of higher frequency bands without giving rise to standing waves. The horn includes a parabolic region intersected by a first direct radiant axis centered on the throat. The parabolic region is shaped and oriented to define a reflected radiant axis through the mouth for frequency components of the acoustic input above a cut-off frequency. The parabolic region operates to focus sound in the upper portion of the operational frequency range of the loudspeaker and to reflect the resulting focused sound beam along a second radiant axis through the mouth of the folded horn.
