Loudspeaker with improved directional behavior and reduction of acoustical interference

Loudspeaker systems and assemblies are provided in which mid-frequency producing drivers are provided on opposing sides of a high frequency source comprising a linear high-frequency source connected to a waveguide. Crossover circuitry is provided such that the acoustic output from the mid-frequency...

Beschreibung
Zusammenfassung:	Loudspeaker systems and assemblies are provided in which mid-frequency producing drivers are provided on opposing sides of a high frequency source comprising a linear high-frequency source connected to a waveguide. Crossover circuitry is provided such that the acoustic output from the mid-frequency drivers overlaps with that of the high-frequency source over an intermediate frequency range associated with acoustic interference between the mid-frequency producing drivers. In some embodiments, the mid-frequency producing drivers are recessed behind the output of the waveguide, and optionally angled outwardly from the waveguide, in order decrease the distance therebetween.
