Abstract
A loudspeaker assembly includes an enclosure defining a direction for projecting sound, a first transducer and a second transducer positioned within the enclosure, an acoustic horn coupled with the first transducer, a mounting baffle secured to the enclosure for supporting the second transducer, and a port establishing fluid communication along a port length between the interior of the enclosure and an outside environment in front of the open front side of the enclosure. The acoustic horn has a surface facing an interior of the enclosure. A forward portion of the port is formed by a forward face of the mounting baffle and an extension wall depending from the acoustic horn in a direction transverse to the direction. The port length is extended by a rearward port portion formed by a rearward extending flange of the mounting baffle and a rearward projection extending from the surface of the acoustic horn.
