Abstract
A loudspeaker system includes a speaker enclosure having an opening in a front wall, and a speaker manifold mounted within the speaker enclosure and communicating with the opening. The speaker manifold includes a pair of substantially parallel side walls, a back wall, and top and bottom walls, defining a manifold chamber. The wall opposite the back wall is substantially open to define a manifold opening and to permit the communicating. The manifold opening is substantially in alignment with the front wall opening. A woofer is mounted on a first wall of the speaker manifold. An acoustic vent is mounted on a second wall of the manifold, such that the woofer and the acoustic vent face each other at one of about a 180 degree angle or about a 90 degree angle.
