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.

Claims (16)

1. A loudspeaker system, comprising:

a speaker enclosure having a first opening and a second opening;

a first speaker manifold shaped substantially as a first rectangular box to define a first manifold chamber, the first manifold chamber mounted within said enclosure and communicating with the first opening,

wherein the first rectangular box includes a first back wall, four first side walls, and an open first front side, and

wherein the first front side is substantially in alignment with the first opening;

a second speaker manifold shaped substantially as a second rectangular box to define a second manifold chamber, the second manifold chamber mounted within said enclosure and communicating with the second opening,

wherein the second rectangular box includes a second back wall, four second side walls, and an open second front side, and

wherein the second front side is substantially in alignment with the second opening;

a woofer mounted on a one of the first side walls; and

a passive radiator mounted on one of the second side walls.

2. The loudspeaker system of claim 1 , wherein the woofer and the passive radiator woofer face away from each other.

3. The loudspeaker system of claim 1 , wherein the side wall in which the passive radiator is mounted is substantially parallel to the side wall in which the woofer is mounted.

4. The loudspeaker system of claim 1 , wherein a surround of the woofer is partially covered by the speaker enclosure.

5. The loudspeaker system as recited in claim 1 , wherein the speaker enclosure further includes a power amplifier.

6. The loudspeaker system as recited in claim 1 , wherein the first opening and the second opening are on a same side of the speaker enclosure.
