A loudspeaker horn may comprise at least two horn sections, each extending from an inlet to a mouth. A first plurality of outlet channels is disposed in an interleaved column with a second plurality of outlet channels. A loudspeaker cabinet may comprise a primary enclosure having a front wall, the front wall having an aperture in which a low frequency loudspeaker driver is mounted. The loudspeaker cabinet further comprises a top baffle section having a top end and a bottom baffle section having a bottom end, each extending vertically from the primary enclosure. The top baffle section has a first width that gradually increases towards the top end and the bottom section has a second width that gradually increases towards the bottom end.
