A loudspeaker enclosure with a cylindrical compression chamber to which an electro-dynamic loudspeaker is mounted at the front. The rear of the cylindrical compression chamber is faired to the front of a tapered triangular pipe with a slot to connect the air column in the cylinder to the air column in the triangular tapered pipe. A baffle inside the tapered triangular pipe splits the tapered pipe into two triangular pipes, effectively increasing the length of the triangular air column substantially. This tapered triangular air column expands into an extended triangular bell and then the room.
