6. The loudspeaker assembly of claim 1 , wherein the acoustic horn includes a forward end adjacent the front side of the enclosure and a back end adjacent the first transducer, and wherein the rearward projection projects from a portion of the acoustic horn between the forward end and the back end.

7. The loudspeaker assembly of claim 1 , wherein the depending extension wall is integral with the acoustic horn.

8. The loudspeaker assembly of claim 1 , wherein the rearward port portion and the rearward projection both extend in a direction that is parallel to the forward direction.

9. A loudspeaker assembly comprising:

an enclosure having an open front side defining a forward direction for projecting sound;

a first transducer positioned within the enclosure;

an acoustic horn coupled with the first transducer, the acoustic horn having a flared front surface configured to direct the sound from the first transducer, and the acoustic horn having a rear surface facing an interior of the enclosure;

a second transducer positioned within the enclosure, wherein the second transducer is a woofer assembly configured to output sound in a lower frequency register than the first transducer;

a mounting baffle secured to the interior of the enclosure for supporting the second transducer; and

a port establishing fluid communication between the interior of the enclosure and an outside environment in front of the open front side of the enclosure, wherein the mounting baffle and the acoustic horn cooperate to form the port,

wherein, at a forward end of the acoustic horn, an extension wall depends therefrom to turn the port in a direction transverse to the forward direction, the depending extension wall lying directly in front of a peripheral portion of a cone of the woofer assembly,

wherein the acoustic horn has four flared sides, one of which is positioned adjacent the second transducer and extends to the depending extension wall as an integral extension thereof, and

wherein a front surface of the extension wall depending from the acoustic horn supports an exterior grille against deflection into the interior of the enclosure.

10. The loudspeaker assembly of claim 9 , wherein a first port portion of the port is formed by a forward face of the mounting baffle and the extension wall, wherein a second port portion of the port is formed by a rearward port portion formed by a rearward extending flange of the mounting baffle and a rearward projection extending from the rear surface of the acoustic horn, and wherein the port includes an elbow formed at a junction of the first and second port portions, the elbow having an inner radius formed by the mounting baffle and an outer radius formed by the rear surface of the acoustic horn.

11. The loudspeaker assembly of claim 10 , wherein the rearward extending flange and the rearward projection both extend in a direction that is parallel to the forward direction.

12. The loudspeaker assembly of claim 10 , wherein the depending extension wall is integral with the acoustic horn.

13. The loudspeaker assembly of claim 9 , wherein each of the depending extension wall, the rearward extending flange, and the rearward projection includes a substantially planar surface that defines the port.

14. The loudspeaker assembly of claim 9 , wherein the depending extension wall is substantially planar.

15. The loudspeaker assembly of claim 9 , wherein the acoustic horn includes a forward end adjacent the depending extension wall and a back end adjacent the first transducer, wherein a rearward projection projects from a portion of the one of the flared sides between the forward end and the back end, and wherein the rearward projection extends a length of the port.

16. A loudspeaker assembly comprising:

an enclosure having an open front side defining a forward direction for projecting sound;

a first transducer positioned within the enclosure;

an acoustic horn coupled with the first transducer, the acoustic horn having a front surface configured to direct the sound from the first transducer, and the acoustic horn having a rear surface facing an interior of the enclosure;

a second transducer positioned within the enclosure;

a mounting baffle secured to the interior of the enclosure for supporting the second transducer;

a port establishing fluid communication between the interior of the enclosure and an outside environment in front of the open front side of the enclosure; and

a grille at least partially closing the open front side of the enclosure,

wherein the acoustic horn has four sides, one of which is positioned adjacent the second transducer and includes an integral forward extension and an integral rearward extension between which a flared portion of the acoustic horn rear surface cooperates to form the port with the mounting baffle,

wherein the forward extension has a wall thickness greater than a wall thickness of the rearward extension and greater than a wall thickness of the flared portion of the acoustic horn, and

wherein the forward extension of the acoustic horn supports the grille against deflection into the interior of the enclosure.
