The loudspeaker comprises a front loading acoustic chamber 10 which contains an acoustic loading member 4 that is supported by spacers 5 on the front baffle 9. One wall of the chamber is formed by the diaphragm of the bass loudspeaker 1. The diaphragm of the bass loudspeaker 1 is flat-faced because it has a more effective acoustic front loading surface than a conical loudspeaker diaphragm. Front baffle 9 has an exit port 6 located on the centre of the bass loudspeaker 1. The spacers 5 allow sub bass sound to pass into the exit port of the front baffle. The exit port is connected to an acoustic loading channel 7 which has a wide input area and a narrower exit vent 8 for the sub-bass sound output. The back acoustic loading for the bass loudspeaker is provided by an acoustic suspension chamber 11. |
