A ported box gets louder because it uses a column of air to act almost as another driver. It just simply uses the reverse energy of the cone to create useful acoustic gain. Think about it like this, in a sealed box a driver has a roll off point that is determined by the size of the box and the driver. There is not much that a designer can do to control the roll off frequency. However, in a ported box the designer as a lot more control on where and how much response will roll off. Using this control a designer could actually build a flatter response box with a ported design...</p></blockquote><p></p>
