Sealed subwoofer boxes tend to be much smaller than ported enclosures, offered that they use the air inside the box as a"spring"for the enclosure. However if the box gets too large, the"spring"effect that the air creates might be lost, losing loudness and crispness. Sealed enclosures develop tight, right bass and have a flat frequency response curve. They are the enclosure of choice when quality may possibly be the ultimate goal from the system set up. Generally, the larger the box, the lower the tone of the bass achieved. Not only is there a size difference, but there is also a difference in sound compared to a ported box. If you do not have much space, it may be a good concept to go with a sealed box.
