You’ve got your subwoofer, now what about the box?
There are three different types of subwoofer boxes that you should be looking to consider, depending on what type of subwoofer you get.
The sealed subwoofer enclosure is described by great transient response, excellent low frequency power handling, and a smaller box size. When a speaker is attached in a box, the air in the box turns to shape a spiral. Yet, sealed systems incline to hurt from complex limit points and lower sensitivity than the other low rate systems. They are usually the subwoofer of choice due to their great response.
A ported enclosure system contains of a driver fixed on a side of a box that has an open area that lets the air in and out of the box. The port is there to tune the closed off space so that the rear wave of the speaker boosts the front wave of the speaker. This tends to results in a subwoofer with higher effectiveness. At lower frequencies, the opening adds greatly to the output of the system. The box design itself is made to perform as a filter to cutting off lower frequencies.
Bandpass boxes will produce more bass than either of the previous boxes mentioned, but over a thinner range of frequency. Working as a filter, the box blocks lower and higher frequencies, and in most cases a crossover is not needed. These boxes are typically big and provide very accurate volumes. Bandpass boxes also usually cover distortion which at times leads to damaged subs. Bandpass enclosures are very efficient in the band of frequencies that they are tuned to or pass.
