Disadvantage: Less efficient as compared to ported design. Overall The box internal volume should be as close as possible to the recommended by the manufacturer. If a box is smaller than what it is supposed to be, the sound will be tighter, but more amplifier power will be required. If the box is too big, then the sound will be muddy. |

Disadvantage: Larger enclosure size, Calculating enclosure and port dimensions more difficult,easy to blow woofer if power handling limit is exceeded. Overall The box itself acts as an amplifier, yielding to more bass than a sealed enclosure (3 to 4 dB). Ported boxes do not have a linear frequency response. If the box is not built according to specifications, it will not sound good. The box design acts as a filter, cutting off lower frequencies. |

This is a very important step to ensure you have the appropriate volume needed to provide proper performance of the subwoofer. For example, if you wish to build an enclosure for a 15" and you only have one cubic foot space available, it would be better to use a 10" because the volume is not large enough to allow the 15" to perform properly. The small enclosure would restrict the performance of the 15" not allowing it properly reproduce low frequencies. |
