If you’ve done any woodworking you shouldn’t have much trouble when building a subwoofer enclosure. One of the main differences will probably be the material used in building subwoofer boxes as compared to other woodworking projects. When building a custom subwoofer box you will want to use minimal MDF (medium density fiberboard). TOOLS REQUIRED TO BUILD AN ENCLOSURE Safety goggles Table saw or circular saw Powered screw gun Router or jig saw Variety of sizes of drill bits Wood glue Silicone Wood screws To ensure your safety while building an enclosure, please read all manuals for the power tools you will be using, as they will include valuable information on handling the tools and safety tips. If you’re planning to build your own enclosure and are confused in what type of enclosure best suits your needs this page will help you choose what enclosure fits your needs. There are many different types of enclosures. The two most common used enclosures are sealed and vented enclosure. This page will show the advantages and disadvantages of the two enclosures. Advantages of a sealed enclosures *High power handing capability *Great transient response *Tolerant of minor enclosure size variation *Easy to construct *Smooth rolloff (12dB/octave) Disadvantages of a sealed enclosures *Requires a woofer with a long excursion for better low bass frequency response. *Can have lower sensitivity than ported enclosures. *When using high power and small enclosures, the woofer is not in an ideal cooling environment. *Less low bass as compared to a properly tuned vented enclosure above the ported tuning frequency. Advantages of a vented enclosure *Increased output around vented tuning *Higher power handling above the port tuning frequency *Extended frequency response *Magnet is in a good cooling environment *Handles higher bass frequencies with less distortion Disadvantages of a vented enclosure *Vented enclosure transient response is not as good as sealed boxes because of the resonant effect of the vent tuning *Midrange sound coming from inside the enclosure through the vent can produce unpleasant sound coloration. *Loss of cone movement control below vent tuning, which can result in...
