How to Build an Economical Speaker Box
Speaker boxes are used to house several component subwoofers and other speakers in an enclosure. Although most subwoofers are sold separately, you might want to put them into one box or enclosure hence the use of a speaker box. Speaker boxes are not hard to build but are very challenging for if done correctly they can help enhance the output of stereo source. For those who are not so good with craftwork can certainly order the sub woofers already pre-enclosed.
What is needed in order to build a speaker box?
It all depends on your budget and intent of the speaker boxes. You have to determine the size and the materials used. The best material that you can use is a ¾ inch medium density filter board. If you have the cash to spare, you can opt for more exotic materials but most people use fiberboard.
Aside from the fiberboard, you will also need: a jigsaw (a bladed cutting power tool), a power drill, a spiral but, a ¾-inch bit, a router, sand paper, spray glue, solder gun and ammo, Solder D-sub Connectors, and some carpet if you want to cover the speaker box.
Most subwoofers on the market come with a set of optional instructions that let you design an enclosure for it. No need to figure out the dimensions when a set of measurements have already been included in the package. In this case it means that you won’t have to go through trial and error designing an enclosure since it has the common specs for most speaker boxes.
One important thing you have to realize is that if the measurements are given on an interior measurement, you might have to adjust the measurements by as much as ¾-inch.
It is also ideal to trace your desired design and size measurements on the filter board rather than doing any freehand cutting. Avoid using markers for they can be unsightly if the speaker boxes are not covered with carpet.
For obvious reasons, you have to use your jigsaw to cut the design and not a knife or other cutting tool. The jigsaw lets you curt clean and neat. Once the pieces have been cut out, it is a good idea to make a trace of where the speakers would go into. In order for you to do this you would have to use a router. Once you have used the router to cut the holes, you would have to use sand paper to smoothen the holes made.
You should also look into creating holes so that the necessary cables can pass through. If the template or instructions do not have any notes for holes, it is best to create 2 inch holes on either side of the speaker box. Always sand them through so that there are no snags when done.
After the holes have been cut, you can now assemble the boards together. Using screws, nuts and washers, you have to make sure that they fit tight and don’t rattle. Always leave the front of the box last so that any last minute works can be dealt with.
The next part is the easiest for all you have to do is out the subwoofers in, close the front panel, and plug the power and Solder D-sub Connectors in.
The real workload is in the construction of the speaker box and that being said, you have to make sure that the work done is up to precise and exact.
