You can also sand the edges after if you want. I used a heavy duty cut off wheel and multiple passes to cut the edges off the enclosure. Use a dremel or similar cutting tool to cut your enclosure at the predefined dimensions. *Dont forget to account for the volume of your sub and any support bracing etc that will be taking up "volume" inside the enclosure as this will count against the total volume. This is the volume your enclosure should be. Mark the leven that the material reaches in your enclosure with a sharpie. Fill the container of known volume then pour the contents into your fiberglass enclosure. In this case it is about 1 cubic foot of space*.īecause we have a complex shape for our sub enclosure, how do we determine the volume of the enclosure? A simple way to calculate volume for an irregularly shaped enclosure is to create a similar enclosure of a known volume (eg a rectangle) and fill it with packing peanuts, sand, or anything else that will fill the volume and is easy to manage.
Since we are making a sealed enclosure we only care about the sealed enclosure volume of our specific driver. Each subwoofer driver has specific enclosure volume for sealed and ported enclosures. You have the subwoofer driver or the "sub" and the enclosure. Subwoofers are really two parts that interact to create a low frequency sound.
