How Do You Build A Fiberglass Subwoofer Enclosure?
Fiberglass is strong, lightweight, and can be shaped into a variety of forms — perfect if you’re considering building a custom subwoofer box. Take it step by step, and you can build a box that you’ll be proud of. Design your enclosure. Carefully measure the area you’ll use for the box. When determining the size and shape of the box you want, it’s important to check the specifications of the subwoofer you’ll be using. Most subwoofers are designed to perform best in a box of a specific volume, so size the design of your box accordingly. Build a form for your box. Using two-part construction-grade polyurethane foam, create the rough shape you want for your box. When the foam has hardened, file it into the desired shape using a “cheese-grater” style file. When you’re satisfied with the rough shape, work out any external blemishes with finer files or sandpaper. Apply the fiberglass onto the foam form. Long strips of mat work best if you have a lot of curved surfaces. Follow the instruction
