I’ve built homemade speakers using various materials for the cone. This design is the best. Paper plates are too soft, and disposable plastic cups vibrate too much, but stiff, lightweight styrofoam produces sound quality that competes with commercial speakers. I really mean it — you will be surprised!

Step #1:
- Cut 2 strips of paper, ½"x11" each. Coil one strip lengthwise around the magnet and tape it closed, but don’t tape the paper to the magnet.
- Roll the other strip around the first one and tape it closed as well, but don’t tape it to the first roll.
- Remove the magnet.
