This 40mm diameter speaker cone is the perfect addition to any audio project where you need an 8Ω impedance and are using 0.5W of power. We particularly like this cone as it's very simple and its plastic body is extremely lightweight and thin. Originally designed for 'talking' greeting cards, its fairly loud yet lightweight.
