Listen up! This 1.5" diameter speaker cone is the perfect addition to any audio project where you need an 8Ω impedance and are using 0.25W of power. The speakers are rated at 0.25W, with a maximum input of 0.5W (printed wattage on back of speaker may have either value).
Adafruit 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.
Works great with Adafruit's Wave shield or class D amplifier board. Just be careful not to overdrive the speaker as high volumes can blow it out! Start with lower volume and increase carefully.
