Hear the good news! This speaker is a great addition to any audio project where you need a 4 Ohm impedance and 3W or less of power.

At 40mm diameter it has a more square-ish shape, but a smaller face. Sound quality and volume are nicely sandwiched between our Thin Plastic Speaker with Wires and the honkin' 20W 4 Ohm Full Range Speaker.

This bite-sized speaker comes with two long color-coded wires to solder to or plug into a breadboard!
