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!
Jargon buster
Plain-language definitions for the technical terms used above.
- Impedance
- Impedance is the total opposition a component or circuit presents to alternating current, measured in ohms, combining resistance with frequency-dependent reactance. It appears in many contexts, such as matching a speaker's impedance (for example 4 ohm or 8 ohm) to an amplifier or the input and output impedance of signal circuits, and a correct match helps avoid weak signals, distortion or damage.
