This small, 2 W speaker is a compact way to add loud, high-fidelity sound (compared to typical units this size) that can bring your project to life. It includes four 1.0mm-diameter mounting holes. This is the highest-power speaker we carry.

This compact, general-purpose speaker is great for adding loud, high-fidelity sound that can bring your project to life (or to annoy your friends and family with loud sirens and squawks!). If you have an adequate driver for it, such as a small MOSFET controlled from a microcontroller PWM line, you can really get much more volume and richness than you can from similar-sized low-power speakers and buzzers.
