Four 3 W 8 Ω speakers for compact projects

This pack contains four miniature full-range drivers rated at 3 watts and 8 ohms each. They measure 31 mm long, 28 mm wide and 15 mm thick, making them suitable for tight enclosures. The units are designed for use with Raspberry Pi, Arduino and similar small electronic builds. Each speaker arrives new and ready to install.

Passive drivers with 11 cm 2.0 terminal leads

As passive components the speakers draw no power themselves; thermal load and noise depend entirely on the driving amplifier. The 11 cm two-pin 2.0 terminal cables allow straightforward wiring without soldering. A one-to-two interface lets the builder select either 3.3 V or 5 V logic levels for the control side. No active cooling or fan noise is introduced by the drivers.

Replaces larger single drivers

These speakers upgrade from bulkier units when enclosure depth is limited to roughly 15 mm. The jump is worth it when a project needs four discrete sound points or a stereo pair in a portable device. They are not suited for applications requiring higher output power, lower impedance loads or integrated amplification. Builders needing more bass extension or volume should look elsewhere.

Questions about this item

How do I connect the 2.0 terminal to a 3.3V or 5V supply?

The 11 cm lead ends in a one-to-two separating connector; plug the pin that matches your supply voltage into the board and leave the other pin unconnected.

What part of the speaker is most likely to need replacement after long use?

The 3 W voice coil can overheat if driven continuously at full power, so the speaker itself is the component that eventually fails.

What thermal limit appears first when the speaker runs at 3 W for extended periods?

The 31 mm by 28 mm by 15 mm cavity has no heatsink, so the voice coil temperature rises until the insulation degrades.
