3W 4 Ohm Stereo Enclosed Speaker – Compact Mini Speaker with 2P 2.0 Terminal Wire

The 3W 4 Ohm Stereo Enclosed Speaker is designed for adding compact audio output to electronic projects. The enclosed housing makes it convenient for installations where a protected speaker assembly is preferred over an exposed speaker driver.

Its 4Ω impedance and 3W rated power make it suitable for compatible low-power audio amplifier circuits. Always ensure that the amplifier is designed to operate with a 4Ω speaker and does not exceed the speaker's rated power. Enclosed 3W/4Ω speakers are commonly used with small amplifier modules and embedded audio applications.

Features

• 3W rated audio power.
• 4Ω speaker impedance.
• Enclosed speaker chamber.
• Compact design for space-constrained projects.
• Pre-attached terminal wiring.
• 2P 2.0 terminal connection.
• Suitable for small audio amplifier modules.
• Easy to integrate into DIY electronics projects.
• Suitable for embedded and portable audio applications.

Applications

• DIY electronics projects.
• Portable audio devices.
• Embedded audio systems.
• IoT devices.
• Arduino and microcontroller projects.
• Raspberry Pi audio projects.
• Educational and robotics projects.
• Mini multimedia systems.
• Voice-output projects.
• Alarm and notification systems.
• Small audio amplifier projects.

How to Use

1. Check that the amplifier supports a 4Ω speaker load.
2. Turn off the amplifier power before making connections.
3. Connect the speaker wires to the amplifier's speaker output terminals.
4. Ensure the positive and negative connections are correctly matched where polarity matters.
5. Keep the amplifier output within the speaker's 3W rated power.
6. Secure the speaker enclosure properly to prevent unwanted movement or vibration.
7. Power the amplifier and gradually increase the audio level.

Important Notes

• This is a speaker, not an amplifier. It requires a suitable audio amplifier or audio-output circuit.
• Do not connect the speaker directly to a high-voltage power supply.
• Use an amplifier designed for a 4Ω load.
• Avoid exceeding the 3W rated power, especially for prolonged periods.
• Excessive volume or amplifier clipping can cause distortion and may damage the speaker.
• The actual sound level and frequency response depend on the amplifier, enclosure installation, audio source, and mounting conditions.
• The term "stereo" in the product name should not be interpreted as two separate speaker channels unless the supplied product configuration specifically contains multiple speaker units.
• Connector and wire appearance may vary slightly between batches.
• Product images may be illustrative.
