2Pcs – 1.5 Inch 4 Ohm 3W Mini Round Speaker

Description: 1.5″ (≈40 mm) 4 Ohm 3 W Mini Round Speaker – Typical Details

Basic Specs:

• Size: ~1.5 inch diameter (~40 mm) — very compact for small audio applications.
• Impedance: 4 Ohm — low electrical resistance, good match with small amplifiers.
• Power Handling:
  
  • Rated Power: ~3 W — continuous power it can comfortably handle.
  
  • Max Power: can be slightly higher for short bursts (often up to ~5–6 W depending on the model).
• Frequency Response: wide-range (often ~200 Hz to 20 kHz) for full range audio.
• Sensitivity: typically ~83 dB ±3 dB — louder output per watt.
• Weight: light and easy to mount.
• Construction: usually dynamic driver with paper or PU cone and small magnet for sound reproduction.

Typical Features & What It Means:

Full-Range Sound

These speakers are designed to reproduce most audible frequencies (mid-range and highs) fairly well for their size —though bass will be limited due to the small cone size.

Low Impedance (4 Ω)

4 Ohm impedance lets them draw more current from an amplifier compared with higher-impedance speakers. Good for small amps designed for low-ohm loads.

Compact Applications:

Ideal for:

• DIY speaker builds
• Portable Bluetooth or mini audio devices
• Embedded sound in toys, alarms, instruments
• Arduino/raspberry pi audio projects and small electronics

Typical Use & Installation:

• Usually solder wires to speaker terminals or use small connector leads.
• Best in a small enclosure for improved sound performance.
• Pair with a small amplifier board (2–6 W class) for clear output.
