This full-range audio speaker features a compact design with a Ø52mm diameter and 28mm height, ideal for space-constrained audio applications. It offers a 4Ω ±10% voice coil impedance, supports 3W rated input power and 5W maximum input power, ensuring consistent performance. The minimum resonance frequency is 200Hz ±20%, with a frequency response range from FO to 20kHz for clear and balanced sound reproduction. At 3W input, it delivers a sound pressure level of 88±3dB, making it suitable for home audio-visual systems, car audio setups, intercoms, and Arduino-based DIY electronics projects. Its small form factor allows for easy integration and replacement in existing speaker enclosures.
