Soundbar Speaker RB-M28008G-003AR

The RB-M28008G-003AR soundbox speaker is engineered to deliver exceptional audio performance with reliability and durability. With dimensions of Φ31.3*12.0mm and weighing 17g, it strikes a balance between compactness and robustness, making it suitable for various applications.

Featuring Nd-Fe-B magnet material and a magnet size of Φ13.5×2.0T, this speaker offers a nominal impedance of 8 ± 15% Ohm at 1000Hz and 1V, ensuring compatibility with a wide range of audio devices. It has a power

rating of 2W (normal) and 3W (maximum), providing ample power for clear and immersive sound reproduction.

The RB-M28008G-003AR offers a frequency range of 240±80% Hz and a sound pressure level (SPL) of 80±3dB, delivering balanced and dynamic audio across a wide spectrum of frequencies from FO to 20,000Hz.

To ensure consistent and accurate sound reproduction, this speaker undergoes a normal test using a 4.0V sine wave across a frequency range of 50~5kHz. Additionally, its polarity is verifiedby observing the movement of the diaphragm when a positive DC current is applied to the voice coil terminal marked + or red.

Operating reliably in temperatures ranging from -20°C to +55°C and storage temperatures from -25°C to +65°C, this speaker undergoes rigorous testing procedures to ensure its performance under extreme conditions. It is subjected to temperature, humidity, vibration, and drop tests to evaluate its resilience and durability.

The RB-M28008G-003AR is capable ofwithstanding white noise for 96 hours at 2.0W input power, as well as exposure to high and low temperatures and humidity levels. It is also tested for vibration resistance and durability against drops onto concrete floors.

With its compact size, powerful performance, and robust construction, the RB-M28008G-003AR soundbox speaker is an excellent choice for applications where reliable and high-quality audio reproduction is essential.
