CRITICAL EVALUATION OF IN-CAR SOUND Alpine’s top engineers from all over the world gathered in Alpine headquarters to deeply research and evaluate sound systems from both the aftermarket and high-end OE manufacturers. Many systems today have incredible dynamic range and reach sufficient volume levels, but lacked the reality of instruments and spatial imaging. As a result, Alpine ID was born, a sound philosophy that continues to inspire us to create a new level of sonic performance. ALPINE: IMAGE DEFINED Or Alpine ID for short, is the new Alpine global sound culture with an evolutionary approach for solving what’s missing in most car audio systems these days: great spatial imaging and depth of sound stage.
