AI Sound Boost
The Xtreme 4 utilizes AI Sound Boost to enhance its audio performance in real time. By analyzing the incoming audio signal and predicting speaker movement and power response, the AI algorithm optimizes dynamic range, increases volume and bass, and reduces distortion. This allows the Xtreme 4 to push its drivers to their full potential, delivering powerful and immersive sound.
