Polk DSP cancels out wind, water, and engine noises to keep your music front and center. Our DSP optimizes the audio signal to deliver only the most important sounds, ensuring a consistent volume without losing impact or letting in any unwanted noises. That means no audible hiss or interference when the volume is low and no distortion when you turn it up.
