  • Polk Voiceadjust™- Hear Every Word
    Tired of riding the volume control to hear the dialogue during quiet scenes? Have trouble picking out voices when the bass kicks in? Polk’s VoiceAdjust was designed to make sure that you hear every word. This patented technology combines with Signa S4’s dedicated center channel to allow you to raise the volume of only the voices, making them clear and easy-to-understand, while leaving the rest of the soundtrack untouched.
  • Optimized Sound Modes
    One-button, preset sound modes optimize the Signa S4 so you can have the best sonic experience for movie watching and music listening.
