Polk Audio’s unique VoiceAdjust technology in the MagniFi Mini AX Sound Bar helps viewers hear movie and TV dialogue without constantly changing the level. A detailed look into how this feature improves listening:

  • Improved Accessibility: This feature also benefits viewers with hearing difficulties, making it easier to follow dialogue without raising the overall volume to uncomfortable levels.

Integration with Overall Sound Quality
