Sound Modes
Optimize your audio experience with preset sound modes for movies, music, and night listening. Night Mode reduces bass and enhances dialogue for late-night viewing without disturbing others.
VoiceAdjust Technology
Polk's patented VoiceAdjust technology allows you to customize voice levels for crystal-clear dialogue without affecting the overall soundtrack. This is particularly useful for complex audio mixes in movies or TV shows.

SDA Technology
Polk's patented Stereo Dimensional Array (SDA) technology creates a wider, more immersive soundstage by acoustically canceling interaural crosstalk, making the sound appear to come from beyond the speakers.

Troubleshooting
If you encounter issues with your Polk Audio MagniFi Max AX SR system, refer to the following common troubleshooting steps:
