Get to know this product.

Ultra-Compact System For Powerful, Room-Filling Sound

At an amazingly compact 15 inches wide, MagniFi Mini AX leverages 50 years of Polk loudspeaker engineering and an advanced five-speaker array and powerful subwoofer to upgrade your TV sound with deep, impactful bass, crystal clear highs, and an expansive 3D soundstage rivaling much larger sound bars.

Dolby Atmos, Done Better

Experience a level of cinematic surround sound that you’d never expect from a 14.5” sound bar via certified Dolby Atmos and DTS:X that’s optimized in MagniFi Mini AX with our patented SDA technology for an even wider, more accurate soundstage. In addition, 3D Audio Mode transforms stereo audio to 360-degree surround sound.

Enjoy Higher Quality Music Streaming

Enjoy higher-quality music streaming from your phone, tablet, or computer over Wi-Fi with Apple AirPlay 2, Google Chromecast, and Spotify Connect. Easily connects to devices via Bluetooth, too.

Hear Every Word

Tired of riding the volume control? Never miss a word of dialogue again. Polk’s patented VoiceAdjust™ speech-clarifying technology works synergistically with MagniFi’s integrated center-channel speaker to bring up the level of voices without affecting the rest of the soundtrack.

Downfiring Subwoofer for Maximum Bass Impact

MagniFi Mini AX includes a powerful down-firing subwoofer to deliver Polk's legendary, effortless bass for maximum impact in movies, music and gaming. This compact subwoofer connects wirelessly for convenient placement.

One-Click To Optimize Your Sound

Preset sound modes optimize MagniFi's bass, clarity, and soundstage for movie watching or music listening with one click. Enable Night Mode to turn up the dialogue and turn down the bass for late-night watching, without disturbing the neighbors.

Expandable Surround Sound

Add Polk SR2 wireless surround speakers (available separately) to get even more immersion with full, multi- dimensional 5.1 surround sound.

Enjoy Great Sound In Minutes

Get to your movies and music faster with one-cable setup and universal compatibility.
