The MagniFi MAX SR 400W 5.1-Channel Soundbar and Wireless Surround System from Polk Audio includes the MAX sound bar, wireless subwoofer, and two wireless surround speakers. Compatible with most TVs via HDMI ARC or optical, this soundbar system delivers room-filling home theater sound via Dolby Digital 5.1. VoiceAdjust and surround sound technologies make for clear, crisp dialogue and immersive listening, while the included wireless subwoofer deepens the bass impact. With the MagniFi MAX SR you can wirelessly stream your favorite music directly from your compatible mobile device through Bluetooth and Chromecast built-in.

Surround Sound

A seven-driver array, the included wireless subwoofer, and the SR1 wireless surround speakers create immersive multi-dimensional sound via Dolby Digital 5.1, DTS, and Polk SDA surround technology.

Adjustable Wall-Mounting

The wall-mounting system allows for horizontal adjustment to ensure the soundbar remains level and centered under your TV.

Voice Adjust Technology

Customize the voice levels in the soundbar however you prefer to reproduce clear, crisp dialogue and never miss a word of your favorite movie, TV show, or sporting event.

Wireless Music Streaming

Featuring built-in Wi-Fi, Chromecast built-in, and Bluetooth, the MagniFi MAX SR allows you to stream music directly from your smartphone, tablet, or other compatible device.

Deep Bass Technology

The MagniFi MAX SR soundbar and the included 8″ ported wireless subwoofer give you a boost of core-pounding deep bass impact that takes home theater and music listening to a new level.

Movie, Music, and Sport Modes

One button preset EQ settings for movies, music, and sports optimize the soundbar and subwoofer to ensure you get the clear dialogue, big surround sound, and deep bass for audio and home theater experience. Sports mode is suitable for news and talks shows, too.

Universal Compatibility

The MagniFi MAX SR works with most TV, cable box, or satellite IR remote controls, so there’s no need for two remotes.

Night Mode

Don’t wake your family or neighbors and stop straining to hear the evening news. With Night Mode, one button lowers the bass and increases Voice Adjust to deliver clear dialogue without raising the master volume.
