Immersive 7.1.2 sound with Dolby Atmos and DTS:X:

Polk MagniFi Max AX SR is a complete 7.1.2 soundbar system designed for movies, TV, music and gaming. The soundbar uses a total of 11 drivers, including dedicated up-firing height channels, while two wireless surround speakers provide sound from behind. Together, the system supports Dolby Atmos and DTS:X, allowing compatible soundtracks to be reproduced with height, width and surround information.

Polk SDA technology, Stereo Dimensional Array, also works to create a wider and more detailed stereo image. The result is a soundbar system where the front, height and surround channels work together to create a more spacious soundstage than a conventional soundbar alone. The system also supports formats including Dolby TrueHD-based Atmos, DTS-HD Master Audio and DTS Virtual:X.

Wireless rear speakers and powerful 10" subwoofer:

The two included surround speakers connect wirelessly to the system and each feature a 73 mm full-range driver. This provides separate physical rear channels without requiring signal cables from the soundbar to the rear of the room. The surround speakers can also be wall-mounted using their threaded inserts or keyhole hangers.

The wireless subwoofer uses a 10" driver in a ported enclosure with a down-firing design. Placement is more flexible because the audio signal is transmitted wirelessly, while BassAdjust lets you adjust the bass level. For dialogue, the system combines a dedicated centre channel with Polk VoiceAdjust. This feature allows voices to be emphasised relative to the rest of the soundtrack, making dialogue easier to follow without similarly increasing the volume of effects and music.

Streaming and flexible sound settings:

MagniFi Max AX SR can be used as a wireless music system via both Wi-Fi and Bluetooth 5.0. Wi-Fi streaming supports Apple AirPlay 2, Google Chromecast for Audio and Spotify Connect, as well as Works with Alexa. This provides several ways to stream music directly from compatible phones, tablets, computers and streaming services.

For different types of content, the system offers dedicated settings for movies, TV and music that adjust elements including bass, clarity and soundstage. Night Mode is designed for listening at lower volume levels and reduces bass while enhancing dialogue. This helps keep speech clear without the strongest bass impact. The system also supports control via compatible Google Assistant and Alexa devices.

HDMI eARC and connectivity for multiple 4K sources:

Three HDMI 4K inputs allow multiple sources to be connected directly to the soundbar and switched without a separate HDMI switch. The HDMI eARC connection handles audio from a compatible TV and supports high-bandwidth audio formats. Video pass-through supports 4K at 60 Hz, HDR and Dolby Vision.

An optical Toslink input is also available for TVs or other audio sources, while the USB-A port is intended for firmware updates. The soundbar can be positioned horizontally on furniture or mounted on a wall using the included wall brackets. At 114.3 cm wide, it is designed as a large soundbar with separate left, centre, right and height channels integrated into the cabinet.
