Fill your room with Atmos sound

The MagniFi MAX AX SR sound bar system offers big sound with support for detailed multichannel formats like Dolby Atmos and DTS:X. The bar packs an impressive 11 built-in speakers that direct sounds for greater immersion, including up-firing drivers for overhead effects.

A wireless subwoofer adds weight and impact to your movie and game soundtracks, helping you feel the action on-screen. And wireless surround speakers produce true wraparound effects so you can hear the action behind and around you.

Music streaming options aplenty

If you want to chill and listen to music, this bar has you covered with built-in Wi-Fi, Bluetooth, Chromecast built-in, and Spotify Connect. With all these options, it's easy to wirelessly stream your favorite tunes from your phone directly to the sound bar. Need to decompress after a long day? You're just a couple swipes away from the Black Keys' "Just Got to Be" — and that always seems to make the evening feel a little smoother.

Apple fans are in good hands, too. AirPlay 2 lets you stream using an iPhone® or iPad® and connect the sound bar to the AirPlay ecosystem. If you're a subscriber to Apple Music®, you can even use Siri to control and play that service with your voice.

Deep, no-hassle bass

The included 10" subwoofer connects wirelessly to the sound bar for easy placement and setup. Just turn it on and hit "Connect" on the back of the sub. With a ported cabinet that delivers extended bass, this sub helps bring the rumble to your favorite movies and games.

Don't miss the quiet moments

Quiet conversations can sometimes get lost in the mix of a movie or game's soundtrack. We've all strained our ears at some point to catch important lines. The MagniFi MAX AX SR has a dedicated center channel to bring conversations front and center. And Polk's VoiceAdjust™ technology lets you further boost voice levels to make sure you're consistently getting clear, intelligible dialogue.

Polk Audio MagniFi MAX AX SR sound bar and subwoofer system

Wireless surround speakers are easy to set up and have a clean look that blends into the background of your room.

Streamlined controls

The sound bar includes a remote with simple, intuitive controls. But it's also pre-programmed to work with most TV remotes currently on the market. No scrambling for the right remote — you can just use the one already in your hands.

The MagniFi MAX AX SR's preset sound modes also help you make quick adjustments with the press of a button. There are presets for movies, music, and watching TV at night when the kids are down for the count.

Expanded sound

This sound bar system includes a pair of surround speakers that deliver true, wraparound rear-channel effects for deeper immersion. The speakers also connect wirelessly to the sound bar, so you only need to plug in to an AC outlet instead of running speaker wire across your room.

11-Driver Array Soundbar: The Polk Audio MagniFi Max AX SR is a 3.0.2ch active soundbar speaker with dedicated front, center, and height channels for an accurate and expansive soundstage. The dedicated front, center, and height channels are made up of an 11-driver array that combines Polk's patented technology to deliver Dolby Atmos and DTS:X surround sound - up to5.1.2ch with the included wireless powered subwoofer and wireless rear speakers.

  • Stereo Front Channels: The active soundbar's stereo front channels consist of a total of six drivers. There is one 0.75" soft-dome tweeter and two 3" x 1" racetrack mid-woofer drivers for each left & right front channel.
  • Dedicated Center Channel: The soundbar dedicated center channel consists of a total of three drivers, including a 0.75" soft-dome tweeter and two 2.5" x 1" racetrack mid-woofer drivers.
  • Discrete Height Channels: The soundbar speaker's discrete height channels consist of two 2.5" full-range drivers on top of the speaker cabinet that fire upward and reflect sound off the ceiling for overhead effects from Dolby Atmos and DTS:X movie soundtracks.

Wireless Rear Speakers: The included Polk SR2 wireless rear speakers help create a truly immersive, multi-dimensional surround sound experience (up to 5.1.2ch). The rear speakers connect wirelessly to the soundbar, so you don't have to run cables or wires from the soundbar to the rear speakers (they do still eachrequire an AC power outlet). Each Polk SR2 wireless speaker features a 3" mid-woofer with built-in amplifier to deliver surround effects from your movie soundtracks.

Note: Simply press the "Connect" button on the back of the wireless speakers and soundbar to pair them together.

Wireless Powered Sub: The included wireless powered subwoofer reproduces deep bass impact that you can feel from your movie and music soundtracks. It houses a down-firing 10" woofer, down-firing bass port, and built-in amplifier. You can independently adjust the wireless powered sub's bass level from the rest of the system's overall volume level. This powered subwoofer connects wirelessly to the soundbar for convenient placement (it does still require an AC power outlet).

Note: The powered subwoofer automatically pairs to the soundbar when powered on and connects wirelessly.

SDA 3D Audio Technology: The Polk MagniFi Max AX SR can create room-filling Dolby Atmos and DTS:X surround sound (up to 5.1.2ch), enhanced with Polk's patented SDA (Stereo Dimensional Array) 3D audio technology. Polk's patented SDA 3D Audio technology creates an expansive three-dimensional soundstage and detailed stereo image. SDA both heightens and widens the soundstage providing an immersive room-filling sound without sacrificing clarity. A Movie Mode adds this same virtual width and height dimension to any movie or music soundtrack for an immersive listening experience. In addition to Dolby Atmos and DTS:X, the MagniFi Max AX SR supports Dolby Digital, Dolby Digital Plus, Dolby TrueHD, DTS HD, and DTS.

  • Dolby Atmos: Dolby Atmos creates powerful, immersive audio with sound that comes from all directions (including overhead) to fill your home cinema with astonishing clarity, richness, detail, and depth. Dolby Atmos brings to life a movie's soundtrack with sound that flows all around you in three-dimensional space to completely immerse you in the action, heightening your cinematic experience.
  • DTS:X: DTS:X places sound in a movie soundtrack where it would occur naturally in space, creating a truly lifelike, multi-dimensional audio experience. DTS:X replicates a real-world sound environment that transports you (the audience) into a new dimension of sound immersion by delivering a truly captivating home cinema experience.

Sound Modes: You can cycle through a variety of sound modes to adjust the audio characteristics of the soundbar system according to the type of content you are listening to or simply your preference. The sound mode setting is saved for each individual HDMI input/output to allow you to tailer the sound for each source input.

  • Auto: This mode automatically sets the most appropriate sound mode for the media that is currently being played back.
  • TV: Use this mode for casual TV and movie watching. This mode helps you hear all the important dialog and affects even at low to moderate volume levels.
  • Movie: Use this mode for an enveloping and dynamic movie theater experience regardless of the content. This mode enhances the height and surround effects in Dolby Atmos and DTS:X audio formats and virtualizes these effects for other program formats
  • Music: Use this mode for streaming music or for enhancing musical content in TV shows and movies.
  • Night: Use this mode for low-volume listening. This mode reduces bass and volume dynamics while improving voice intelligibility.
  • All Stereo: Use this mode when listening to music to send the front left and right channels to your surround speakers. This mode is only available when the Polk SR2 surround speakers are connected.

Audio Adjustments: Using the included IR remote control you can customize the MagniFi Max AX SR soundbar system's Voice, Height, Bass & Treble, as well as Surround level.

  • VoiceAdjust: Polk's patented VoiceAdjust speech-clarifying technology works with MagniFi AX's integrated center-channel speaker to bring up the volume of voices over other elements of the movie soundtrack. Voice Adjust technology dramatically increases vocal clarity and volume level for crystal clear dialog no matter what you're watching.
  • Height Level: The Height Adjust feature lets increase or decrease the volume level of the dedicated up-firing, height-channel speakers on the MagniFi Max AX SR soundbar.
  • Bass & Treble: From the remote control, you can adjust the soundbar system's Bass & Treble. You can increase or decrease the high frequency details, as well as increase or decrease the amount of impactful bass.
  • Surround Control: You are able to raise or lower the surround output level of the wireless rear speakers.

HDMI eARC: The Polk Audio MagniFi Max AX SR can connect to your TV via HDMI eARC or HDMI ARC (depending on the capability of your TV). For optimum performance, use an HDMI eARC connection. eARC stands for enhanced Audio Return Channel and allows full-resolution sound signals, including Dolby Atmos and DTS:X, to be passed from your TV to the soundbar system.

  • eARC (Enhanced Audio Return Channel): If you connect to a TV with eARC, the multichannel audio formats supported include Dolby Atmos (uncompressed), Dolby TrueHD, Dolby Digital Plus, Dolby Digital, DTS:X, DTS HD, and DTS.
  • ARC (Audio Return Channel): If you connect to a TV using ARC, the multichannel audio formats supported are dependent on your TV model and manufacturer. The TV may be capable of sending Dolby Atmos (compressed), Dolby Digital Plus, Dolby Digital, and DTS. An ARC connection cannot support Dolby TrueHD, DTS HD, or DTS:X.

Optical Digital Input: The soundbar features a single optical (toslink) digital input to connect your flat-panel TV. The optical input can decode and reproduce Dolby Digital and DTS program material. The soundbar's digital input also supports 2-channel PCM.

  • The digital optical output terminals of many newer flat-panel TVs only send an audio signal in 5.1ch when receiving Dolby Digital/DTS surround sound from the TV's built-in tuner, network connection, or connected USB device; and will output only 2ch stereo from sources connected to the TV via HDMI, or RCA (like your Blu-ray/DVD player or satellite/cable box).
  • There are no analog audio inputs.
Video Section

HDMI 2.0b: Featuring three HDMI inputs and one HDMI eARC output, the Polk MagniFi Max SR incorporates an advanced video section that features the latest HDMI 2.0b specification, including support for 4K Ultra HD video pass-through, High Dynamic Range (HDR) video, and HDCP 2.2 compatibility.

Note: There are no analog video inputs or outputs.

4K Pass-Through: The MagniFi Max AX SR supports up to 4K (3840x2160 pixels)/60Hz video on all of its HDMI inputs and HDMI eARC output. It will also pass a 480i, 480p, 720p, 1080i, or 1080p video signals via HDMI. There is no video resolution upscaling.

HDR (High Dynamic Range): HDR (High Dynamic Range) provides enhanced picture quality by simultaneously enabling greater detail for both the dark and bright parts of an image. HDR reproduces a greater dynamic range of luminosity or brightness levels, creating greater contrast. This increased contrast reveals the subtle nuances of the image, from detailed blacks and shadows to the brightest whites and colors, plus greater depth. The MagniFi Max SR supports two types of HDR formats - HDR10 and Dolby Vision.

  • HDR10: HDR10 is an open standard and currently the most popular HDR format on the market. It supports 10-bit color and 1,000 nits. It uses static metadata at the start of a movie to tell the soundbar and your TV that the video content is encoded using HDR.
  • Dolby Vision: Unlike HDR 10 which contains static metadata, Dolby Vision utilizes dynamic metadata which adjusts brightness, color, and contrast automatically for each scene. Dynamic metadata carries information that maps every image to your TV's display capabilities, so you see more of what the content creator intended. Dolby Vision supports 12-bit color and 10,000 nits.
Note: The system does not support the HLG (Hybrid-Log Gamma) or HDR10+.

HDCP 2.2 Compliant: All of the soundbar speaker system's HDMI jacks are HDCP 2.2 compatible which fully complies with the latest copyright protection standard for 4K video transmission.

AV Sync: If the soundbar audio is out of sync with your TV dialog on-screen, you can manually adjust the timing using the AV Sync adjustment feature from the remote control.

Customer Q&A

8 questions already asked

Can you mount the soundbar to the tv?
todd  Jan 09, 2024
1 answer
Greetings Todd. Thank you for your question. It does not come with any brackets to mount to a TV. Could you get creative and fabricate a mount, and bolt it to the back of your TV, sure. There are also mounts for bars that go in between the TV and a wall mount for the TV. In that case the bar tilts, and or swivels with the TV and the mount. We have those listed under the accessories of the Polk bar.

Is there an app for the soundbar?
latham  Nov 25, 2023

Greetings Latham. Thank you for your question. Polk Audio does not offer a remote app for the Magnifi Max bars, just their Command series bars.
hogan  Nov 25, 2023 (Staff)
I know it says that this could be used without an AVR amplifier receiver, but can I use the speaker system with subwoofer with an AVR receiver if I choose to? My Denon receiver, AVR to be specific can I use this with my Denon?
mark  Oct 06, 2023
1 answer
Powered soundbars like the MagniFi MAX AX SR are not intended for use with an AVR. Aside from potentially using the AVR has an HDMI source switcher, there would not be a benefit to using an AVR alongside the soundbar.
zachary  Oct 06, 2023 (Staff)
I currently own the previous generation of this without Atmos and have always been a pretty big fan of Polk but I've been also seeing some great reviews of the JBL 9.1 system which on the surface seems comparable. I'm not seeing many (any) reviews out there on the SR AX, only the Magnifi Mini and I'v seen MANY great reviews of the JBL 9.1. Hesitant to move away from Polk but curious if anyone could offer some insight on what might be a better path to go? Thanks!

The Polk SR AX is an excellent system. I added the 2 surround speakers and the music filled the room.
daniel  Mar 20, 2023
The Polk Audio Soundbar Magnifi Max Ax Sr is very easy to set up. The sound is very balanced and quite good. Very good with music. Atmos is a 3.5 out of 5, it could have been a 5 of 5 if they put upward firing speakers in the surrounds. I don???t think you will get a better system at this price point.

I have not heard the JBL 9.1 but on paper it looks good and competitive in the price range. I got the Polk magnifi max ax sr for $700 on sale and that???s part of the reason I went with it. I think if you don???t mind the rechargeable rears or if you don???t have outlets available the JBL should be a good choice. Mostly positive reviews. Good luck

I have not seen very many reviews of this Polk Magnifi max ax sr anywhere online. How would this unit stack up against something like the Klipsch 1200 and the top LG unit? I???m currently using a 2019 LG 8070 PUA TV and a Vizio M series sound bar that uses software tricks to mimicking atmos.

Hi Thomas, First, sound wise, I am not a Klipsch fan as I find them too bright for my ears. I recognize them as a great product but just not my hearing preference. I haven???t tried LG sound bars or speakers so I can???t help there, but??? Over a year ago I bought the Samsung Q950A(?) which was highly anticipated for its ATMOS abilities. While it was very good with movies, it made TV hard to understand as it didn???t seem to know where to send the voice to and where to cast it from. It sounded better in a bigger room but still I gave it to my kids and kept my previous Polk Magnifi Max with no ATMOS. My surrounds are mounted higher on the wall and the Polks outdid the Samsungs. Moving forward a generation, my surrounds are still higher and I haven???t tested them lower but it feels so much richer than the Samsungs ever felt. With them the Atmos almost seemed ???gimmicky??? where this feels genuine. It???s very full and frankly incredible for its size. And I can turn up the voice if needed (which I dont). And something else I really like is it recognizes the source so it automatically sets it???s settings to TV or 3D or whatever where it???s predecessor, I had to constantly hit the music or movie button. I have hardly touched the settings on the remote since my initial setup and sound testing other than to adjust the overall volume. In short, if you love Klipsch and have a great working system with the opportunity to have some height to your surrounds, I???d go with what you love vs. trying a ???new??? brand with ATMOS as it???s selling point. As a Polk fan, I highly recommend this and have not felt the ATMOS as ???gimmicky???. It feels more like it is just there and not overwhelmingly awesomely ATMOS???y. And to me, that is a good thing.

1. Can I use this soundbar, subwoofer and satelite speakers with 110V/60hz power supply? 2. In your article, you mention that it's a 5.1.2 system. But the official Polk website advertises this as 7.1.2 system. Which is correct? 3. If I play a 7.1 audio, will the L/R surround sound(not rear surround sound) come from soundbar or satellite speakers?

Greetings Tony, and thank you for your questions. If the power supply is regulated, and filtered, I see no issue, but you may want to confirm that with Polk Audio as we are not going test that. The official Polk Audio users manual has the MagniFI MAX AX as a 5.1.2 system. 7.1 audio input will play back in 5.1, or 5.1.2 just like a wired surround system.

How would this Max AX SR sound bar compare to a full Sonos Arc setup, with surrounds and sub?

This is hard to compare, Scott. Personally, I feel comparing this amazing Polk MagniFi MAX SR setup to the full Sonos surround package is a potentially unfair comparison. The addition of the surrounds is of course going to be a better performing package for the true totally immersive home theater experience. I think if we were comparing the Sonos ARC/SUB combo only to this it's going to be a similar performer. I would advise this Polk bar if you cannot put surrounds in your room, or you wish to have Atmos decoding and capabilities in a sleeker setup using just a bar and sub. Now I tend to love the surround channels the most in my own setups, so if you do want that total immersion something like the Sonos ARC/sub/surrounds setup in the link below would outperform the Polk simply due to the additional surround channels. I hope this helps!
