Our take on the Polk Audio MagniFi MAX SR

A common thread in our customer reviews for this Polk system is the ease of setup and use. In almost no time at all (and with minimal wires), you too can have true 5.1 home theater surround sound. With the MagniFi MAX SR you get a streamlined sound bar with a seven driver array, a powerful wireless sub, and two wireless surrounds for a truly immersive experience.

The wireless sub and surrounds make setup simple — they just need AC power.

Surround sound made easy

A common thread in our customer reviews for this Polk system is the ease of setup and use. In almost no time at all (and with minimal wires), you too can have true 5.1 home theater surround sound. With the MagniFi MAX SR you get a streamlined sound bar with a seven driver array, a powerful wireless sub, and two wireless surrounds for a truly immersive experience.

You also get 4K pass-through, plenty of connectivity options, and a few cables to boot (HDMI, optical digital, and stereo minijack to be precise). Even the wall-mount brackets are included, though you'll need to buy the appropriate fasteners for your wall type in order to use them.

Simple, yet powerful remote control

This unassuming remote is actually fairly full of cool features. You have independent bass control, surround sound volume and balance, and Polk's patented VoiceAdjust technology for crystal-clear dialogue. And if you'd rather not have to think too much about it, there are five sound-optimizing EQ presets: movie, sports, night, music, and all stereo.

The first three are fairly obvious to pick out, but you have to go deep into the manual to learn that the music note button actually toggles between the All Stereo and Music modes. This might resolve the issue some of our customers had with the sound quality of two-channel audio.

Great sound. No wires

Crutchfield Customer Review (What's this?)

My wife said "no wires across the room" and I didn't want to fish the walls but I really missed true surround sound. Now I have it back and the sound is excellent. I feed the sound bar from the TV using the optical audio cable only so the sound is whatever the TV is seeing instead of feeding the TV from the sound bar via the HDMI(ARC) given where I have the TV installed over my fireplace. I like the quality of the sound and the control I can have over it.

Pros: Excellent sound, easy setup, easy use.

Cons: I do wish it kept me informed as to which setting I have it on with the lights instead of only when I change it.

Crutchfield Customer Review (What's this?)

First of all Crutchfield got it to me in the 2 days like they said. This thing came in it's own retail box, so I am glad I was home when it got here. Major advertisement of what would have been on my porch. It was packaged incredibly well. This system is so easy to set-up it's crazy. The quality of the sound and the number of features is incredible for this price. The wireless surrounds and the wireless woofer connected immediately on their own. The setup of the wifi through Google Home was easy and fast, the bluetooth was smooth just like any other bluetooth device. This thing has some bass! I listened to 10 mid-range to upper end soundbar systems at a local store. NONE even came close to this one. I had planned to buy a cheaper system for half the price, but once I heard this one, I could have never settled for less.

Pros: easy setup, great sound

Cons: Had to pay the price for this one because after I heard it, no others compared.

Great Overall Product

Anonymous from Maryland on 3/26/2018

Crutchfield Customer Review (What's this?)

Overall a great sound bar for the money. I was able to setup via HDMI ARC to my Sharp TV which supports HDMI CEC. So my TV and my Comcast cable remotes can control sound, and the volume level is displayed on the TV as it had been before the sound bar. Considering the low cost of the system, the sound it is very good. Furthermore, you can really tweak the sound to your liking as there are volume controls for the subwoofer, the surround speakers, voice, and overall. And the different modes for Movie, Sports, Night, and Music make a discernible difference. As others noted in their reviews, the Night mode is particularly useful in quieting the system while keeping the dialog of a show very understandable. In fact, when I used the built in TV speakers the sound was distracting to others in the house while being hard to understand for those watching TV. With this system, it can actually be quieter in the other rooms while more impactful for those watching. In terms of negatives, I think the physical design of the unit has some limitations. It's designed to look great placed on a table in front of the TV. But in my case I mounted it underneath my TV using a mounting bracket from Mounting Dream that allows the soundbar to connect to the TV's VESA holes. The bar doesn't use a keyhole system, but uses some small brackets which require two screws per side. I got it to work fine, but both aesthetically and functionally it's not as good as other bars for under TV mounti

Pros: Sound tweaking via remote, 3 input HDMI's with ARC, CEC and 4K support. Good sound. Night mode. Great pre sales support from Levi at Crutchfield! Wireless surround and subwoofer make install easy.

Cons: Better for table top placement rather than mounting under a TV. Polk support said the bar had keyholes on the back when it did not. But was still mountable under the TV using the brackets provided and a soundbar mounting bracket.

Amazing sound in an easy package

Steve from Bethel, ME on 3/23/2018

Crutchfield Customer Review (What's this?)

Pros - Sounds absolutely amazing. I mean really amazing. In my opinion can't be beat for the price. It literally shakes my house and is very clear and crisp. Easy set up. Movie/sport/music modes work fantastic. Chromecast built in works excellent especially as I have chromecast whole home audio. Cons - no way to mount the soundbar, the remote being able to control other devices is nice but would be nice to be able to be turned off as sometimes the remote ends up turning something off I did not want turned off. Sometimes takes a little long to reconnect to source once switched to a different source. For example switching back over to take over my tv audio if it has previously been used for say HDMI couputer input. I do suspect this may be my tv though.

Excellent, robust sound for the price point that is at. Polk does a wonderful job with various adjustment options to ensure clear dialogue without sounding too artificial. The subwoofer and rear speakers do not skip a beat with no lag whatsoever from what I can hear, and provide fantastic low frequencies from the subwoofer, as well as great ambient, subtle sounds from the rears. I watched Blade Runner 2049 in 4K HDR and was blown away by the punch that this set up produced, and I didn't even have to push it to maximum potential. If you're in the market for a 5.1 system that has minimum wire maintenance without giving up sound quality, I say go with this product.

Neat surround effect, NOT good for music

Sean from Durham, NC on 1/27/2018

Crutchfield Customer Review (What's this?)

I purchased this with the recommendation of a Crutchfield employee. This soundbar has an always-processed sound that widens the frontal soundstage. That widening is effective for movies (usually) but is both distracting and non-preferred when listening to music. I was listening to a live recording of a female vocalist, and because of the ambient crowd sound and reverb, the vocals were hardly discernible. My iPhone speaker produced clearer dialogue in this example. Think of how music-heavy movies could be impacted by odd-sounding orchestra scores. This soundbar gets loud enough (more than loud enough) and setup was easy. DTS and Dolby Digital compatibility is very nice. The small surround speakers only need to be wired via the power supply. It did reliably stay connected to the network for Google music usage. Another Google-compatible speaker on my network often dropped off. I had this connected to an Oppo UHD player and LG Oled. Take it from an audio aficionado: Only use this for TV and movie viewing.

Pros: Discrete DTS and DD surround sound; Good interface with TV via HDMI ARC; Low-profile; Convenient remote functions.

Cons: 3D-type audio processing ALWAYS on; Muffled vocals with live music; Subwoofer does not produce deep bass; Loose bass.

Rob from Seattle, WA on 1/21/2018

Crutchfield Customer Review (What's this?)

This is one of the few soundboard available with wireless surround speakers, so there isn't much to compare it with. It's better than similar Vizio models, for what it's worth. Setup was straight forward. Sound is good for a system at this price point, although I wish it were a bit more rich- sometimes it can sound slightly tinny. I'm happy with my purchase overall, but I do wish the sound was just a little better.

Pros: Easy setup Attractive Very minimal

Cons: Sound could be a bit better

When it works the way it is supposed to it performs very well. Very unfortunately it does not always work as it is supposed to. The speakers have static and occasionally the is a loud bang sound. If the speakers are cycled on and off (disconnect the plug) it again works until the problem comes back again. Is it related to the 4 month delay in release ?

Pros: When it's working correctly it is very good.

Cons: It does not always work correctly. All speakers must be powered off and then on again to fix the problem temporarily.

Crutchfield Customer Review (What's this?)

Probably is my unit but I have experience issues with the subwoofer and the satellite speakers disconnecting randomly, even after using different inputs, cables and TVs. Sound quality is not there, no differences between highs and lows. The "center channel" is a great idea on a sound bar but the left and right are so muddy that is just confusing. The subwoofer and the satellite speakers, when they work, are adequate for this system no overpowering, I will say they are the best part of this system. Good idea but disappointed with the product.

Pros: Great idea, great concept

Cons: poor connectivity with satellite speakers, Not crisp at all

Good Equipment To buy

The Sound equipment has great and nice body finishing. one thing l love about it is very portable and easy to set up

Pros: easy to to setup and it works well when connected to TV, nice design, chrome cast connection was easy and most of all the entire equipment come fully wireless that make it easy to control wires all over the place. The equipment is a good sound to buy

Cons: it does not play sound warning to indicate the system are pair to two satellite speakers. l really hard time to get the two small satellite speakers to connect working to work together, the volume is not that too great but is a nice equipment to buy. sub woofer is great

Dennis from Philadelphia, PA on 1/10/2018

Crutchfield Customer Review (What's this?)

I was looking for a wireless surround solution for my bedroom as it is impossible to run wires do to the nature of my house. Tried Heos (hated it) thought about Sonos (like the product just too expensive) and then Polk came out with this. Up until now I have not really liked sound bars but what the hey its only my bedroom. I was very pleasantly surprised in this system. For a sound bar it sounds great. Love the simply plug into power Sub and surround speakers and they just work with no configuring. No OSD display or much in the way of EQ control which would have been nice. At the time of writing no Logitec Harmony Elite profile.

Pros: Wireless Sub and surrounds Wireless speakers just worked out of the box. Looks pretty

Cons: No On screen display Poor EQ control No room acoustic mike

Good all in one wireless system

Rand from Ft Collins, CO on 1/6/2018

Crutchfield Customer Review (What's this?)

Just got this and set it up today so with time I may figure more out. The basic set up is fine and it works. The speakers synced automatically. No speaker wires! Must have a independent power outlet for each speaker. I love how much control there is for the surround speakers with volume and balance control right on the remote. I think the sub-woofer is lacking in defined base and strength. Volume is overall adequate for a sound bar but not real strong. I think the overall quality of the sound is pretty good for the entire system but some adjusting is needed between different input types. I think the instructions for connecting a cable or satellite device (which most people still have) is poor. Unsure if the cable should go first to the sound bar or through the TV then to the sound bar. Could only get it to work through the TV then to the sound bar. Very little in the instructions for using Wi Fi properly. The Google Home App was not that helpful in getting it connected to Wi Fi or controlling it. Unclear how to use Chromecast. I could not find a menu that comes up on the TV screen. I have not yet found a downloadable manual - only the quick start instructions. Will keep playing with it but a detailed instruction manual would be really helpful. I am glad to know Crutchfield will have my back!

Pros: Nice easy to sync completely wireless speakers.

Cons: Limited instructions. Sub-woofer is not great.

Good Sound, Could Use DD+ Support

Anonymous from New York, NY on 1/3/2018

Crutchfield Customer Review (What's this?)

Very easy setup, no issues with pairing/syncing wireless sub or surrounds. Sounds great to me, perhaps not as good for music as the wired 5.1 setup I had before, but not much different - I do wish there were a bit more options for fine-tuning or calibrating the sound though. Had some issues with the sub making popping noises, but that seems to have resolved after moving the sub away from my wifi router - I'm assuming it was wifi interference. My main issue is that it does not seam to support Dolby Digital Plus decoding - I have to call Polk to confirm, but I'm not seeing 5.1 as an option on Shield Android TV apps outputting DD+, so the soundbar does not seem to be identifying itself as able to decode DD+ - I had tried a cheaper Vizio 5.1 setup before returning it due to poor sound quality, and the Vizio was able to detect/play 5.1 DD+ signals without issue.

A Bit Disappointed

Lee from Wellington, FL on 12/30/2017

Crutchfield Customer Review (What's this?)

I've had this for about a week now, and my results are mixed. John Wick 2 on Cinemax sounded very good. Great screeching and punches, lots of crash'em up. Dialogue (for what that's worth in this movie) was clear, cut through the effects well. The surrounds were crisp with quick response. (Some bars I know have significant lag getting the signal to the wireless rears.) Tuned over to War Dogs on HBO and the sound was just fine. There's more music track on this movie and the Polk handled it admirably. So why am I not more pleased with it ten days in? I wanted to watch a year-end review on MSNBC, and it felt as if the sound floor collapsed. Checked a few other channels (w/DD) and it's the same thing. Totally flattens out, directionless to the point I would swear it was out-of-phase. There is no way to fatten up the sound, and this is discouraging. The three sound fields options don't help. I understand this is still a soundbar, not a five speaker setup where you'd need movers. (also still not able to get Polk power off through the Comcast XR11 remote.)

Pros: Unboxing and setup are a breeze, comes complete with everything you'd need including HDMI and Optical cables. Well thought out design. DD 5.1 material sounds very good.

Cons: Conventional two channel TV programs sound lost and hollow.

Perfect - Ideal for Condo living

Cheryl from Boca Raton, FL on 12/30/2017

Crutchfield Customer Review (What's this?)

We pre-ordered this and eagerly await it for our small Florida condo. It arrived, very well packaged, and it has been a joy. We installed it in the preferred manner, by effectively having the soundbar act as the central controller. HDMI inputs go into it from our Roku Ultra (4K) box, and it is connected to the LG 4K TV via HDMI-ARC. (We are not using the TV's optical output as that is slightly less capable). It works wonderfully in playing music and video from our Sony UBP-X800 4K Ultra HD Blu-ray Player too. I appreciate its standard movie mode, and voice mode, and it was not at all hard to set up. I have not yet tried, but am looking forward to the night time mode which provides voice enhancement at lower volumes, when playing movies at night in the condo - to not bother your neighbor. The surround sound emulation provided by the soundbar is quite capable - you can definitely tell it, in movie mode. And, yes, our subwoofer works well even placed across the room. We don't need driving bass, but felt it quite a bit in an adventure move. Oddly enough, the only thing I am giving up is the highest fidelity I used to enjoy with my turntable and older expensive speakers specifically chosen for listening to classical music/orchestral works using my older Denon audio receiver. There, the soundbar is not as good, but certainly adequate. I suspect opera lovers may also feel the difference. Most jazz sounds very good. We bought from Crutchfield, and this solved our problem exactly.

Pros: sound quality, support for wide array of sound encodings, works with HDMI-ARC. Supports 4K

Cons: can't replace a dedicated audio-only system particularly for instrumental works


Justin from Henderson, NV on 12/29/2017

Crutchfield Customer Review (What's this?)

Ok so far fairly decent but requires some initial effort in order to get it working right. Also, I have found one MAJOR FLAW once you have everything working; which specifically makes you press the corresponding HDMI 1, 2 or 3 on the remote depending on which source you initially which to watch. For some reason it does NOT DEFAULT to HDMI 1; so when I turn on my TV and soundbar there is no picture right off the bat; thus requiring me to then select the proper HDMI button on the remote for whichever source (ie cable, dish, bluray etc.) I wish to watch. This should be automatically detected and it is not. So essentially when I first turn on my TV there is NO picture displayed from a default HDMI source; rather I have to hit on the soundbar remote HDMI 1, 2, or 3 depending on what I want to watch - STUPID! When you first try to link all of the wireless speakers and sub it's a little confusing; as you have to press the button on the soundbar and then each button on each speaker for 10 seconds each; and only when BOTH speakers are paired will you hear a confirmation tone. You will not hear a confirmation tone for each rear speaker, only for both once the are done together. You MUST install Google Home App on your phone to search and find any firmware updates; another DUMB IDEA IMO. UPDATED 1/4/18: TOP NOTCH PHONE SUPPORT DIRECT FROM POLK - EXCELLENT AUDIO - AND FINALLY AWESOME SOUND! Had a few issues during the first week of setup regarding hdmi switching; come to find out that it was solely due to my error in plugging the hdmi sources into the soundbar instead of my TV. The issue was that my tv was using CEC settings and conflicting with the soundbar - essentially from making things operate smoothly. After being contacted directly by Alex at Polk; he carefully and thoughtfully listened to my issues and provided me solutions that worked perfectly! He also educated me on a feature that everyone needs to be aware of. When watching TV you basically have 3 sound choices on your remote. Movie mode which gives you a cinematic sense of sound OR if you press the musical note button on the remote once - you are in 2 channel mode - WAIT FOR IT....... BUT when you hit the music button a SECOND TIME - out pops your sound in all it's glory in 5.1 channel awesome audio! Folks that have been leaving not so great reviews about the muddled sound - I guarantee that this is exactly why you may have been experiencing such issues. I unfortunately do find the movie mode to sound a bit muddled as many suggest; however once in 5.1 mode by hitting the musical note button on the remote 2 times - the 5.1 sound will immerse you in audio bliss as it should. Sadly Polk kind of messed up on this one; as there should have been separate 2.1 and 5.1 buttons on the remote control - and they should NOT be tied to a musical note symbol as this is very confusing; leading one to believe that it is for music listening only. I did not even see any mentioning of this dual button mode fe

Pros: Sound is pretty darn good, but depends on the quality of your video source material for sure! It's the ONLY system out their that's compact and has 4K HDMI pass-through and HDCP 2.2. Nobody else has this in this price point with rear speakers as well. Rear speakers are loud and clear.

Cons: Very few available sound settings tweaks - essentially bass & treble and balance up and down and rear speakers and sub volume. That's it!

Sound is better than the tv.

I waited 3 months for this and it looks good but does not work with my Sony . The HDMI function will not work. The only option is the optical cable and the input switching built in to the tv. Plus you would think it would have some on screen graphics.

Pros: Better sound than the TV

Cons: The HDMI does not syc with my new Sony TV. Also no front panel lights to tell you what is going on.

Troy from Bentonville, AR on 12/24/2017

Crutchfield Customer Review (What's this?)

Utter piece of crap. I was really looking forward to receiving this item as my new living room setup isn't conducive to running speaker wire for surround speakers. With Polk's good name, I thought that this setup would be a winner. For starters, it just sounds cheap. If you like a bunch of muddy midrange tones, this may be your cup of tea. If you'd like some spatial seperation between the lows, midrange and highs, then maybe you'd better keep shopping. Secondly, it feels cheap. The subwoofer has the look and feel of a subwoofer that comes with a cheap computer speaker setup for under $100. I'll experiment with placement some more, but right now it's just muddy. Perhaps this wouldn't matter if there were controls to adjust the settings, but all you've got is a bass up/down and a voice up/down control. You can also adjust the volume of the surround speakers relative to the soundbar, so you've got a choice of whether you want all of the muddiness up front or more of it coming from the sides. Bitterly disappointed.

Pros: Wireless surround speakers Easy setup--speakers synced automatically

Cons: Lousy--and I do mean lousy--sound. Very little sound adjustment options Cheap feel

Active Soundbar Speaker: The Polk MagniFi Max SR features a low-profile, slim-design soundbar speaker. The soundbar speaker is equipped with a seven speaker array which consists of two 0.75" tweeters, one 1" midrange driver, and four 1"x3" oval-cone full-range drivers, all powered by a 180W (RMS)/360W (Peak) built-in amplifier for dynamic sound. Twin side-firing ports aid in low frequency response.

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 8" woofer, down-firing bass port, and built-in 160W (RMS)/320W (Peak) amplifier. You can independently adjust the wireless powered sub's bass level from the rest of the system's overall volume level.

Wireless Surround Speakers: The Polk MagniFi Max SR comes with two Polk SR1 wireless rear speakers to create a truly immersive, multi-dimensional 5.1 surround sound experience. Each wireless speaker features a 3" mid-woofer with built-in amplifier.

Proprietary Polk Technologies: Featuring Polk's patented SDA surround sound and Voice Adjust technologies, the MagniFi Max SR soundbar speaker system produces an immersive listening experience.

  • SDA (Stereo Dimensional Array): Polk's patented Stereo Dimensional Array (SDA) surround technology creates an expansive multi-dimensional soundstage and detailed stereo image. SDA both heightens and widens the soundstage providing an immersive room-filling sound without sacrificing clarity. SDA also compliments Dolby & DTS encoded content creating an incredible cinematic experience.
  • Voice Adjust: Voice Adjust technology dramatically increases vocal clarity and volume level for crystal clear dialog no matter what you're watching. You can customize the voice levels in the soundbar however you prefer to reproduce clear, crisp dialog and never miss a single word of your favorite movie, TV show, or sporting event.

Optimized EQ Presets: EQ settings for Movies, Music, All Stereo, Sports, and Night optimize the soundbar and subwoofer to ensure you get the clearest dialog, big surround sound, and deep bass for the best audio and home theater experience regardless of what you are watching or if you are watching late at night.

  • Movie: Acoustically optimized for both movie and TV soundtracks. It also provides a bass boost, increased spatialization and enhances Voice Adjust levels for improved dialog clarity. It is the default sound mode for HDMI and Optical input sources.
  • Music: Music mode gives you balanced sound and smoother bass while minimizing spatialization effects to ensure more natural sound reproduction.
  • All Stereo: All Stereo mode provides room-filling sound by mirroring the front left and right channels to the surround left and right speakers.
  • Sports: Enhances dialog-rich content, like sporting events, news casts, and talk shows.
  • Night: Reduces bass and volume dynamics while improving voice intelligibility for low-volume listening.

Dolby Digital & DTS Compatible: The Polk MagniFi Max SR soundbar speaker system will decode Dolby Digital & DTS audio (up to 5.1ch) through its HDMI and Optical digital inputs. 2ch PCM audio is also supported through HDMI, Optical, and stereo minijack.

ARC (Audio Return Channel): This feature of the system's HDMI output allows audio to be sent from your ARC compatible TV to the MagniFi Max through the same HDMI cable already being used to send audio and video to your television. This eliminates the need for extra cables connected to your TV. The HDMI ARC output supports Dolby Digital 5.1ch & 2ch PCM.

Note: Because with many televisions, the ARC-enabled HDMI input will only pass 2ch PCM from devices connected to the TV via HDMI or analog, we recommend that you connect your Blu-ray player, satellite/cable box, and game system to the soundbar system's HDMI inputs directly; and then connect the soundbar's ARC-enabled HDMI output to your TV's ARC-enabled HDMI input. This setup will give you with the best overall sound performance.

Digital & Analog Audio Inputs: In addition to HDMI connectivity, the Polk MagniFi Max SR soundbar system provides a digital (optical) input and analog minijack (3.5mm) input for connectivity to your TV or other source components. You should make sure to turn your TV speakers off or set to "0."

  • 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 & DTS 5.1ch program material. The soundbar's digital input also supports 2-channel PCM.
  • Stereo Minijack Input: The soundbar is equipped with an analog stereo minijack (3.5mm) input to connect your television (which may lack an optical digital output). If your TV is equipped with stereo RCA outputs, you will need a stereo minijack-to-RCA adapter cable (sold separately).
Note: 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).

Video Section

HDMI 2.0a: Featuring three HDMI inputs and one HDMI ARC output, the Polk MagniFi Max SR incorporates an advanced video section that features the latest HDMI 2.0a 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 SR supports up to 4K (3840x2160 pixels) video on all of its HDMI inputs and 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) HDR format.

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.

Bluetooth & Chromecast Built-in

Network Connection: The Polk MagniFi Max SR offers built-in dual-band (2.4/5GHz) WiFi (802.11 a/b/g/n/ac) and features a rear-panel Ethernet (RJ-45) jack for a wireless or wired connection to your home's network router. By connecting to your home's network, the MagniFi Max SR will support Chromecast Built-in, so you can wirelessly stream many of your favorite music apps from your Apple iOS or Android device, Mac computer, or Windows PC to the soundbar speaker system.

Chromecast Built-In: Chromecast built-in lets you cast many of your favorite music apps from your from your Android (OS 4.0+) or Apple iOS (8.0+) device, Mac computer, Windows PC, or Chromebook to the MagniFi Max SR soundbar speaker system. Chromecast built-in certified apps include Tidal, Spotify, Pandora, TuneIn, GooglePlay Music, YouTube Music, & iHeart Radio (click here for a complete list of compatible apps - subscription fees may apply). Chromecast built-in streams your music directly from the cloud instead of from your smartphone or tablet, so you don't lose any sound quality. Additional Chromecast built-in features include -

  • Simple-to-Use: Chromecast built-in allows you to search, browse, play, skip, and turn up the volume directly from the music apps you know and love on your compatible phone, tablet or laptop. While you cast your music, you can still use your smartphone to answer a phone call, play a game, send a text, and even leave the room, all without interrupting what's playing on the receiver's speaker system or draining your battery. Friends and family can even use their own Chromecast Built-in compatible phone or tablet to cast music to your system by connecting to your home's WiFi network.
  • Google Home: Multiple Chromecast built-in speakers can be added to the same WiFi network to form a multiroom audio system using the Google Home app. Using the Google Home app (for Apple iOS 9.1+ and Android OS 4.0.3+), you can sync multiple speakers with Chromecast built-in in multiple rooms of your home to play the same song throughout your house at the same time. Only Chromecast built-in compatible music apps are supported.
  • Voice Control (Optional): Purchase the Google Home Wireless Speaker (sold separately) or other Google Home Assistant compatible speaker (see Accessories tab) and gain voice control of compatible Chromecast built-in music apps. You'll be able to access a specific music app and then select a specific station or song using only your voice. You'll also have voice control over Play, Pause, Skip, & Volume. The MagniFi Max SR & the Google Home Assistant device must be connected to the same wireless (WiFi) network.

Bluetooth Audio Streaming: The Polk MagniFi Max SR soundbar system supports Bluetooth A2DP which allows you to wirelessly stream audio from your Bluetooth-enabled smartphone, tablet, laptop, or desktop computer. You'll be able to stream stored music, music apps, podcasts, audiobooks, and other audio content from your Bluetooth source device to the soundbar speaker system. Basic playback control (such as Play/Pause, Previous/Next Track, & Volume Up/Down) can be done from the included IR remote. You will continue to use your Bluetooth source device for advance music navigation and to view song/artist information.

Note: The MagniFi Max SR does not support Bluetooth hands-free communication for phone calls.

Other Features

Remote Control: The included IR remote control provides wireless operation of the Polk MagniFi Max SR soundbar speaker system. There are also several ways to use your TV, cable, or satellite remote to control the MagniFi Max SR system.

  • HDMI CEC: If your TV is connected to the MagnFi Max via HDMI and your TV supports HDMI CEC, you can control the volume and mute functions of the soundbar speaker system from your TV's remote control.
  • Polk Smart Remote Technology: Polk Smart Remote technology allows for most Samsung, LG, Vizio, and Sony TV remotes to control the MagniFi Max's volume and mute functions right out of the box (no programming required). TV must be manufactured within the last 5 years.
  • IR Learning Function: If you have another brand of television that is not listed above, or you have a cable or satellite receiver, you can also program the MagniFi Max SR soundbar speaker system to respond to one of these remotes (remote functions include - Power, Volume, and Mute).

Top-Panel Controls: The following controls are found on top of the soundbar speaker - Power, Source, Volume, Mute, Voice Adjust, and Bluetooth Pairing.

Mounting Options: The Polk MagniFi Max SR offers flexible mounting options for the active soundbar speaker and wireless powered subwoofer.

  • The soundbar speaker should be centered under or above your flat-panel TV screen. The soundbar can simply be placed on a tabletop, stand, or shelf (integrated rubber feet provide secure placement). The soundbar can also be mounted to the wall using the included wall-mount brackets (mounting screws not included). The unique wall-mounting system provides horizontal adjustment to ensure the soundbar remains level and centered under your TV.
  • The powered subwoofer receives its signal from the soundbar wirelessly, so it can be placed virtually anywhere in the room (up to 30' from soundbar). Ideally, the powered sub should be placed along the same wall as the soundbar speaker. Placing the powered subwoofer in a corner will increase its bass response even more.
  • The wireless surround speaker can be simply placed on a stand, shelf, or table-top. You can also wall-mount the wireless surround speakers using the built-in keyhole slots (mounting screws not included). In addition, each speaker includes a 1/4"-20 threaded insert for use with articulating wall-mount brackets (sold separately). Theses speakers are designed to be mounted horizontally (not vertically) and are marked "Left" &  "Right". Left/Right balance controls allow for asymmetrical placement.

Power Requirements: The active soundbar speaker, wireless powered sub, and two wireless surround speakers will all require an AC power outlet. The soundbar speaker includes an AC power adapter with attached 58" DC cord and a detachable 58" AC power cord. The powered sub comes with a detachable 69" AC power cord. Each wireless surround speaker comes with an AC power adapter with attached 9.75' DC cord.

Polk quality [ Billy  Mar 14, 2018 ]
Price and Polk reputation. Some not so positive reviews, but, that is to be expected. I know that Crutchfield has an excellent return policy, that with a $100.00 off makes it an easy decision. [ GC  Mar 10, 2018 ]
Recommended by trusted audiophile who said for the money this was a great system. [ Daryn  Jan 30, 2018 ]
good reviews [ Jay  Jan 10, 2018 ]
Wanted wireless surrounds [ Dennis  Jan 02, 2018 ]

5 questions already asked

No. It has slots that let it drop onto the included brackets. They are custom to this bar, as far as I can tell. The brackets would attach to the wall and the sound bar rests on them. [ ANDREW  Apr 06, 2018 ]
I should wake up before answering questions. Yes it does have keyhole slots a both ends just like a traditional fluorescent light fixture. My apologies [ Duane  Apr 06, 2018 ]
I misread your question, I was looking at the mounting bracket for the surround satellite speakers. I have not gotten to wall mounting, may never do that in preference to placement in front of my eventual 4K Ultra HDR 50" curved [ Duane  Apr 06, 2018 ]
No. There is a drop down square slot about 1.5 X 4 inches. You supply the bracket to wall screws etc [ Duane  Apr 06, 2018 ]
I have yet to get the Bluetooth function to work. Until Inget a smart TV I'm using my Roku to run Youtube and the cast to the Roku from my IPad. It's smashing then, I mean a YouTube has it all figured out [ Duane  Apr 06, 2018 ]
I cannot respond to the question as I don't attempt to use the Chromecast feature. I do cast video from my PC to the LG television which then plays the audio through the Polk system. Sorry if that isn't much help. [ Louis J  Apr 04, 2018 ]
I didn't want to drive my video through the Max so I only connect my Max to the TV with the TV's optical audio out and feed it to the Max. Hence, once configured on the TV, it plays any sound the TV gets from either the internet, or either HDMI source. I cannot respond to other configurations. [ Louis J  Apr 04, 2018 ]
As long as you hook all your components through the TV and then hook the TV to the sound bar through hdmi arc then everything plays through the soundbar. [ JORDAN  Apr 04, 2018 ]
You connect the soundbar to your TV through the HDMI(ARC) and then set the TV sound to external speakers. You can also stream music/audio from other devices to the sound bar by Bluetooth. Excellent sound in both cases! [ Jay  Apr 03, 2018 ]
It works for hdmi and you can use the optical cord... both included! As for OTA... it does have a WiFi signal it gives off that you have to set up by downloading the google cast app... has Bluetooth as well... it does audio in and audio out! Such a beautiful device!!! [ Steven  Apr 03, 2018 ]
have no idea. Only have smart tv and dvd hooked up. Dish is my service [ michael  Apr 03, 2018 ]
You can have the bar plugged to your tv through hdmi arc Or optical and have all of your devices plugged to your tv (chromecast, roku, cable) and have your tv send the sound to the bar. This gives you the option of tv speakers or sound bar. Alternatively you can connect all of your devices to the bar and use it like a receiver to switch between devices. [ Donald  Apr 03, 2018 ]
The soundbar accepts audio return from the TV via HDMI ARC. It works well with my Samsung TV, using the Netflix app on the TV for example. The soundbar can also take audio from the TV via RCA or Optical but HDMI ARC is the way to go. [ Patrick  Apr 03, 2018 ]
It does have an optical input if your TV has one [ Terrence  Apr 03, 2018 ]
As you adjust the volume on the Max (as opposed to from the TV) you can see reference lighting change from a single light to multiples as you go, but the steps are very small and you must be paying attention. (I am specifically referring to using the Polk remote not the television's. [ Louis J  Apr 04, 2018 ]
There is a 10 LED array on the front of the bar. It indicates volume, bass, voice adjust, and surround speaker levels. It also is used to show left right balance of the rear surrounds if you are connecting via HDMI CEC, you should see volume level on your TV (this is function of your TV and HDMI CEC not the MAX). [ Michael  Jan 15, 2018 ]
It supports both HDR-10 and Dolby Vision. You will find this information, and more, by clicking the "Details" tab on the speaker's main webpage and scrolling down below the "Features & Specs" table. (It's also listed on the Features & Specs table) I hope that helps. My bio: [ Ryan  Jan 05, 2018 ]  Staff
