The Polk Audio MagniFi MAX SR is a 5.1 setup with a sleek design. It comes with a discrete subwoofer and two satellites. It has a Stereo Dimensional Array surround sound feature advertised to help create a more immersive sound, though we don't test for this. Also, it has a Voice Adjust dialogue enhancement feature, and you can adjust its volume to customize the dialogue performance based on your preferences. This soundbar scored well on many of our sound tests, conducted using a sine wave tone to measure frequency response. However, we noticed several issues when listening to real-life content like music and movies. Audio seemed diffused and processed at times, and we noticed very audible port noises when listening to bass-heavy tracks. There was also a lot of compression and distortion present, especially in the bass range. We even had connectivity issues with the Google Home app. Though we retested the bar and updated the firmware, we experienced the same problems. It seems that many other users have reported similar issues with the bar, which you can read about here, here, and here.
Our Verdict
With its 'Music' preset, the Polk Audio MagniFi MAX has a somewhat U-shaped sound profile when listening to real-life content, making it suitable for listening to most types of audio content. Voices reproduce clearly and accurately, and you can enhance them using the unique Voice Adjust feature. However, audio can seem diffused and processed, and you may notice port noises and compression when listening to bass-heavy audio content. It doesn't support Dolby Atmos content, either.

While you can wirelessly stream podcasts and audiobooks to the bar via Bluetooth, Wi-Fi, and Chromecast built-in, unfortunately, it doesn't support Apple AirPlay.

With its 'Music' preset, the Polk Audio MagniFi MAX has a somewhat U-shaped sound profile when listening to real-life content, so there's a little extra emphasis in the bass range while vocals and lead instruments are bright and sparkling. It's suitable for listening to most music genres, although the port noises and compression when listening to bass-heavy content may not be ideal for fans of genres like EDM and hip-hop. While you can adjust its bass level, there aren't a lot of other customization features available.

Test Results
The Polk Audio MagniFi MAX SR is a sleek, stylish soundbar with a somewhat unique design. It's mostly plastic, and there's fabric covering the front and top of the bar. There's also a golden ring surrounding the center channel. On its ends, there are open passive ports.
The Polk Audio MagniFi MAX's sub is mostly plastic and sits on four pegs with rubber grips. The port and the speaker are located underneath.
The Polk Audio MagniFi MAX's satellites have a similar design to the bar. They're mostly plastic, with fabric covering the front and the top. There's also a small Polk Audio logo on the front.
The Polk Audio MagniFi MAX SR is wide and likely won't fit between the legs of a 55" TV stand. That said, it also isn't very tall, so it shouldn't block your TV screen unless your TV sits flush on your table.
The sub is a bit larger than some of the others we've tested, but it shouldn't take up much more room than an average desktop computer.
The satellites are a bit wide and tall, but they connect to the bar wirelessly, so you have more flexibility when placing them in your setup.
The Polk Audio MagniFi MAX SR has a decent build quality. The bar and the satellites are both mostly plastic, which feels pretty solid and durable. The fabric coverings are tight, so it's unlikely that they rip easily. However, they still seem prone to collecting dust over time. The subwoofer is also mostly made of plastic.

The Polk Audio MagniFi MAX SR scores well on our stereo frequency response tests, conducted using a sine wave tone. However, when we listened to the bar with real-life content, we noticed that it doesn't perform as well as the score suggests. With some audio, it had a pretty neutral sound profile on its 'Music' preset, suitable for listening to most types of audio content.
With other content, we noticed a U-shaped sound that adds extra emphasis in the bass and treble ranges. As a result, audio has extra thump and punch, and vocals and lead instruments are bright. Audio could also seem a bit diffused and unnatural, and there are noticeable port noises when listening to bass-heavy content.
The Polk Audio MagniFi MAX SR has a great stereo frequency response with calibration. With its bass set to '-1', it has a very neutral, balanced sound profile suitable for listening to many different types of audio content. We conduct this test using a sine wave tone, and we noticed some inconsistencies in the bar's performance when listening to real-life content like music and movies.
The Polk Audio MagniFi MAX SR has a decent stereo soundstage. The soundstage is perceived to be wider than the bar itself, which is good. However, we noticed that the bar tries to push the sound, which can sound diffused and processed, especially around the far edge of the soundstage.
The Polk Audio MagniFi MAX SR gets loud enough to fill larger, more open rooms with sound. However, when you push it to max volume, there's a lot of compression in the bass range that's quite noticeable with real-life content. Sound seems like it's forced and lacking control. You'll want to listen at a more moderate volume for a more natural sound with less compression.
The Polk Audio MagniFi MAX SR comes with a discrete center channel, which helps to more accurately localize voices within the stereo image. Its frequency response is quite balanced, so voices reproduce clearly and accurately. However, the bar is lacking bass on its center channel. It may not be too noticeable with real-life content, though, since there typically isn't much bass reproduced on this channel.
The Polk Audio MagniFi MAX SR comes with two discrete surround speakers, which help to more accurately localize sound objects like voices and footsteps within the sound image. When conducting our surround channel tests using the sine wave tone, we noticed a lot of bass, and the subwoofer overpowered the satellites. It wasn't very noticeable when listening to real-life content, however.
The Polk Audio Magnifi Max AX SR is a good alternative for a soundbar with Atmos support.
The Polk Audio MagniFi MAX SR has a poor selection of sound enhancement features. It has a Voice Adjust feature that enhances dialogue by making it more clear and crisp, and you can even adjust the volume level for this feature using the controls on the bar. There are a few EQ presets to help you customize its sound, including 'Music', 'Stereo Dimensional Array', 'Movie', and 'Sports'. The 'Stereo Dimensional Array' preset is advertised to help create a wider soundstage. This soundbar lacks some more premium sound enhancement features like room correction, so it may sound a bit different depending on the room you're listening in.
The Polk Audio MagniFi MAX SR has several physical inputs. There are three Full HDMI In ports, meaning that you can use the bar as a hub between different devices like your PC and your TV. There's also an AUX port, so you can use the included AUX cable to wire older devices to the bar for audio playback.
Over its ARC port, the Polk Audio MagniFi MAX SR supports both Dolby Digital and DTS content. These surround sound formats are commonly found on Blu-ray discs and streaming platforms.
The Polk Audio MagniFi MAX SR only supports Dolby Digital via Full HDMI In. Dolby Digital is the most common surround sound format, so this should be suitable for most users who like to watch Blu-ray discs. That said, it's disappointing for users who want to watch lossless and object-based formats like Dolby Atmos.
The Polk Audio MagniFi MAX SR supports Dolby Digital and DTS content via Optical, commonly found on Blu-ray discs and streaming platforms.
Latency falls within good limits over an ARC connection. You can listen to common surround sound formats like Dolby Digital without any noticeable lip-synching issues. Some apps and TVs compensate for latency differently, though.
You can also enjoy videos and movies over HDMI In without latency issues. The audio you hear is in sync with the visuals on screen. Since some apps and TVs compensate for latency differently, you may notice some differences with real-life use.
Latency falls on the higher side over an Optical connection. Our results indicate a likelihood of some lip-synching issues with videos and movies. However, it isn't quite as noticeable with real-life content as the numbers suggest. Apps or TVs may compensate for latency differently.
This soundbar can passthrough many common resolutions and refresh rates, which is handy if you want to use it as a hub between devices like a PC and a TV. Text on the screen appears clear and crisp as a result. It also supports high-quality video signals like HDR10, HDR10+, and Dolby Vision, so you can passthrough from gaming consoles and Apple TVs. It can't passthrough variable refresh rate technologies like ALLM, though, which is disappointing if you like to use these for a tear-free gaming experience.
The Polk Audio MagniFi MAX SR has incredible wireless playback support. You can wirelessly stream audio from your mobile device to the bar over Bluetooth, Wi-Fi, and Chromecast built-in. However, some Apple users may be disappointed by the lack of AirPlay support.
The Polk Audio MagniFi MAX SR doesn't have a display. Instead, lights flash different patterns when you change the input and adjust the volume. They turn green when you're listening to Dolby Digital content and yellow when listening to DTS content.
On top of the Polk Audio MagniFi MAX, there are some physical controls you can use to power the bar on/off, change the input, mute the bar, and adjust the volume for Voice Adjust as well as your main audio.
