The onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer is a budget-friendly 5.1.2 bar. It's part of the Walmart brand's lineup, which includes several different budget-friendly soundbars that you can only purchase from the retailer itself. Unlike the brand's 36" 2.1 setup, it comes with a dedicated subwoofer to improve bass reproduction. Compared to its 36" 5.1 setup, it also comes with additional support for Dolby Atmos content. As a result, it's the most premium offering available in the lineup.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar is decent for mixed usage. The bar has a really bass-heavy and dark sound profile right out-of-the-box, but there are some adjustment features to help you customize its sound to your liking. You can balance out the mids, so voices in movies and TV shows are clear and present in the mix. There's also Atmos support, which is great if you watch a lot of movies on streaming platforms. That said, its Atmos performance isn't very impressive, even when compared to other budget-friendly bars. Not all of its features work, either, as its EQ presets can't change the frequency response for a different sound.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar is decent for dialogue-heavy content like TV shows. Using its subwoofer level and treble adjustments, you can get an even, neutral response, especially in the mid-range where most voices are reproduced. That means that dialogue is clear and detailed in the mix. Its discrete center helps localize those voices to clear points in the soundstage, too. However, unlike many other budget models, there's no dialogue enhancement mode, which is quite disappointing.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar is a decent choice for music. Out-of-the-box, it has a really bass-heavy and dark sound that overwhelms vocals in the mix, but you can use its treble and subwoofer level adjustments to customize its sound more to your liking. It gets really loud, so you can crank up the volume for parties. However, there's some compression at its max volume, meaning that audio isn't as clearly reproduced at loud volumes.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar is decent for movies. Once you adjust its frequency response, dialogue is clear and present in the mix, so you can hear the characters on your screen. However, since there aren't any surround speakers, its surround performance isn't the most impressive. It's one of the only bars in its price range that offers Atmos support, but its performance doesn't really stand out amongst the competition, since it fails to create a really immersive sound.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer is available in a Black variant with Grey fabric. You can see the label for the tested model here.
If you come across another version of the onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer, let us know in the discussions below so we can update our review.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer is a budget-friendly 5.1.2 setup. It's one of the few models in its price range with support for Dolby Atmos content, which is nice. That said, it lacks a lot of features, even when compared to other price-friendly models. For example, you can't enhance its dialogue, and its EQ presets don't change the frequency response, either, which is quite disappointing. Its Atmos performance isn't quite as good as the Polk Audio Signa S4 or the Vizio M Series M51ax-J6, either.

The Vizio M Series M512a-H6 is better than the onn. 42" 5.1. 2. Dolby Atmos Soundbar. The Vizio is a 5.1.2 setup with discrete satellites, and it has better surround and Atmos performances. Its soundstage is better, too, and unlike the onn, it has DTS support.
The Vizio SB36512-F6 is better than the onn. 42" 5.1. 2. Dolby Atmos Soundbar. They're both budget-friendly 5.1.2 setups, but the Vizio offers better surround and Atmos performances. It comes with discrete satellites, unlike the onn, and there are more sound enhancement features available. Also, it can reproduce a more extended low-bass to help you feel the rumble in action-packed movies and bass-heavy music.
The Sonos Arc is better than the onn. 42" 5.1. 2. Dolby Atmos Soundbar. The Sonos is a bit different, as it's a 5.0.2 standalone bar with a more premium design that you can upgrade with a sub and satellites down the line. Still, it has better soundstage, surround, and Atmos performances. There are more sound enhancement features available, too, and DTS support. It can't reproduce as much bass on its own compared to the onn.
The LG SP9YA is better than the onn. 42" 5.1. 2. Dolby Atmos Soundbar. They're both 5.1.2 setups with Atmos support, but the LG is more versatile. It's better-built with a better stereo soundstage.

The Vizio M Series M51ax-J6 is better than the onn. 42" 5.1. 2. Dolby Atmos Soundbar. They're both affordable 5.1.2 setups with Atmos support, but the Vizio soundbar's Atmos performance is better. The Vizio comes with discrete satellites for a better surround sound, too. There are also more sound enhancement features available and DTS support, which the onn lacks.
The Samsung HW-Q950A is better than the onn. 42" 5.1. 2. Dolby Atmos Soundbar. The Samsung is an 11.1.4 setup with discrete satellites and offers better surround and Atmos performances. Its soundstage is better, too, and it supports more sound enhancement features. Unlike the onn, there's even DTS support.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar has a pretty stylish design that looks good from your couch. There's a nice grey-colored fabric wrapping around the front, and it's also covering the Atmos drivers on top. However, when you look at it closely, you can see that the top part of the bar doesn't feel very premium. The plastic buttons are cheap-looking and clunky to touch.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar's sub has a simple design, so it fits discreetly into your living room without drawing a lot of attention. It's black, with a melamine build and a plastic bottom.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar is fairly wide, so it doesn't fit between the legs of a 55 inch TV stand. It's also a bit taller than other bars, but still, it shouldn't block your TV screen unless your TV sits flush on your table.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar's sub is roughly the size of a typical desktop computer. It connects to the bar wirelessly, making it easy to place anywhere in your setup. You just need to connect it to a power outlet to use it.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar has a decent build quality. It seems like the top is made of either melamine or MDF, which doesn't feel very premium, and the plastic buttons seem rather cheap. There's a nice fabric covering the Atmos channels on top, and it also covers the front of the bar. The back and the bottom of the bar are made of plastic. The subwoofer, meanwhile, is mostly made of melamine with a plastic bottom.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar has a good stereo frequency response. Right out-of-the-box, it has a dark and bass-heavy sound profile that really emphasizes the punch and thump in the bass range. Voices are still pretty clear in the mix, but there's a little extra boom that carries over into the mid-range where they're reproduced, so they also sound a bit muddy. The recessed treble range causes the dark sound, meaning that higher-pitched voices and instruments like cymbals are dull in the mix. That said, there are subwoofer level and treble adjustments on hand to help you customize its sound.
With its subwoofer level set to '-6' and its treble set to '3', the onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer has a good stereo frequency response. Its sound profile is more neutral and balanced, especially in the bass and treble ranges. Vocals are clearly and accurately reproduced thanks to its balanced mids, and you can hear higher-frequency sounds such as cymbals, too. The bass is present and thumpy, but it doesn't overwhelm the other instruments in the mix.
Note: We usually perform the calibration tests with the bass and treble adjustments. However, the onn. 42" 5.1. 2. Dolby Atmos Soundbar has a subwoofer level adjustment instead. The difference? It only adjusts the amount of bass reproduced by the subwoofer, while a bass adjustment feature would control the bass reproduction of the sub, the bar, and the satellites together. You can still get a solid result with the subwoofer level, as seen in the graph above.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar has a decent stereo soundstage. The soundstage is perceived to be a little wider than the bar itself, but it doesn't have any tricks to make it seem wider than that. On the upside, it has good focus. If you're listening to a recording of an orchestra, for example, each instrument seems to come from an accurate, pinpoint location in the soundstage, matching the spots where each musician would sit in the pit.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar has a decent stereo dynamics performance. This bar can get pretty loud, so it can easily fill a large and open living room. However, at its max volume, there's quite a bit of compression present that degrades the quality of your audio. It's better to listen to the bar at average volumes if you want a clean audio reproduction.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar has a great stereo THD performance. At an average listening volume, distortion falls within good limits, so your audio is clean and pure. Like most bars, there's a jump in THD when you push the bar to max volume, especially in the bass range. That said, this isn't an issue if you listen to the bar at moderate volume levels.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer has a great center channel performance. Its discrete center channel anchors voices to a pinpoint location in the soundstage, so dialogue is more clearly and accurately reproduced. Its neutral, balanced frequency response, especially in the mids, ensure that voices are clear and detailed, too.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer has a poor surrounds performance. It uses side-firing drivers built into the bar itself to simulate surround objects (think voices, footsteps, or moving vehicles) in the soundstage. However, these objects don't sound as clear and real as they would with a discrete localization. Audio seems like it's coming from in front of you, rather than from speakers placed all around you. There's a large dip in the treble range, too, so higher-pitched voices are quite dark and dull.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer has a disappointing Atmos performance. It uses its two up-firing drivers to bounce sound off the ceiling to create the illusion of height. Dialogue in movies is pretty clear, thanks to the balanced mids, but higher-pitched voices are dark due to the recessed treble.
As for its soundstage, the onn. 42" 5.1. 2. Dolby Atmos Soundbar does a decent job replicating height in certain movie scenes. However, sound seems to reach to the sides of the room, and it doesn't extend over your head or behind you. It doesn't seem to immerse you like more premium bars on the market. Sound is pretty quiet, too, so you need to crank up the volume to really get a solid listening experience.
There aren't a lot of sound enhancement features available, which is pretty typical for bars in this price range. You have a couple of EQ presets available, including 'Standard', 'Music', and 'Movie'. That said, these presets don't actually change the bar's frequency response as shown by the graph here. Also, unlike a lot of other budget-friendly bars, there's no dialogue enhancement mode or auto-volume feature, which is disappointing if you watch a lot of vocal-heavy content and want to control the clarity of dialogue.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer also has a subwoofer level adjustment feature that lets you control the amount of bass reproduced by the sub. The bar's display reads 'BASS' when you adjust this feature, but the manual specifies that it only controls the subwoofer, not the bar like a true bass adjustment feature would.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer has a lot of physical inputs to choose from. You can connect it to your TV using its ARC and HDMI In connections, and there's an Optical port for connecting to older TVs. The Ethernet port lets you connect the bar to the Internet, too, so you can access Wi-Fi and Apple AirPlay. The Ethernet cable is included in the box, which is handy.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar has amazing audio format support via ARC. There's support for the most common surround sound format, Dolby Digital. It can also playback some lossless and object-based formats like Dolby Atmos. Unfortunately, there's no support for DTS, which is found on some Blu-ray discs.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar has excellent audio format support via Full HDMI In. It supports Dolby Digital surround sound as well as some lossless and object-based formats like Dolby Atmos. That said, there's no support for DTS content.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar supports Dolby Digital content via Optical. It's the most common surround sound format, and you can often find it on Blu-rays and streaming platforms. There's no DTS support, but this format isn't very common on its own.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar has a fantastic latency performance. The audio you hear is in sync with the video that you see on your screen, and you don't notice any delays with lip-synching. Keep in mind that there are many factors that can influence latency results, including the TV or the app that you use, so your results can vary.
There are a few different ways to wirelessly stream audio to the onn. 42" 5.1. 2. Dolby Atmos Soundbar. You can stream from your mobile devices to the bar via Bluetooth. The bar isn't capable of Wi-Fi on its own, unfortunately, but you can use the included Ethernet cable to access Apple AirPlay. However, this feature doesn't work if the Ethernet cable isn't connected.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar can passthrough some of the highest quality bandwidth signals. When you use the bar as a hub between two devices, such as your PC and your TV, text on the screen is clear and crisp. That said, there's no Dolby Vision Passthrough support and it can't passthrough 4k @ 120 Hz, either.
There's a display on the front of the bar, beneath the fabric. It shows you the audio format that's being played as well as the settings as you change them. However, it can be hard to read the display when there are a lot of lights on in the room. Unfortunately, there's no way to change the brightness.
There's also a small red light located near the screen that shows whether or not the bar is connected to the Internet. It flashes for fifteen minutes when there's no connection, and then it turns off. If the included Ethernet cable is connected and the light is still flashing, that means that the bar needs a firmware update. It updates automatically, though.
On top of the The onn. 42" 5.1. 2. Dolby Atmos Soundbar, there are some buttons. You can use them to power the bar on/off, change the input, adjust the volume, and play and pause your audio.
The onn. 42" 5.1. 2. Dolby Atmos Soundbar with Wireless Subwoofer's remote is simple and lets you control the bar's features. That said, it's not a universal remote, so it can't be used to control your TV.
