Expert Reviews


What experts liked

The LG SJ9 is the most affordable Dolby Atmos sound bar system on the market, at least in the US. Home theater sound is dynamic and thrilling. Compatibility with Google Chromecast and 4K HDR offers some degree of flexibility and future-proofing.
- CNET
Spectacularly powerful sound and LED display. It has remarkably compact design and chromecast support built in.
It’s an immensely powerful soundbar, attacking effects with gusto and generating a huge Atmos soundstage that reaches high and wide. The sound is anchored by deep and well-integrated bass from the wireless sub and peppered with crisp high-frequency detail. That all adds up to a wildly entertaining sound, which knocks the slimmer SJ8 into the proverbial cocked hat. It’s attractively styled and packed with features, allowing you to stream music from a wide range of sources.
Includes CTA certification to play high-resolution audio at the proper quality level with 24-bit upsampling. Offers Chromecast built-in streaming option. 500 watts of power. Includes support for audio found in 4K video with HDCP 2.2 compatibility. Has both WiFi and Bluetooth connectivity options for streaming music.

What experts didn't like

The LG SJ9’s subwoofer makes a lot of bass, but definition is only so-so. The sound isn't very refined when playing music. The 'bar lacks DTS:X or DTS-HD Master Audio compatibility. No surround speakers included.
- CNET
Only one HDMI input and HDMI handshake issues. Limited rear/overhead channel effects.
I experienced problems streaming from my NAS drive, and the inclusion of a single HDMI input is a tad stingy for an expensive flagship soundbar. DTS:X support would also have been nice. Otherwise, the superb SJ9 is a great advert for Dolby Atmos and a terrific introduction to the delights of 3D audio.
Extremely high price tag versus other types of soundbars. Complex setup.

Overview

Now that you can order a film at the press of a button, movie night has moved from the cineplex to living rooms. For that reason, it’s likely no surprise that consumers report they’d rather watch a movie at home than leave the house. But getting the same experience at home as you do in a theater can be challenging.

Even if you take advantage of the low prices on high-quality big-screen TVs, duplicating true movie theater surround sound can get expensive. In recent years, soundbars have advanced to the point where they now can simulate surround sound for a fraction of the cost of a speaker set. But one soundbar can differ dramatically from another, so it’s important to do your research before you buy.

Soundbars can range in price, but you’re sure to find one that fits within your budget. When shopping for soundbars, pay close attention to the range of tones you’ll get. Some soundbars can’t handle bass as well as others, even when they’re promising the best sound quality.

Once you get your soundbar home, you’ll generally be on your own to make it work with your existing systems. One of the best things you can do is take note of the equipment you already have and make sure the soundbar you choose is compatible. Many of today’s speakers use Bluetooth connectivity to allow you to eliminate unsightly wires. So if you have an older TV or receiver, you may find the soundbar you’ve bought won’t connect.

Finally, stop to think about where you’ll set up your new soundbar, as well as any speakers you plan to add on to it. There are soundbars you can mount on the wall, while there are many others that can be set on your furniture in front of your TV. Whichever option you choose, note the dimensions of your soundbar in advance to ensure you know how much room it will take up.

Buying Advice

  • If your soundbar doesn’t sound good, there’s no point in even having one. If you’re going for the best sound, consider the Bose Solo 5 TV Soundbar & Universal Remote Control. It has great sound and great ranges. The Bose Solo also performs better in the deeper ranges, with bass you can feel in your chest.
  • For those interested in building a true home theater, adding on extra speakers is the key to success. Some models allow you to easily buy extra speakers to connect to your soundbar.
  • Setup can be intimidating if you don’t consider yourself a tech guru. Some models can be tricky to set up, especially when it comes to pairing with other equipment.
  • One of the biggest concerns when shopping for any speaker is where it will be. Some models are designed to hang on a wall, but they can also rest in front of your TV. Others can be mounted, but they look great in front of your TV. If you’re limited on space, you may want to avoid any soundbar that comes with a separate subwoofer that you’ll need to place.
  • If you’re looking for the smallest soundbar, the SAMSUNG HW-T450 Dolby Audio Soundbar is the shortest, at only 2.1 inches tall.
  • One size benefit to smaller models is that they can be easily mounted horizontally or vertically, with the sensor automatically adjusting the sound depending on how you’ve oriented it.
  • If you have an Amazon product that uses Alexa, look for a unit that you can connect to your device, so that you can play music on command.
  • With some soundbars, you’ll have access to an app that you can then use to control your speakers. However, they may not come with a remote control, which means you’ll need a universal remote if you can’t connect it to an existing smart remote. Some soundbars come with a remote, but they’re still a bit bulky. You’ll also need to have two AAA batteries on hand for the models that use batteries.
  • Look for a soundbar that is built to last with durable ABS plastic beneath the soft cloth cover. Be aware that some models can scratch easily.
  • When it comes to price, you’re going to pay much more for some soundbars than other speakers. Be sure to consider whether you’ll also need to pay for separate speakers. In some instances, the price may also include a subwoofer, so keep that in mind.
