General Specifications
About the Product
Bring the high-end cinema experience home. The SJ9 starts with Dolby Atmos three-dimensional surround, then adds CTA-certified high-resolution music playback with 24-bit upsampling plus the convenience of Chromecast built-in streaming. Ultra HD video is supported as well, via 4K pass-through.
Dolby Atmos takes you there with realistic audio that flows around you. Untethered to channels, sounds exist as individual entities, positioned in three-dimensional space at precise points-even from above. So you're always at the center of it all.

LG SJ9 5.1.2 Channel High Resolution Audio Sound Bar with Dolby Atmos (2017 Model)
  • Easy set-up and good size.

What customers say about "Features"
LG SJ9 5.1.2 Channel High Resolution Audio Sound Bar with Dolby Atmos (2017 Model)
  • Excellent sound, easy to install. Makes movie night so much better.
  • We ended up having this installed in our family room. Perfect for Movie night and gaming for the kids.
  • Great sound without going to extremes in price range. It enhances TV sound much better than TV's speakers.
  • If you need a clean and compact system this is the one.
  • The Dolby atmos is seriously unreal. I enjoy this system more than any other sound system I've owned before.
Samsung HW-K950 5.1.4 Channel Soundbar with Dolby Atmos Technology (2016 Model)
  • Installation was very easy and love the rear wireless speakers.
  • So easy to install, pair automatically. Best soundbar I heard.
  • This is the perfect solution for someone like us who rent their home and can't install a permanent surround sound system in the walls.
  • I am enjoying this sound system. It enhances my viewing experience.
  • One of the best sound bars I have heard. If you are playing dolby atmos material it is top notch.
  • Soft rear speaker sound - This is a HUGE fail! If you are planning on having the speakers further than 2 feet away from the listeners head, then forget about hearing much.

What customers say about "Connectivity"
LG SJ9 5.1.2 Channel High Resolution Audio Sound Bar with Dolby Atmos (2017 Model)
  • Having the Bluetooth option is an added bonus.
  • The addition of Bluetooth for connectivity is great for streaming music.
  • I have enjoyed the wifi feature so that it links to google home for music applications in addition to just watching movies. This is one of my favorite purchases this year.
  • Sounds good if u book it up with cable but if u use the Bluetooth doesn't sound very good.
  • Overall very good product but I had issues getting it connect to my WiFi. Android apps downloaded from the store were not able to complete the Wifi setup after 4h of trying by following manual's instructions.
Samsung HW-K950 5.1.4 Channel Soundbar with Dolby Atmos Technology (2016 Model)
  • Playing songs with Bluetooth or cds, outstanding!
  • Would like a wider sweet spot. Bluetooth and Wifi from iPhone/ipad works great.
  • Everything works great Bluetooth is hard to set up wish there was a plug in to add a tuner or music.
  • This product is good but needs some possible firmware updates for Bluetooth connection with satellite speakers.
  • My guess is the bluetooth antenna in the main unit is too small.
