    I am not an audiophile-in fact I had convinced myself that sound quality did not matter if you were watching TV. I was wrong! This soundbar and subwoofer were packaged well. Never having wireless anything before (other than my tablet and computer) I was a little surprised and worried about the ‘extras’ in the box. I had not reason to be concerned. The installation and setup were well explained in the instructions and were very easy. I am totally blown away by the ease of use, the intuitiveness of use and the sound quality. We have an LG TV and the integration with it was seamless. The sound bar is unobtrusive, but the sound is clear, crisp. The wireless subwoofer really packs a punch. The remote is easy to use. We watch everything with the sound system on now – from game shows to the news to moveis and sports. It really makes a difference and we are truly enjoying out viewing-listening experience! “I received this product at a discounted price in exchange for my honest review”

    Sound this good used to mean a whole day of tinkering setup frustrations. Now, with HDMI-CEC and ARC technologies, you can be up and running in minutes!
    This soundbar turns on and off along with my game console, television, and streaming box. With AI Sound Pro, my content always sounds it’s best.
    The default 3.1 configuration sounds so good, I may have to pickup the optional rear surround kit to make this a 5.1 system!
    Helpful tips to help you maximize your setup out of the box:
    Enable HDMI CEC on all connected devices (sometimes called Simplink or by other trade names, or more generically as HDMI control, this technology controls sleep/wake and auto-negotiates input, passes remote commands such as volume and mute, and is the secret sauce that lets it all work seamlessly!)
    Make sure your devices can output bitstream audio for highest quality, or at least PCM
    Connect the HDMI Out on this soundbar to the HDMI ARC port on your television (this allows for the best sound quality with this system, and allows all HDMI devices connected to your TV to use your TV as an audio selector switch)
    And that’s basically it! Plug in the sound bar to power, then the sub, and you’re ready to rock!!!

    Some major points. Sounds great. Bass isn’t annoying. Does come with mounts. You just need anchors and screws to center it under the TV. It comes with small screws to attach the bar to the mount tho. Don’t lose those. Its comes with a perfect paper template to make your holes. Make sure the paper is perfectly flat to the wall before drilling. Drill right through the paper. Also it DOES Bluetooth music. It does not have Alexa or Google. Or voice control. But for $250 this thing is awesome. Set up is very easy. Plug in the hdmi to your ARC hdmi outlet on your TV. And plug in power cord. The subwoofer is just a power cord. It has a pairing button but should just automatically connect. Enjoy

    This is a great soundbar to pair with any LG television. I have mine paired with my 75 Nano 90, and the sound is amazing. You’re not going to throw a concert with this but it would definitely fill a large room with very clear sound. I have mine paired with the LG SPK8-S surround sound speakers, which creates amazing 5.1 immersive experience. I would say this is definitely worth the money. Although you can get much better Sound Bars at much higher prices, I think this will do just about everything you need. Oh, I didn’t mention the base. The wireless subwoofer gives off very clear and precise Bass which totally enhances the audio experience. Overall the system it’s constructed well with quality materials. Not much plastic at all. And includes mounts with mounting template which makes it very easy to wall mount. Connection options include HDMI ARC, Optical, and Bluetooth. You could also use LG Smart sync. I definitely recommend this unit to someone who wants a nice big Soundbar with great sound add at a moderate price.

    Awesome sound bar system. Was going to buy the one step below and was told to get this one and did not regret it. Would highly recommend getting it if you have an LG tv.

    The subwoofer was going in and out but my bf just figured it was an interference issue because it was next to the wifi box and too close to the sound bar. We put it in the floor and it hasn’t messed up since. But it’s not aesthetically pleasing to me. I rather it sit on top of my entertainment center with no issues.
