Purchased the sound bar a few weeks ago and couldn't be happier. I was truly amazed at the full rich theatre sound coming from it. Installation was super easy and it also looks very stylish. I couldn't be happier!

Excellent Sound Quality
Excellent immersive sound quality. Crystal clear sound and perfect Bass. Bought this a week ago and I'm already happy with this purchase. I did compare multiple soundbars from all leading brands. Decided to go with this LG sound bar.Brushed metal looks and better build quality. Supports Dolby Atmos and DTS-X which is plus. Setting up the LGSL9Y was easy, but Google Assistant setup took sometime to troubleshoot and it works. Performance is much better when the bar is set horizontally on the TV stand compared to mounting it. Adding Wireless surround sound kit would be great for watching movies.
I would definitely recommend this sound bar to anyone looking for a sleek design and great sound quality.

Excellent sound!
I received this product at a discounted price in exchange for my honest opinion. Now opinion is that the surrond sound system is amazing! Crisp sound and we even went out and bought the wireless rear speakers. This made the quality much better! But even with out the extra speaker that we purchased the sound system works amazing! The Dolby Atmos is great lets you feel like your surrounded by the action in the movie. Gives off a great movie theater sound. The Chromecast and Google Assistant are great tools and the setup was so easy that i was able to conect on my own. I am also able to connect my phone and control the sound bar so when i misplace my remote i can still control the system. All I had to do was turn on Bluetooth to my phone and it connected that easy.

Awesome Soundbar
This soundbar looks great on my mantle and provides excellent sound. The slim design fits and matches nicely with my TV. The different sound options allow me to customize how I hear movies, music, and games. The sub-woofer provides great bass and really helps movies come to life.

Hear it all!
I received the LG SL9YG Sound Bar at a discounted price for my honest review. I am so happy I got this Sound bar! It is amazing!! I can hear all the sounds so clear, even the twigs breaking when they step on them in the shows. On one show there was thunder in the background and my husband asked if it was starting to storm outside! It makes all our shows and movies sound great without a bunch of wires or speakers all over our room.

There is Bluetooth and Wi-Fi capability to hook up to your phone and the subwoofer. We used the optical cord to hook ours up and it went quickly. Hanging it on our wall was simple too!

This product is top notch in sound quality and easy to use.

A step in the right direction?
I have had the LG SL9Y for almost two weeks and it’s an enormous improvement over last year’s SK9Y. I went out and bought the wireless speakers SPK8 to pair with the soundbar for a second time. The set up was the same as last year’s model. Just make sure you are using a HDMI 2.0 cable and ARC to connect the sound bar to the TV you are using. Also, make sure if you have last years model to make sure it is off so that it pairs with the wireless sub-woofer correctly and the wireless rear speakers as well. The sound bar can be wall mounted in two positions, but I recommend placing it on an TV stand or table of choice because of the Atmos channel height requirements. Set up was a breeze after the installation of the Google home app and software update. The Soundbar does support Google assistant and the controller has a dedicated button to activate it. Google assistant works just as it works on your phone and you can request it to play from Spotify, Google play music, Pandora to list a few or even ask how the weather is today. This is a great inclusion in this year’s sound bar that I enjoy the best. The sound bar also supports DTX compared to last years model and I’m glad it is included. The sound is crisp and excellent when on Atmos paired with the rear speakers while watching Captain Marvel for a fifth time while testing. You don’t really notice the missing center channel that the SL10Y and SK9Y have, but I think this is because of the Meridian technology and I’m very impressed. This is really a step in the right direction but not including an Ethernet port and E-ARC which their new TV’s support is the only downside of this year’s model. I am hopeful that LG can release a firmware update to support E-ARC like other manufacturers have in the last couple months. I would recommend this soundbar if you are not looking for Ethernet support and E-ARC but if you are looking for these items then I suggest looking at the competition before buying this year’s LG soundbar lineup. Also, I received this product at a discounted price in exchange for my honest opinion.

Upgrade your sound
I typically hook a full 5/1 or 7/2 sound system to all of my tv's. I was excited to see what this new bar could do. The packaging was very good. Everything arrived in great shape. Hookup was easy enough. I went with both optical and hdmi connections. Single wires. No issues to report. Wi FI was easy to connect . again no issues to report. I did think that the wall installation was very easy. The paper cutout was a big help, and I was able to get the unit hung correctly and level on the first shot. Looks great and saves a bunch of space. My room looks huge without all of the full sized equipment I removed.

My initial feeling on the sound is that it is rich, detailed, and if wanted loud. I am still looking at the Bluetooth hookup, and I have to figure out how to adjust the sync features.

The sub is loud, but tight and not "boomy" . Is that a word? The remote is basic, and has the features needed, but the sound is easy to control with my LG tv remote. I will report back on the different sound filters, as I have not had enough time to play with them yet.

7-26-2019: I was right, I love it. Changed from the wall hanger to a shelf in front of tv. Love the sound. Loud and crisp. I did buy the rear wireless speaker kit. Huge upgrade. Movies sound almost as good as my old Denon and klipsh system, but no huge footprint! Sub is loud, but not muddy. I even get a nice soundstage feel for music. Buy this one!

Totally Fills My Apartment with Sound
Having just set up the LG SL9Y in my apartment and running it through various audio such as movies, TV, video games, and streaming music, I can honestly say this is the best sounding sound bar I have ever heard.

The way it fills the room makes it seem like the sound is coming from more than just the bar itself, and it has a wonderful full and rich sound.

It also looks great, and fits in front of my 65" TV perfectly, which brings a wonderful ascetic to my setup.

My only real complaint is with the setup. The directions were a bit limited, and I couldn't get it to connect to WIFI when running the app. This is needed to setup the Google Assistant and allows you to connect through blue tooth. It kept searching, but wouldn't pair, and eventually gave me a website to go to for more help, but the website didn't provide any additional information. After many tries of unplugging it and plugging it back in, I eventually uninstalled the Google Home app, restarted my phone, and reinstalled the app and it connected on the first try.

Once it was connected, the sub automatically connected and I was on my way.

I would definitely recommend this sound bar to anyone that is looking for a sleek design and great sound for their media!
