What people are saying

Rated 1 out of 5 by from Subwoofer won't connect After 30 months sub woofer won't connect. Product support has been unresponsive. There are no local authorized repair shops. LG won't give me a parts list so I can't replace the circuit boards myself. Purchased with 77" OLED TV. Very disappointed. Sorry I recommended the same one to a friend who has same issue.

Rated 1 out of 5 by from Stopped Working After 1 Year We originally lived this SoundBar and Subwoofer combo; however, it stopped working after a year. I tried to seek help and was told there is nothing the my can do since it has been a year. After mor research this is clearly a bug with the PCB board and LG really should fix this for customers at no charge. Very disappointed as we spent a lot of money on this and chose LG thinking we were in good hands.

Rated 1 out of 5 by from Don't Buy LG SN9YG with SPN8-W Subwoofer stopped working after 1 yr!!!!!!!!! After researching Mega Reviews and Complaints this is a HUGE ISSUE related to firmware and LG is Not doing anything about it. This should be a Class Action Suit. Don't Waste Your Money on this. Pay attention to reviews over 1 year old.

Why is google assistant not working any longer?

Asked by: George Garber
Hi, George Garber! Thanks for the question! It is still working. Try to double check your connection. The Google Assistant only responds to voice commands when you are using Wi-Fi or BT (Bluetooth) as the input. The Google Assistant may be slow to recognize or act depending on the Wi-Fi connection status or Google server status. If it still does not work, you may send us a private message on Facebook or Twitter using @LGUSSupport, and include your contact info, or reach us at our customer service line at (800) 243-0000, and we will be happy to assist you further. Thank you. ^Jolly

Is it possible to use the subwoofer on its side inside a small open cupboard? Would this effect the sound performance and more importantly damage the Subwoofer over time?

Asked by: alexitalia
The Subwoofer for the LG SN9YG 5.1.2 Channel High Res Audio Sound Bar with Dolby Atmos® and Google Assistant Built-In or for any Soundbar is Omnidirectional so it does not matter if you stand it upright or place it on its side. It will not be damaged over time by placing it on its side...^Ivan

I am considering the SN9YG soundbar to pair with my existing C9 65 inch TV. Will this soundbar sit comfortably in front of the TV on the tabletop. Will the height have sufficient clearance so that the image is not blocked by the soundbar?

I'm trying to confirm the difference between the SN9YG and the SN8YG. Does the SN9YG actually come with 2 remote surround speakers? (not shown in any of the pictures) or are these built into the bar?

Asked by: C9owner
No. You have to purchase them separate. Only the SN11YG includes rear surround speakers.

I see that there is now the ability to add this item to the cart and order it (this was not available earlier this week). Does that mean it's been released and will now be shipping out if ordered?

Asked by: zoundsgrate
When the 'Add to Cart' is not visible on a product page for a unit that can be ordered through our site, or if the 'Where to Add' is unclickable, it means that the product is not in stock. The LG SN9YG 5.1.2 Channel High Res Audio Sound Bar with Dolby Atmos® and Google Assistant Built-In is a new 2020 product and may not have been in stock yet at the time you looked earlier this week, so now that it is on the product page for the Soundbar, it means that you can add it to your cart. Please take note that due to current circumstances, delivery times may be longer than normal. Please track your order for expected delivery date. LG usually ships most orders within 2 business days, and most orders should be delivered within 7-10 business days. Final delivery timeline depends on the delivery address, and for products that are eligible for in-home or white-glove delivery, how soon delivery can be scheduled. LG sends an automated order confirmation email within minutes of an order being placed. Please check your spam and junk folders for emails from, and add the address to your safe list or address book to ensure prompt delivery of future emails to your inbox...^IFV
