LG is making waves with its new SN6Y Sound Bar, which is replacing the LG SL6Y soundbar. With this state-of-the-art sound bar, LG is pushing boundaries and revolutionizing the way people enjoy their favorite music, movies, and TV shows but lacks the deep rumble. The LG SN6Y 420 Watt sound bar comes with a center channel for clearer dialogue and also has sound customization features (many other 3.1 soundbars lack), and delivers a fairly bass-heavy sound. The SN6Y by LG company is a superb center channel performance soundbar that has a 3.1 channel soundbar setup, and on the upside, it gets loud. But what you don’t like in this soundbar is lackness of Dolby Atmos support.

To convert LG SN6Y SoundBar from a 3.1 channel to a 5.1 setup, you must purchase a rear speaker kit for transformation. If we compare LG SN6Y with LG SL6Y, then we come to know that the back has a different connectivity design (ports and pairing button).

The LG SN6Y comes in a beautiful design with black color and a well-rounded soundbar shape, which feels much more premium where the body is made of good quality plastic, and the metal grill covers the soundbar front and protects the speaker from dust.

You will find the LG logo printed in white, which you will find in the right-hand corner and gives (for a faux-leather look). Overall in design, the soundbar is fairly wide and is 2.2 x 41.7 x 3.4 inches, and on the side, you will find a silicone pad for making the soundbar on or off / changing inputs/volume adjustment, etc. The LG SN6Y has a remote that is small and gives users playback control which is a great thing.

Team Wooster audio notices that the LG SN6Y features the same input options as LG SL6Y, but SN6Y lacks a 3.5mm aux port availability and does not support Chromecast or Apple AirPlay, so that is a strange thing for any audiophile who needs these features.

Some Connectivities Of LG SN6Y Soundbar

  • HDMI input (for gaming console)
  • HDMI ARC port
  • Optical cable (for tv connection)
  • Bluetooth Connectivity

If we compare LG SN6Y with the Samsung HW-R650 soundbar, then we found a difference between balance as the Lg soundbar is not as well-balanced as the Samsung ones and doesn’t support Atmos like the Sony HT-Z9F. But in price, the LG SN6Y soundbar wins the game and is more budget-friendly, and you will get immersive quality sound.

Let’s take a look at LG SN6Y soundbar subwoofers which is a wireless subwoofer design that deviates slightly and has a front covered in the fabric where the top is coated in plastic, and you will find a logo that is shifted to the top too.

So overall, the LG SN6Y soundbar is the best soundbar for the Lg Oled cx smart tv and has great features of audio decoding codecs like DTS Digital Surround, DTS Virtual:X, and Dolby Digital, and both soundbar and subwoofer will provide you with heavy quality sound which makes your movie enjoyment more enjoyable.

The Jbl Bar 9.1 soundbar is a perfect choice for pairing with the LG OLED CX Smart TV in terms of design. The Jbl Bar 9.1 soundbar has a modern and sleek design with a matte black finish and metallic accents, which complements the LG CX Smart TV’s slim and elegant profile—and giving it a premium look that matches the premium features of the LG Tv.

It provides a realistic 3D audio experience and precise sound placement with its 9.1 channel configuration and Dolby Atmos and DTS:X technology. It also has multiple sound modes, including music, movie, and sports which can optimise the sound quality for different types of content. 

The JBL Bar, 9.1 soundbars, is a premium audio product with a higher price point than other soundbars in the market, which may not be suitable for those on a low budget. But if you are looking for a high-quality audio experience and are willing to invest in a premium product, the JBL Bar 9.1 can be worthwhile. And if you are looking for a more budget-friendly option, JBL offers a range of other soundbars like JBL Bar 2.1 or JBL Bar 5.1.

Polk Audio Signa S2 Ultra-Slim TV Sound Bar (Image credit: Amazon)

Polk Audio Signa S2 Ultra-Slim TV Sound Bar

Polk Audio's flagship soundbar


  • Channels: 2.1
  • Surround Format: Dolby Digital
  • Bluetooth: Yes


+ Control panel up top

+ Universal tv soundbar

+ In-expensive soundbar

+ Removable front grill

+ Ultra-slim design

+ Can place easily

+ 5 full-range drivers

+ Voice Adjust Technology

+ Reasonable price

+ Flexible placement

+ 2.1 channel system

The Signa S2 is a flagship sound bar by Polk Audio that provides performance-tuned surround sound, which is suitable for tv shows you are watching on Lg Oled cx tv. The Signa S2 has a V-shaped sound signature (not best balanced) and does not have a dedicated center channel compared to LG SN6Y, but still, you will get quality sound. The center channel is excellent for sound quality, whereas Polks audio Signa S2 lacks it and has the same budget as LG SN6Y, so we will recommend you purchase an LG soundbar instead of a Polk audio soundbar in this situation if you need a center channel.

The Polk Audio Signa S2 features a Premium ultra-slim soundbar design so that its slim size fits more spaces or fits into any home theater or living room, and it offers powerful sound output that will fill any room with rich, immersive sound and also Dolby digital surround sound is available.

The  Polk Audio Signa S2 is 3.31 inches deep,2.15 inches tall, and 35.43 Inches wide (Low profile design), so that you can easily wall mount it and set it. The overall sound quality you will get in great waves, but if you push Signa S2 soundbar sound limits, then the result you may hear is compression and distortion (A loud enough sound) where you don’t have to do that, in my opinion, you can use its dialogue enhancement feature to get great clarity (Polk Adjust Technology for voice levels).

If you purchase a set of Polk Audio Signa S2, then you will get a Wireless subwoofer which is an exclusive subwoofer that provides powerful deep bass, which will take your home theater listening experience to a whole new level. The Front array subwoofer driver is 5.25 inches (13.34 cm ) d round.

The Signa S2 soundbar is powered by Polk’s award-winning technology and features universal capability, and easily works with 4k and HD TVs. So, in summary, the Polk audio Signa S2 is more budget-friendly and under the price; not only will you get clarity sound with Dolby Digital decoding, but also you get convenient connectivity options like HDMI, optical cable, and Built-in Bluetooth technology for wireless connectivity so you can connect this Polk audio soundbar with your Samsung 56 Inch or Lg Oled cx tv without any worries.

Professionally Designed Soundbar

- Lacks a bit of bass

- HW-Q70T Soundbar downmixing surround content to stereo

- Poor surround performance

- Lacks sub-bass

The Samsung HW-Q70T 3.1.2ch soundbar is quite impressive! It’s a great addition to my home theater setup and perfect soundbar for QLED TV and 55-inch TVs which will provide you neutral, well-balanced sound.

The Samsung HW-Q70T also comes with a number of features that make it an all-around great option. The HW-Q70T soundbar is similar to the 2019 Samsung HW-Q70R soundbar but in sound quality it wins where the coming rear speakers are not as excellent as the Samsung HW-Q90R soundbar. Also there is remote central unit available for more visibility.

The Samsung’s 2020 lineup HW-Q70T 3.1.2 setup soundbar features a number of useful remote control features including voice search, pause/play media, and more. The HW-Q70T comes with Dolby Atmos and DTS:X. Dual technology and supports Atmos content which in results deliver robust 3D surround sound.

The HW-Q70T soundbar by samsung is using  two up-firing speakers on the bar and has well-built soundbar design and also you will find 4-character display small screen behind grill (shows volume and input level) which is unique feature you will not find in LG SN6Y, Polk Audio Signa S2 and LG SL5Y soundbars. You will find HW-Q70T Controls located on the panel’s top.

  • Power button
  • Volume rocker
  • Input selection buttons 

So overall, the HW-Q70T soundbar is a great opinion but there are some demerits like panel brackets cannot fit on the wall. So in budget you are also getting soundbar with subwoofer and a great samsung soundbar so if you need more than samsung just announced 2023 soundbar lineup which includes Q990C, S800B, and G60C samsung soundbar with fully latest Q-Symphony features.

How To Buy Best Soundbar For Lg Oled Cx

The LG OLED cx soundbar is an excellent quality smart tv, and selecting the great soundbar will be the first priority to get excellent music quality out of the soundbar from LG CX smart tv. Finding the best soundbar for LG oled Cx will require some process to get great one and some considerations you have to consider before you are going to purchase a new one.


Before purchasing a new soundbar for an Lg tv, ensure the space around your tv so that space will decide the soundbar type whether you need a soundbar or soundbase. For installation, the soundbar is excellent and versatile, and you can wall hang and can sit them on the LG tv front side. 

If your LG tv is put on a table or credenza, then below the LG tv screen, you can put the soundbar easily on the same table, whereas if you have wall mounted your LG Tv, then you can wall mount your soundbar.

Different Soundbar Sound Waves On Top Of Table Or Wall Mounted

So overall, always ensure soundbar mounting before you purchase! We have made a diagram of soundbar sound waves for both wall mounts and putting on any credenza or media cabinet.

Soundbar Size

The size of the soundbar is a simple recommendation as each soundbar comes in the exact width and can easily pair with any smart tv size. For example, having a 55 to 65-inch LG smart tv will require a 50 inches long soundbar.

Active And Passive Soundbar

There are two types of soundbars:

  • Active Soundbar
  • Passive Soundbar

If you go with Active soundbar, then you will get built-in amplifiers (for power everything), channel processors ( for right and left center speakers), and a great benefit is no plug to extra receiver required to purchase and if we talk about wires then always remember active speakers require fewer wires.

If we talk about Passive soundbars, then as compared to active soundbars, in passive soundbars you will not get a built-in power amplifier, so you have to purchase a separate receiver amplifier, and little costly but provide sound quality better than active ones due to having better speakers installed. Just passive speakers require more components to connect, so if you need a plug-and-play soundbar on a normal budget, then go with active soundbars.

Soundbar Channel

Before you select the soundbar for your Lg oled cx smart tv, you have to select channels as sound sources and also for individual speakers. As technology increases, so shows and movies come with more surround sounds and offer five different audio channels.
