Compared with other models of the same manufacturer, it’s evident that SN4A is only suitable for a decent upgrade, and that too in case you can find it in some physical or online electronic store. However, if you have the budget and want to upgrade your home theater with a better soundbar, you may choose from the one mentioned above.

Is the LG SN4A Soundbar Worth it?

Choosing a soundbar depends on various factors, including usability, audio preferences, connectivity options, design, build, and price. So, even if one soundbar works for someone, it may not suit you. 

The SN4A soundbar is a decent upgrade for your existing TV speakers and comes with diverse connectivity options, including HDMI, ARC, Digital Optical, and Bluetooth. It also supports high-end audio formats, like Dolby Digital and DTS Digital Surround, and has powerful audio that fills the room.

Its wireless subwoofer enhances audio response and delivers robust bass without issues. As the company discontinues the model, it could be hard to find one. So, it could be a worthy purchase if you can find one.

 However, it’s advisable to consider other LG models like SPM2 and SPD7Y, that offer similar pricing, have better features, audio quality, and support audio formats like Dolby Atmos, DTS:X, and Dolby Digital Plus for an immersive listening experience.
