When it comes to improving your TV's audio, soundbars have become the go-to solution for most people. Let's compare two popular options: the entry-level Samsung HW-B550D ($177.99) and the premium LG S90TR ($799.99). While both aim to enhance your listening experience, they take quite different approaches.
Before diving into the specifics, let's talk about what matters in a soundbar system. The key factors are:
The number of channels is written like "3.1" or "7.1.3" - where the first number is regular speakers, the middle is the subwoofer, and the last (if present) is height speakers that bounce sound off your ceiling for overhead effects.
The Samsung HW-B550D uses a 3.1 channel setup, which means you get three front speakers (left, center, right) and a subwoofer. This configuration excels at clear dialog and decent stereo separation for music, but it can't create true surround sound. Instead, it uses digital processing (DTS Virtual:X) to simulate surround effects.
In contrast, the LG S90TR delivers a full 7.1.3 channel experience with actual speakers all around you, plus three upward-firing drivers for height effects. This creates genuine surround sound with audio coming from all directions, including above. The difference is similar to watching a 3D movie versus looking at a really good painting of a 3D scene - both can be enjoyable, but one is more immersive.
Released in early 2024, the LG S90TR represents current state-of-the-art soundbar technology. It includes AI room calibration (which adjusts the sound to your specific room), Dolby Atmos and DTS:X support (for 3D audio), and integration features with LG TVs. The system can analyze your room's acoustics and adjust its output accordingly.
The Samsung HW-B550D, while newer than many budget soundbars, focuses on core features rather than cutting-edge tech. It still includes useful features like dialog enhancement and night mode (which reduces loud sounds while keeping dialog clear), but skips the more advanced processing.
I've tested both systems in various settings, and here's what stands out:
For standard TV watching and casual music listening in a small to medium room, the Samsung performs admirably. Dialog is clear, music has decent stereo separation, and the subwoofer adds satisfying bass for explosions and music. The virtual surround effects can create some sense of space, though you won't be fooled into thinking sounds are coming from behind you.
The LG system simply operates on a different level. In a properly set up room, it creates a bubble of sound that genuinely surrounds you. When watching movies with Dolby Atmos, you can hear helicopters move overhead or rain seemingly falling all around you. The subwoofer integrates better with the overall system, providing deeper, more controlled bass.
In smaller spaces (under 200 square feet), the Samsung's limitations become less noticeable. The virtual surround can work quite well when walls are closer, and the simpler setup might actually be beneficial where space is tight. You'll still get clear dialog and good stereo separation for music.
For larger rooms or dedicated home theater spaces, the LG's advantages become more pronounced. The extra speakers and processing power help fill the space more effectively, and the true surround sound creates a more theater-like experience. The AI room calibration becomes particularly valuable in larger spaces where room acoustics play a bigger role.
At $177.99, the Samsung HW-B550D delivers impressive value for basic TV audio enhancement. It's particularly strong for:
The LG S90TR at $799.99 represents a significant investment but justifies its price for:
Consider these questions:
Both soundbars serve their intended purposes well, but they're designed for different users. The Samsung HW-B550D provides excellent value for basic TV audio enhancement, while the LG S90TR delivers a premium home theater experience for those willing to invest in it.
If you're coming from TV speakers, either will be a massive upgrade. The Samsung gives you 80% of the way there for 20% of the price, while the LG delivers that extra 20% of performance for those who can appreciate (and afford) the difference.
My recommendation? If you're just looking to improve your TV's sound and primarily watch regular shows, save your money and get the Samsung. But if you're serious about home theater, game a lot, or really love immersive movie experiences, the LG's premium features are worth the investment.

The LG S90TR ($799.99) is significantly better for movies due to its 7.1.3 channel configuration and Dolby Atmos support. While the Samsung HW-B550D ($177.99) provides good movie audio, it lacks true surround sound and overhead effects.
The price difference is $622, with the Samsung HW-B550D at $177.99 and the LG S90TR at $799.99.
Both soundbars work with any TV with HDMI ARC. However, the LG S90TR offers additional features like WOW Orchestra when paired with LG TVs, while the Samsung HW-B550D works equally well with any brand.
The Samsung HW-B550D is more suitable for small spaces due to its compact size and 3.1 channel setup. The LG S90TR may be overkill in rooms under 200 square feet.
Yes, both the Samsung HW-B550D and LG S90TR can be wall-mounted, with mounting brackets included in the package.
The LG S90TR offers superior gaming performance with its surround sound capabilities and height channels. The Samsung HW-B550D provides decent gaming audio but lacks immersive surround effects.
Only the LG S90TR has rear speakers, and they're completely wireless, needing only power cables. The Samsung HW-B550D doesn't include rear speakers.
The LG S90TR has more powerful and refined bass with its larger subwoofer. The Samsung HW-B550D provides adequate bass for most content but isn't as deep or impactful.
