Adding a soundbar is one of the easiest ways to enhance the overall sound quality of a TV. However, buying a soundbar for a TV can quickly get confusing, especially when you are presented with 2.1, 5.1 and Dolby Atmos soundbars as options. The question remains, which one of these actually makes the biggest difference and is it worth paying more for?
I compared these three popular soundbar configurations to understand what you really get for your money. Let me break it down for you. But before that, here's a quick comparison for your reference.
2.1 channel vs 5.1 channel vs Dolby Atmos soundbars: What's different?
FEATURE | 2.1 CHANNEL SOUNDBAR | 5.1 CHANNEL SOUNDBAR | DOLBY ATMOS SOUNDBAR |
| Channel configuration | 2 main channels + 1 subwoofer | 5 main channels + 1 subwoofer | Varies, e.g. 3.1.2, 5.1.2 or 5.1.4 |
| Speaker setup | Left + right + subwoofer | Left + centre + right + surround speakers + subwoofer | Main, surround, subwoofer and often dedicated height/up-firing channels |
| Surround sound | stereo or virtual surround | More convincing surround sound | Most immersive, especially with physical height channels |
| Height effects | Usually no | Usually no | Yes, when equipped with height/up-firing speakers |
| Bass | Good, particularly with a dedicated subwoofer | Stronger cinematic presentation with subwoofer | Depends on configuration and subwoofer |
| Dialogue clarity | Good | Usually better due to dedicated centre channel | Generally excellent on models with a centre channel |
| Movie experience | Good for casual viewing | Better for home theatre | Best for compatible Atmos movies and shows |
| Gaming | Suitable for casual gaming | Better positional audio | Best suited to immersive gaming with Atmos support |
| Room size | Small to medium rooms | Medium to large rooms | Medium to large rooms, depending on configuration |
| Installation | Easiest | More involved because of rear speakers | Varies; more advanced setups can require additional speakers |
| Cable management | Minimal | More cables, especially with wired rear speakers | Depends on whether rear/height speakers are wired or wireless |
| Best for | TV shows, music and everyday viewing | Movies, sports and home theatre | Cinematic movies, gaming and immersive audio |
| Price | Generally most affordable | Mid-range to premium | Usually more expensive, especially with physical height channels |
What is a 2.1-channel soundbar?
A 2.1-channel soundbar typically pairs a left and right channel with a dedicated subwoofer, which makes it a simple option for better TV sound and punchier bass. These left and right speakers give users a stereo sound experience. However, they fail to deliver a more wholistic surround sound experience. The benefit of using a 2.1-channel soundbar is that it takes very little space and is easier to setup. It also costs a lot less than other setups. As mentioned before, This setup doesn't provide any real surround sound as it lacks rear speakers. That said, such a set is ideal for small to medium-sized rooms.
What is a 5.1-channel soundbar?
A 5.1-channel system, on the other hand, adds dedicated surround channels, which creates a wider and more immersive experience, especially for movies and gaming. It uses five separate audio channels and one subwoofer channel for deep bass. This setup splits sounds across multiple directions to make movies and games feel more immersive. Needless to say that a 5.1-channel soundbar creates a surround sound experience. Such a setup also provides a deeper bass. However, it is more expensive than a 2.1-channel system. In addition to this, there is also the added hassle of wires running across the room or dealing with separate power connections for wireless rear speakers. Apart from this, 5.1-channel soundbars rely on wall reflections to mimic rear speakers, which fails in open-concept or irregular rooms.
What is a Dolby Atmos soundbar?
Then there are Dolby Atmos soundbars use additional speakers, including upward-firing drivers or virtual processing to create a more three-dimensional soundstage. These soundbars include an all-in-one or modular speaker system that processes object-based audio, which in turn projects sound not only horizontally around you, but also vertically. This, in turn, makes audio effects like rain or helicopters sound like they are coming from directly overhead. The benefit of having a Dolby Atmos soundbar is that it provides an immersive 3D sound experience along with space saving design and compatibility with modern spatial audio mixes. However, Dolby Atmos speakers are space dependent and they also are pricier than regular soundbars.

The Research
I’ve used and tested hundreds of soundbars across price points and types. I’ve also been writing about consumer electronic devices and home appliances for over a decade.
To compile this guide, I’ve used at least a dozen soundbars with various channel configurations and combed through Reddit pages that talk about their audio technology, drivers, and factors that impact their overall performance. Like all HT journalists, I review products with complete editorial independence and recommend products based on my learnings.
