Soundbars for Beginners

In depth

Choosing your first soundbar can feel a little bewildering. There's a lot of technical language thrown around – “Dolby Atmos,” “eARC,” “impedance” – that doesn’t immediately translate into how the sound will actually be. Let’s break down what really matters when you’re starting out, focusing on the things that will make the biggest difference to your listening experience without getting bogged down in overly complicated features. Essentially, it comes down to channels, power and connection types.

The concept of ‘channels’ is key. A traditional surround sound system uses multiple speakers positioned around a room – front left, center, front right, rear left, rear right, and often a subwoofer for the bass. A soundbar aims to mimic this effect, but it does so with a single unit. Most soundbars are marketed as having “5.1” channels, which is meant to represent that surround experience. However, don’t be immediately misled. The "5" refers to five speakers – usually two on the sides and one firing upwards for simulated height effects (more on those later). The ".1" indicates a dedicated subwoofer, providing the low-frequency rumble of things like explosions or basslines. Some soundbars don't include a separate subwoofer; instead, they rely on a ‘ported’ design where the cabinet itself is shaped to amplify certain frequencies. This can work well in smaller rooms, but generally a proper subwoofer will offer more power and a deeper, cleaner low-end response. It’s worth considering if you’ll be primarily listening to music or watching movies – music often benefits hugely from a dedicated sub.

Next up is power - measured in Watts per channel (WPC). This indicates how loud the soundbar can get before distorting. A higher WPC rating generally means more powerful output, particularly at lower frequencies. Don’t get hung up on incredibly high numbers; most decent entry-level and mid-range soundbars offer between 30W and 80W per channel. For a standard living room size (around 15-20 square metres), 60W per channel would be more than sufficient for most movies and TV shows. Again, what sounds ‘loud’ is subjective – it's about the clarity of sound at different volumes, not necessarily just sheer volume levels. It's also worth noting that a powerful soundbar won't necessarily translate to better quality; accurate reproduction is far more important than simply being loud.

Connection types are where things can get particularly confusing. HDMI eARC (enhanced Audio Return Channel) is increasingly becoming the standard for connecting your TV to a soundbar, especially if you have a 4K television. eARC allows the soundbar to receive high-quality audio signals directly from your TV without needing a separate optical cable. This is almost essential if you're planning on watching HDR (High Dynamic Range) content – it’s how the best audio formats like Dolby Atmos are transmitted. However, older TVs may only have HDMI ARC (Audio Return Channel), which is a simpler but less effective connection. Other connections include Optical Digital Audio and 3.5mm AUX jacks - these are often used for connecting devices like laptops or smartphones. Pay attention to whether the soundbar has the connections you need to connect your primary source device – don’t buy a soundbar with only HDMI eARC if your TV doesn't have it!

Now, let’s talk about features that can seem important but aren't critical for a beginner. “Dolby Atmos” and “DTS:X” are surround sound technologies that create a three-dimensional audio experience by simulating sounds coming from above. While these technologies can be impressive, they require specific room acoustics and carefully positioned speakers to work effectively. Most soundbars offer simulated height effects – where the speaker upwards fires towards the ceiling to mimic overhead sounds – but this is often less convincing than true Atmos or DTS:X. You won't notice a huge difference if you’re not sitting directly in front of your TV. Similarly, “object-based audio” (like Dolby Digital Plus) is more about how sound is encoded rather than the actual quality of the sound itself. Don’t worry too much about these advanced features at this stage; focus on getting a soundbar that delivers clear and balanced sound across all frequencies.

Finally, consider the size and design of the soundbar itself. Soundbars come in various lengths and widths, so measure your available space carefully before making a purchase. Some soundbars are designed to sit directly on top of your TV stand, while others can be wall-mounted – this is often a more aesthetically pleasing option but requires additional installation. Don’t overspend on fancy finishes or premium materials; the audio quality will generally be determined by the internal components rather than the exterior design. Remember that these are all details to consider after you've chosen a soundbar based on channels, power and connectivity – it is far more important to focus on those core elements first.
