TVs today might have cutting-edge display technology, but when it comes to sound quality, their built-in speakers often fall flat. A soundbar is a game-changing upgrade that enhances your audio experience without the bulk or complexity of a full home theatre system. Whether you’re watching an action-packed movie, gaming, or simply listening to your favourite playlist, the right soundbar delivers immersive audio that transforms your space.

But picking the perfect soundbar can feel overwhelming with so many options available. From understanding channel configurations to connectivity options like Bluetooth and HDMI ARC, knowing what to look for will help you choose a model that meets your needs and budget. This guide will walk you through everything you need to know to shop smartly.

Understanding Channels and Audio Formats

When shopping for a soundbar, one of the first things to understand is its channel configuration and audio format compatibility. These features determine how sound is distributed and the overall quality of your listening experience.

What Do Channel Configurations Mean?

Soundbar channels typically come as 2.0, 2.1, 3.1, 5.1 and so on. The first number refers to the number of speakers in the bar itself, while the “.1” refers to a subwoofer (either built-in or external).

• 2.0 Channel: Two channels (left and right). Suitable for basic TV viewing or casual music listening.
• 2.1 Channel: Adds a subwoofer for deeper bass—ideal for movies and games.
• 3.1 Channel: Includes a centre channel for clearer dialogue.
• 5.1 Channel: Surround sound with additional rear channels for immersive audio.
• 7.1 or 9.1 Channels: Premium options with more channels for a cinema-like experience.

If you’re looking for a soundbar that creates lifelike, 3D soundscapes, a 5.1 or higher system might be worth the investment. However, for a compact living room setup, sticking with a 2.1 or 3.1 system should suffice.

Dolby Atmos and DTS:X for Immersive Sound

Modern Dolby Atmos soundbars and DTS:X-enabled systems go a step further by delivering overhead sound, creating an enveloping audio experience. These formats make it feel like sound is moving above and around you.

Tip: if a soundbar claims to support Dolby Atmos, check whether it has upward-firing drivers (speakers pointing upwards). Without them, the Atmos experience may be simulated and less immersive.

Subwoofers and Bass Management

Bass is crucial for creating a rich, satisfying audio experience. Whether you’re drawn to the rumbling sound effects of an action movie or the deep beats of a favourite song, a subwoofer can elevate your experience. But what type is best?

External Subwoofer vs. Built-In Bass

• External Subwoofer: Offers deeper, more powerful bass. However, it does require extra space.
• Built-In Subwoofer: Saves on space but may not deliver the same powerful low frequencies as a dedicated unit.

Wireless Subwoofers

Many wireless soundbars come with subwoofers that connect via Bluetooth. This setup allows you to place the subwoofer anywhere in the room, optimising your bass placement without worrying about cables. Just ensure your wireless devices don’t interfere with your home Wi-Fi.

Pro Tip: Place your subwoofer near a corner or a wall to amplify bass resonance without cranking up the volume.

Connectivity and Ports

Your ideal soundbar should make it simple to connect to your devices while supporting the highest-quality audio formats. Here’s what you should know about connectivity options:

HDMI ARC and eARC

HDMI ARC (Audio Return Channel) lets you transmit audio from your TV to the soundbar with a single cable. If you want to stream high-bandwidth formats like Dolby Atmos or DTS:X, look for eARC – its higher bandwidth allows for lossless audio quality.

Optical, AUX, and USB

• Optical connections are reliable but can’t carry advanced audio formats like Dolby Atmos.
• AUX is good for connecting old-school devices but offers lower sound quality.
• USB ports allow you to play music directly from a flash drive or update the soundbar’s firmware.

Bluetooth and Wi-Fi

For wireless streaming, most modern soundbars feature Bluetooth, allowing you to play music right from your phone, tablet, or laptop. However, Wi-Fi offers superior audio quality and multi-room compatibility with systems like AirPlay or Chromecast.

If hands-free control appeals to you, some soundbars come equipped with built-in Amazon Alexa or Google Assistant for voice control.

How Much Power Does My Soundbar Need?

A soundbar’s wattage determines how powerful and loud it can get, making it an essential factor to consider if you want immersive audio. However, higher wattage doesn’t always guarantee better performance, especially in small spaces where too much power can lead to distorted sound or overwhelm the room’s acoustics. It’s important to balance wattage with the size of your space and your specific listening needs.

RMS vs. Peak Power

• RMS (Root Mean Square) represents continuous power output. This figure gives you a more realistic idea of how the soundbar will perform day-to-day.
• Peak Power indicates the maximum sound a soundbar can produce momentarily, but it’s not as reliable a measure of quality.

Room Size Matters

• Small Rooms (e.g., bedrooms): Look for 100–200W RMS.
• Larger Rooms (e.g., living rooms): Opt for 300W or more to fill the space effectively.

Extra Soundbar Features to Watch For

Soundbars come loaded with features that enhance their functionality and your listening experience. Below are some popular extras to consider:

Sound Modes and Presets

Many soundbars offer presets tailored for specific types of content:

• Cinema Mode amplifies effects for films.
• Music Mode balances bass and treble for better clarity.
• Voice Enhancement Mode makes dialogue sharper—ideal for podcasts or dramas.
• Night Mode reduces volume spikes for late-night viewing.

Placement and Mounting

Where you place your soundbar matters. Wall-mounted soundbars can save space and improve sound dispersion, while stand placement may offer easier access to those with limited DIY skills. If mounting blocks your TV’s remote sensor, look for soundbars with an IR repeater.

Brand and Budget

Premium brands like Sonos, Bose, and LG often come with higher price tags, but budget-friendly options from Vizio or TCL can offer surprising quality. Check out our guide on the Top Soundbars 2025 to find something to suit every budget.

Refurbished Models

Consider refurbished or clearance soundbars to snag high-end features at a fraction of the cost.

Price Comparison and Finding Deals

Shopping smart can save you a bundle. Keep an eye out for deals during major sales like Black Friday or Boxing Day sales. Compare prices online for the largest selections and user reviews but don’t underestimate the value of in-store sound tests to get a sense of the system’s quality. Websites like PricePop make price comparisons quick and easy.
