Choosing Your First Soundbar: A Buyer's Checklist

Modern TVs are gorgeous and impossibly thin, which is exactly why they sound so thin too. There is simply nowhere inside a 25mm chassis to put a speaker that moves real air, and a soundbar is the most sensible fix. But the category has quietly turned into a thicket of channel counts, spatial-audio logos, and connection standards, and it is easy to overpay for features you will never use. This checklist is the order I actually work through when a friend asks me what to buy.

Start with the honest question: what problem are you solving?#

Before you look at a single spec, decide what is actually bothering you. In my experience most first-time buyers fall into one of two camps, and they need very different things.

• "I just want to hear dialogue clearly." You are the majority. You are not chasing a home cinema; you want the news anchor and the mumbling prestige-drama lead to be intelligible without riding the volume remote. A modest bar, even a single-piece one, will transform your evenings.
• "I want movies to feel like an event." You care about the low-end punch of an explosion and the sense of a room filling with sound. You need a subwoofer and, ideally, some height or surround capability.

Naming your camp up front stops you from buying a five-figure-looking spec sheet to solve a dialogue problem, or buying a slim single bar and being disappointed that action films feel flat. Almost everything below flows from this one decision.

Decode the channel numbers#

Soundbars are sold with figures like 2.0, 2.1, 3.1, 5.1.2, and 7.1.4. It looks like marketing noise, but the format is simple once you know the pattern.

• The first number is the count of horizontal channels (left, right, center, surrounds).
• The second number is the subwoofer count (the ".1").
• The third number, when present, is the upward-firing height channels used for Dolby Atmos (the ".2" or ".4").

So a 3.1 bar has left, right, a dedicated center for dialogue, and a sub. A 5.1.2 adds two surround channels and two height drivers. Here is the caveat I wish more people heard: a higher channel count on a single bar is often a promise the hardware cannot keep. A "5.1.2" bar with no separate speakers is firing all of those channels from one enclosure and bouncing height effects off your ceiling. The processing is clever, but it is not the same as speakers physically placed around you. Do not pay for surround channels you have no way to place, and be skeptical of virtualized surround from a single bar in a large or oddly shaped room.

The subwoofer question#

If I could give a first-time buyer one piece of advice, it is this: the jump from no sub to a sub is bigger than almost any other upgrade in the category. A soundbar's cabinet is too small to produce genuine low bass, and no amount of DSP invents frequencies the driver cannot move.

Wireless is fine, placement still matters#

Most subs that ship with a bar are "wireless," meaning they pair over their own radio link and only need a power outlet. That is genuinely convenient. But wireless does not mean invisible to physics:

• Bass is non-directional, so you have real freedom in where you put the sub, but corners reinforce output and can make it boomy.
• Keep it on the same wall or nearby if the pairing feels laggy in a big room, though most modern systems handle 8 to 10 metres without trouble.
• If the low end sounds one-note, move the sub a foot or two before you touch any settings. Room placement outperforms EQ almost every time.

If a bar you like offers a sub-less base model and a "+sub" bundle, the bundle is nearly always the better value than adding a sub later.

Check the connections before anything else#

This is the section people skip and then regret. Pull your TV away from the wall and actually look at its ports.

HDMI eARC is what you want#

The single most important connector is HDMI eARC (enhanced Audio Return Channel). It carries high-bitrate, lossless, and object-based formats like Dolby Atmos from your TV to the bar over one cable, and it lets your TV remote control the bar's volume via HDMI-CEC. Plain ARC (without the "e") works too but is bandwidth-limited and will typically fall back to compressed audio.

• Confirm your TV has an HDMI port labeled ARC or eARC — usually only one of its ports is.
• If your TV is older and only offers optical (Toslink), you can still get great stereo and standard surround, but optical cannot carry full-fat Atmos. That may be perfectly fine for a dialogue-first buyer.
• If you want to plug sources (a game console, a 4K player) into the bar rather than the TV, count the bar's HDMI inputs. Many budget bars have none — they are eARC-only pass-through devices.

Get this wrong and you can buy a premium Atmos bar that only ever receives compressed sound because your TV connection cannot pass the good stuff.

Match the size to your room and TV#

A soundbar that is dramatically narrower than your TV looks odd and usually images poorly; one that is wider than your furniture is a placement headache. Two practical rules:

1. Width: aim for a bar roughly as wide as your TV, give or take. A 65-inch TV pairs naturally with a bar in the 100 to 120cm range.
2. Height: measure the clearance between your TV stand and the bottom of the screen. A tall bar can block the bottom of the picture or the TV's IR receiver. If clearance is tight, look for a low-profile bar or plan to wall-mount.

Room size matters more than the box implies. A single compact bar can fill a bedroom effortlessly and feel completely overwhelmed in a large open-plan living room. Bigger rooms want more drivers, a capable sub, and real power headroom — not just a louder volume setting.

Features worth paying for — and ones to ignore#

After hundreds of hours with these systems, here is where I think the money is well spent.

Worth it for most people:

• A dedicated center channel (the "3" in 3.1). This is the biggest single upgrade for dialogue clarity, because voices get their own driver instead of being blended into left and right.
• A physical remote or good app with a clear dialogue-enhancement mode and independent sub level. You will use these constantly.
• Automatic room calibration, if offered, genuinely helps in awkward rooms — though it is a bonus, not a dealbreaker.

Easy to overvalue:

• Dolby Atmos on a single bar with no height speakers. The up-firing effect is subtle at best and depends heavily on a flat, reflective ceiling of the right height. It is a nice-to-have, not a reason to stretch your budget.
• Built-in streaming and voice assistants. Your TV and phone almost certainly already do this. Do not pay a premium for a smart platform inside a speaker.
• Extreme channel counts you cannot physically accommodate. A 7.1.4 badge means nothing if the rear speakers stay in the box.

A quick pre-purchase checklist#

Run this list before you check out:

1. Which camp are you in — clear dialogue, or cinematic impact?
2. Does your TV have eARC, ARC, or only optical, and does that match the formats you want?
3. Is there a subwoofer, and if the bar is sold with and without one, can you afford the bundle?
4. Is the bar's width and height right for your TV and furniture?
5. Do you need HDMI inputs on the bar for external sources?
6. Are you paying for channels or smart features you will actually use?

The bottom line#

The best first soundbar is not the one with the longest spec sheet; it is the one whose features you can actually use in your room, fed by a connection that can carry them. For most people that means a 3.1 system with a wireless sub over HDMI eARC — enough for crisp dialogue and real bass without paying for virtualized surround that a single bar struggles to deliver. Get the fundamentals right and you will forget the specs entirely, which is exactly the point: good audio should disappear and leave only the thing you are watching.
