How to Choose a Soundbar

Choose for your room

Three soundbar options explained

Price and listing check — 28 September 2026: Q600F: $795 at Harvey Norman; Beam Gen 2: $639 at Sonos; Q990H: $1,599 from Samsung’s official eBay store, plus delivery. Prices are AUD and may change. Confirm local stock and checkout totals. These illustrate three different setups, not a lowest-price ranking.

The short answer

• For clearer television dialogue: choose a 3.0 or 3.1-channel soundbar with a genuine centre channel and useful voice controls.
• For everyday films and sport: choose a good 3.1 or 5.1 system with HDMI ARC or eARC.
• For cinema impact: choose a system with a capable subwoofer and real rear speakers.
• For convincing Dolby Atmos: look for physical upward-firing drivers and, ideally, rear speakers with their own height channels.
• For an apartment: prioritise dialogue and controlled bass rather than buying the largest subwoofer.
• For gaming: verify eARC or complete 4K/120, VRR, ALLM and HDR pass-through before routing a console through the bar.

Do not buy by wattage or channel count alone. A thoughtfully designed 3.1 soundbar can sound clearer and more balanced than a cheap product advertising many virtual channels.

Shortlist at a glance

How these examples were chosen

These three Australian models illustrate different buying decisions: a separate-subwoofer system, a compact expandable bar and a full surround package. The comparisons use manufacturer specifications and retailer listings, with room fit, included hardware and connection limits given priority. This is research-led guidance; we have not carried out hands-on testing of these units.

The three product options in detail

Bar + sub option

1. Samsung HW-Q600F/XY

A straightforward example of the bar-and-subwoofer approach.

3.1.2 channelsSubwoofer includedHDMI eARC

The Q600F combines a centre channel, two height channels and a wireless subwoofer. Its bar measures 1,030 × 57 × 105 mm (W × H × D), so check both the TV feet and screen clearance.

One HDMI source input, HDMI eARC, optical and Bluetooth cover common TV setups. There is no Wi-Fi music streaming. It is an option to compare at a good discount, not an automatic best-value purchase at the current $795 listing.

Why consider it

• Separate bass unit included.
• Physical height channels.
• Low-profile bar.

What to check

• Rear speakers are not included.
• No Wi-Fi streaming.
• Compare newer alternatives before paying $795.

Best suited to: A household wanting a conventional bar and subwoofer, if the price and TV fit make sense.

Compact option

2. Sonos Beam (Gen 2)

A compact starting point for a smaller room.

651 mm wideVirtual AtmosHDMI eARC

The Beam is 651 × 68 × 100 mm (W × H × D). Speech Enhancement and Night Sound suit dialogue and quieter viewing; Wi-Fi and AirPlay 2 add music options.

Its Atmos height effect is virtual. A subwoofer and rear speakers cost extra. Trueplay tuning requires a supported iOS device, and there is no extra HDMI input for a player or console. The $639 official-store offer applies to Beam Gen 2, not the newer Beam Ultra.

Why consider it

• Compact cabinet.
• Speech and night controls.
• Optional Sonos system expansion.

What to check

• No physical height drivers.
• Accessories increase the total cost.
• Trueplay needs supported iOS hardware.

Best suited to: A smaller room where fewer boxes and convenient music playback matter.

Beam Gen 2Sonos

Full surround

3. Samsung HW-Q990H/XY

The complete surround-package example for a movie-focused room.

11.1.4 channelsRear speakers included4K/120 pass-through

The Q990H includes its subwoofer and rear speakers in an 11.1.4-channel package. Samsung lists HDMI eARC, up to 4K/120 video pass-through and SpaceFit Sound Pro calibration.

The bar is 1,232 × 70.8 × 138 mm (W × H × D). Allow space and power for all four components. Real rear speakers are a stronger reason to consider it than the channel count alone; ceiling reflections still depend on the room.

Samsung’s official Australian eBay store listed it at $1,599 plus delivery when checked. Confirm the seller, exact /XY model and delivered total.

Why consider it

• Subwoofer and two rears included.
• Physical surround and height channels.
• Room calibration.

What to check

• More space and power points required.
• Wide soundbar.
• Excessive for some small rooms and budgets.

Best suited to: A movie or gaming household able to place and power the rear speakers properly.

Q990HeBay

Start with the problem you want to solve

Before comparing formats and channel numbers, decide what disappoints you about the television's current sound.

• Are voices difficult to understand?
• Does the sound become harsh when you increase the volume?
• Do films lack bass and impact?
• Do you want effects to come from behind the sofa?
• Do you want music to sound full without buying a separate stereo?
• Are you trying to keep cables and speakers out of the room?
• Do you need low-volume listening that will not disturb neighbours?

A compact all-in-one bar may solve dialogue and volume problems. It will not recreate the physical bass of a large subwoofer or the directionality of speakers behind you. Spend money on the improvement you will actually notice.

Soundbar or full home theatre?

A soundbar packages several speakers and amplifiers into one long cabinet. It is easier to install, uses less space and creates less cable clutter than a receiver with separate speakers.

A traditional home-theatre system remains the stronger option when you want:

• Precise speaker placement around a large room.
• Greater upgrade and replacement flexibility.
• More powerful, effortless output.
• Several HDMI source inputs.
• Full-size front speakers for serious music listening.
• Ceiling speakers for the most convincing height effects.

A premium soundbar system with a subwoofer and wireless rears can be remarkably immersive, but it is still a packaged ecosystem. Expansion is normally limited to the compatible accessories offered by that manufacturer.

Understand soundbar channel numbers

Soundbars commonly use numbers such as 2.0, 3.1, 5.1.2 or 11.1.4. In the conventional description:

• The first number represents the main ear-level channels.
• The second number represents the subwoofer or low-frequency channel.
• The third number represents height channels.

A 3.1 system normally has left, centre and right channels plus a subwoofer. A 5.1 system adds surround channels. A 5.1.2 system adds two height channels intended to reproduce sound above the listener.

Marketing can complicate this. Some systems count internal drivers, side-firing units or processed “virtual” channels differently. Read the speaker layout and included components rather than assuming two products with the same channel number work identically.

Why a centre channel matters for dialogue

Film and television mixes normally place much of the dialogue in the centre channel. A 3.0 or 3.1 soundbar with a dedicated centre speaker can anchor voices near the middle of the screen and separate them from music and effects.

This is not an absolute guarantee. Driver quality, processing and the mix still matter. However, if speech clarity is your priority, a well-designed centre channel is a better starting point than a 2.0 or 2.1 bar trying to create a phantom centre between its left and right speakers.

Also look for:

• A dialogue, voice or speech-enhancement mode.
• Independent centre-channel adjustment.
• Night mode or dynamic-range control.
• Clear operation at low volume.
• Minimal harshness in the upper midrange.

Voice enhancement should make speech easier to follow without turning every actor thin, nasal or unnaturally loud.

Do you need a subwoofer?

A separate subwoofer reproduces low frequencies that a slim soundbar cannot move enough air to deliver convincingly. It adds weight to film effects, music, games and even deeper voices.

A subwoofer is worthwhile if you want:

• Explosions and action scenes with physical impact.
• Fuller music and concert playback.
• A larger room filled without making the soundbar strain.
• A cinema-style experience rather than only clearer television.

An all-in-one soundbar without a subwoofer is easier in a bedroom, small apartment or minimalist lounge. Some premium single bars produce impressive upper bass, but they cannot completely replace a capable standalone subwoofer.

Apartment and neighbour considerations

Deep bass travels through walls, floors and building structures more readily than dialogue. A powerful subwoofer can disturb neighbours even when the overall volume does not seem excessive in your room.

Apartment buyers should look for adjustable subwoofer level, night mode and good dialogue at low volume. Position the subwoofer away from shared walls, consider suitable isolation feet to reduce furniture or floor vibration, and reduce bass during quiet hours. Isolation does not stop deep bass travelling between homes.

Do not place the subwoofer inside a closed cabinet. Wireless describes its audio connection; it still needs mains power and space to ventilate and move air.

Real rear speakers versus virtual surround

A soundbar can use side-firing speakers and digital processing to bounce or simulate sound around the room. This may create a wider front stage and a sense of space, particularly in a symmetrical room with useful side walls.

Physical rear speakers remain more reliable when you want effects clearly behind or beside the listening position. They are especially valuable for films and games mixed with discrete surround information.

“Wireless rear speakers” are rarely completely wire-free. They may connect wirelessly to the soundbar, but each speaker or their shared wireless amplifier still needs power. Check the number and location of power points before buying.

Dolby Atmos explained for soundbars

Dolby Atmos is an object-based immersive-audio format that can place sounds above as well as around the listener. Soundbars approach the height layer in two main ways:

• Physical upward-firing drivers: speakers direct sound toward the ceiling so it reflects down to the listening area.
• Virtual height processing: digital processing creates a psychoacoustic impression of height without dedicated upward-firing drivers.

Physical height drivers generally provide the more convincing result, but the room is important. Dolby says upward-firing enabled speakers work best with a flat, acoustically reflective ceiling approximately 2.3 to 4.3 metres high.

High, vaulted, angled or heavily absorbent ceilings can weaken the reflection. Virtual processing may still add spaciousness, but a Dolby Atmos logo does not guarantee obvious sound directly overhead.

DTS:X and DTS Virtual:X

DTS:X is another immersive object-based audio system supported by selected films, discs, games, televisions and soundbars. DTS Virtual:X is processing designed to create virtual surround and height effects from systems without a complete physical speaker layout.

Check the content and equipment you use. Some televisions do not decode or pass every DTS format, while some soundbars focus on Dolby support. Disc collectors and home-media users should investigate DTS compatibility more carefully than households relying only on mainstream streaming services.

A format logo does not guarantee great sound

A compact inexpensive soundbar may accept a Dolby Atmos signal but reproduce it mostly through virtual processing. A larger system with more physical speakers, better drivers and stronger calibration can create a much more convincing result.

Judge the complete design:

• Physical centre, side, rear and height speakers.
• Driver quality and cabinet size.
• Subwoofer extension and control.
• Room calibration.
• Maximum clean output.
• Audio-format compatibility.
• How the system sounds with ordinary stereo and television material.

You will spend more time listening to ordinary dialogue, music and compressed broadcasts than to spectacular Atmos demonstration clips.

HDMI ARC versus HDMI eARC

HDMI ARC allows a compatible television to send audio back to a soundbar through the labelled HDMI connection. It can also allow power and volume control through HDMI-CEC, reducing the need to use two remotes.

HDMI eARC is the newer, higher-bandwidth version. HDMI Licensing Administrator says eARC supports uncompressed multichannel audio and high-bitrate formats including Dolby TrueHD, Dolby Atmos, DTS-HD Master Audio and DTS:X where the connected products support them.

For a new mid-range or premium purchase, eARC is the preferred connection. ARC remains adequate for many compressed streaming soundtracks and simple systems.

Does Dolby Atmos always require eARC?

No. Streaming services often deliver Dolby Atmos using compressed Dolby Digital Plus, which can work through compatible ARC equipment. Lossless Dolby Atmos carried with Dolby TrueHD normally requires eARC or a direct HDMI connection through compatible equipment.

The complete chain must agree:

1. The program or game must include the format.
2. The app, disc player, console or streaming box must output it.
3. The television must decode or pass it correctly.
4. The selected HDMI connection must carry it.
5. The soundbar must support and reproduce it.

A Dolby Atmos badge on the soundbar cannot make the television pass a format it does not support.

Optical audio: useful but limited

Digital optical audio can be reliable and useful with an older television. It can carry stereo PCM and common compressed surround formats, but it lacks the bandwidth and integrated control available through modern eARC.

Optical normally will not provide the complete high-bandwidth immersive-audio experience, and power or volume control may require separate configuration. Use it when HDMI ARC or eARC is unavailable or unreliable, not as the automatic first choice for a new premium system.

Bluetooth should not be your main TV connection

Bluetooth is convenient for playing music from a phone and may be acceptable for casual television listening. It can introduce compression, connection instability and lip-sync delay, depending on the devices and codec.

A wired HDMI connection is normally the safer permanent television link. Wi-Fi can support useful music services and manufacturer-specific wireless TV audio, but compatibility and latency vary by ecosystem.

Check the television's audio capabilities

Before buying a soundbar, record the complete television model number and confirm:

• Whether it has ARC or eARC.
• Which HDMI port carries the return channel.
• Which Dolby and DTS formats it can pass from built-in apps and HDMI sources.
• Whether it can output multichannel PCM.
• Its HDMI-CEC control settings.
• Whether the stand position leaves room for the bar.
• Whether a brand-matching speaker feature is supported.

Pass-through capability can differ between internal apps and external HDMI devices. A television that plays one format itself may not pass the same format from a console or disc player.

Soundbar HDMI inputs and video pass-through

Some soundbars provide one or more HDMI inputs so a console, disc player or streaming box can pass video through the soundbar to the television. Others provide only an HDMI output for ARC or eARC.

If you connect a gaming device through the soundbar, verify the complete combination you require:

• 4K at 120 Hz or higher.
• Variable Refresh Rate.
• Auto Low Latency Mode.
• HDR10, Dolby Vision or HDR10+ as required.
• Full colour and bit-depth support.
• Low latency and reliable switching.

A soundbar advertised with “4K pass-through” may support only 4K at 60 Hz or may omit a particular HDR or gaming feature. Gamers can avoid this bottleneck by connecting the console directly to the television and returning audio through eARC.

Measure before you buy

Soundbars differ significantly in width, height and depth. Measure the available space and check:

• Whether the bar fits between the television's feet.
• Whether it blocks the bottom of the picture.
• Whether it covers the television's infrared receiver.
• Whether upward-firing drivers have clear space above them.
• Whether cables can bend without being crushed.
• Whether the cabinet is deep and strong enough.
• Whether the subwoofer fits without being trapped in furniture.

Some television stands have a soundbar position or adjustable height. Confirm the exact Australian model rather than assuming a feature shown on an overseas version is included.

Place the soundbar correctly

Centre the soundbar beneath the television so dialogue appears to come from the screen. Keep its front edge clear of the cabinet rather than pushing it behind a shelf lip.

Do not place objects over upward-firing or top-mounted speakers. If wall mounting, use the manufacturer-approved brackets and spacing. The bar should not obstruct television ventilation or hang from plasterboard without suitable structural support.

For side-firing virtual or reflected surround, a reasonably symmetrical room with useful walls can help. A large open side, heavy curtains or an irregular layout may reduce the effect.

Place the subwoofer by listening, not guessing

Room boundaries can dramatically change bass. A corner often increases output but may make particular notes boomy. The middle of an open room can produce weak or uneven bass.

Start near the front wall with some clearance, then test several realistic positions from the main seat. Use familiar music and scenes containing both deep and upper bass. Choose the position that sounds even, not merely the loudest.

Wireless subwoofers still need a power outlet and can experience interference or dropouts. Keep them within the manufacturer's recommended range and do not hide them inside closed furniture.

Room size and listening distance

A compact bar may be ideal in a bedroom but struggle to fill a large open-plan lounge. A very wide premium system can be awkward beneath a small television. Powerful systems can still play quietly, but their extra bass capability may be unnecessary where neighbours limit listening levels.

For a larger room, prioritise:

• A substantial soundbar with wide speaker spacing.
• A capable subwoofer rather than exaggerated wattage claims.
• Real rear speakers.
• Room calibration.
• Clean output at the required seating distance.

Open-plan rooms are acoustically difficult because sound and bass escape into connected areas. Buy for the listening zone rather than expecting a soundbar to pressurise the entire house.

Room calibration is worth having

Room-calibration systems use microphones and test sounds to adjust timing, level and frequency response for the space. They can help integrate the subwoofer, balance rear speakers and reduce some room-related problems.

Calibration cannot fix impossible placement, an unsuitable ceiling or a weak speaker. Run it in normal listening conditions, keep the room quiet and place the measuring phone or microphone where the manufacturer directs.

After calibration, listen before making changes. You may still prefer to adjust centre, rear, height or subwoofer levels slightly for your content and hearing.

Matching the soundbar brand to the television

You do not normally need to match brands. HDMI ARC and eARC are designed to connect compatible equipment from different manufacturers.

Matching can unlock additional features:

• Samsung Q-Symphony can combine compatible Samsung television and soundbar speakers.
• LG WOW Orchestra can use compatible LG television and soundbar speakers together.
• Sony Acoustic Center Sync can use a compatible BRAVIA television as part of the centre presentation.
• Brand-specific menus may expose soundbar controls directly on the television.

Compatibility is model-specific and can change by year. Do not buy a same-brand soundbar merely for the logo; confirm the exact television and soundbar combination supports the feature you want.

Music performance needs separate attention

A system that creates spectacular movie effects may not automatically reproduce stereo music naturally. If music matters, test vocals, acoustic instruments, bass lines and stereo imaging without excessive surround processing.

Check for the services and connections you use:

• Bluetooth.
• AirPlay.
• Google Cast.
• Spotify Connect.
• Other direct streaming services.
• USB or analogue input if required.
• Multiroom compatibility.

A direct Wi-Fi music connection can be more convenient and stable than keeping a phone connected over Bluetooth.

Expandability can save money later

Some soundbars can add a compatible subwoofer and rear speakers after purchase. Others are permanently limited to the original unit or bundled components.

Before choosing an expandable system, check:

• Which accessories are compatible with the exact model.
• Whether the accessories are officially sold in Australia.
• Whether two subwoofers are supported.
• Whether rear speakers add real channels or mirror existing ones.
• Whether accessories require a separate wireless receiver.
• The total system price rather than the cheap starting price.

Proprietary wireless speakers normally cannot be transferred to another brand later.

Wattage is a poor shortcut

Manufacturers may quote peak power, total system power or RMS power under different test conditions. The numbers are not always directly comparable.

Higher wattage does not guarantee clearer dialogue, deeper bass or lower distortion. Driver size, amplifier quality, cabinet design, processing and room interaction matter more than one large number on the box.

Listen for clean sound at the loudest level you will realistically use. Harshness, pumping bass or compressed dynamics are more meaningful than the advertised wattage.

Do not forget power points and cables

A complete “wireless” package may need power for:

• The soundbar.
• The subwoofer.
• Each rear speaker or their shared receiver.
• The television and source devices.

Plan safe power access without running extension leads beneath rugs or over walkways. Use the supplied power equipment and follow the manufacturer's ventilation instructions.

For eARC and demanding video pass-through, use an appropriate certified HDMI cable. An expensive cable does not improve sound once the required digital signal is carried reliably.

Test with ordinary content

Showroom demonstrations are designed to impress with loud action scenes and exaggerated bass. Ask to hear:

• Quiet dialogue between two people.
• A busy action scene with voices over music and effects.
• Free-to-air news or sport.
• A familiar stereo music track.
• Low-volume late-night listening.
• A genuine Atmos scene if height performance matters.

Turn off demonstration modes and compare systems at similar perceived volume. A slightly louder product often seems better during a quick comparison even when it is less balanced.

Common setup problems

No sound: use the labelled ARC or eARC ports on both products, select the television's external audio output and enable HDMI control where required.

Atmos does not appear: confirm the actual program, subscription, app, source, television pass-through setting, HDMI connection and soundbar format support.

Lip-sync delay: update both products, test another source, disable unnecessary processing and adjust the audio-delay control carefully. Bluetooth is more prone to delay than HDMI.

The soundbar does not turn on with the TV: check HDMI-CEC settings, which use different brand names, and confirm the ARC or eARC connection.

The subwoofer drops out: reduce wireless interference, check distance, restart pairing and move the unit away from obstructing furniture or network equipment.

Voices are still unclear: raise the centre channel slightly, reduce excessive bass, disable overaggressive surround modes and try the dialogue setting.

My recommendation by buyer

• Older listener or dialogue-first household: a quality 3.0 or 3.1 bar with centre adjustment and voice enhancement.
• Small bedroom: a compact all-in-one bar with HDMI ARC and good low-volume clarity.
• Apartment: a controlled 3.1 system or premium all-in-one bar with night mode.
• Family lounge: a 3.1 or 5.1 system with eARC, a subwoofer and room calibration.
• Movie enthusiast: physical rear and upward-firing speakers, a capable subwoofer and broad format support.
• Serious gamer: eARC or verified 4K/120, VRR, ALLM and HDR pass-through.
• Music-first buyer: audition stereo performance carefully and consider whether proper powered speakers or a hi-fi system would suit better.
• Large open-plan room: choose a substantial system with real rears, strong calibration and enough clean output—or consider a receiver and separate speakers.

Questions to answer before buying

1. Is clearer dialogue, deeper bass or surround sound my main goal?
2. Does the soundbar physically fit without blocking the television?
3. Does my television provide ARC or eARC?
4. Which formats can the television pass from apps and HDMI devices?
5. Does the system have a genuine centre channel?
6. Are the subwoofer and rear speakers included or optional?
7. Where will every component receive power?
8. Will upward-firing speakers work with my ceiling?
9. Does gaming pass-through support every video feature I use?
10. Can the system expand later, and what will that cost?
11. Does it sound good with dialogue and music, not only demonstrations?
12. What return and installation conditions apply?

Australian consumer protections

Keep the receipt, model numbers, serial numbers and any written compatibility advice. Products sold in Australia come with automatic consumer guarantees, including that they be of acceptable quality, match their description and be fit for a purpose you disclosed to the seller.

If you need the soundbar to pass 4K/120 gaming, reproduce a particular audio format or work with a specific television, give the retailer the complete model numbers and ask for written confirmation before buying.

A manufacturer's warranty is additional to Australian Consumer Law. A retailer's voluntary change-of-mind policy is different from your rights when equipment is faulty, misdescribed or not fit for the disclosed purpose.
