How these examples were chosen

Physical Atmos

Samsung Q-Series HW-Q800H/XY

The featured example for understanding top- and side-driver clearance.

5.1.2 channelsPhysical height speakersSpaceFit Sound Pro

This 5.1.2-channel system has physical height speakers and SpaceFit Sound Pro. Give the top and ends of the bar unobstructed paths into the room. Its compact subwoofer reduces the cabinet space needed, but still belongs in a position that sounds even from your seats.

Why it suits this role

• Physical up-firing speakers for suitable ceilings
• Compact separate subwoofer

What to consider

• Overhead reflections depend on ceiling and seating
• The bar still needs clear space above and beside it

Best suited to: A room with a suitable ceiling and space for unobstructed top and side speakers.

Slim bar option

JBL Bar 500MK2 (JBLBAR500M2BLKAS2)

A slim soundbar with a separate 10-inch wireless subwoofer.

5.1 channelsVirtual AtmosSound calibration

The 5.1-channel Bar 500MK2 uses virtual Dolby Atmos and MultiBeam processing; it does not have dedicated up-firing height channels. Its bar is only 50.5 mm high, but you must still measure TV clearance. Allow floor space for the larger subwoofer and keep its rear port clear.

Why it suits this role

• Low bar height helps beneath many screens
• Model-specific sound-calibration procedure

What to consider

• Virtual height effects, rather than up-firing speakers
• Subwoofer needs more floor space than Samsung’s compact unit

Best suited to: A low-clearance TV setup with enough floor space for its subwoofer.

Simple 2.1 option

Sony HT-S400 (HTS400)

A simpler 2.1-channel system where placement and manual levels do the work.

2.1 channelsHDMI ARCVoice and Night modes

The HT-S400 has a wireless subwoofer, HDMI ARC, Voice mode and Night mode. It does not support Dolby Atmos or automatic room calibration. Centre the bar below the TV, compare subwoofer positions and adjust its level with familiar programmes and music.

Why it suits this role

• Simple connection and everyday controls
• Lower checked price than the other examples

What to consider

• No Dolby Atmos or automatic room calibration
• Tall, deep subwoofer still needs a suitable floor position

Best suited to: A straightforward TV-audio upgrade without height-channel or calibration requirements.

The short answer

Place the soundbar directly below the television, centred with the screen and as close to seated ear level as the furniture allows. Keep its front, sides and top unobstructed, particularly when it has side-firing or up-firing Dolby Atmos drivers.

Start with the subwoofer near the front wall, slightly away from the corner and nearby furniture. Listen from the main seat, try several positions and keep the location that produces strong, even bass without excessive boom.

Do not hide either component inside closed furniture. After settling on the positions, run the soundbar's room-calibration process if supported, then adjust levels using familiar content.

Where should the soundbar go?

For most installations, the soundbar belongs directly below the television. This keeps dialogue connected to faces on the screen and gives left-to-right effects a natural relationship with the picture.

The bar should be level and centred with the television rather than centred with an off-set cabinet. A small horizontal error will not destroy the sound, but an obviously off-centre position can make dialogue and movement feel disconnected.

Place it near the front edge of the entertainment unit when possible. Pushing it against the rear wall or deep under a shelf can create reflections and block side-firing drivers.

Can the soundbar sit above the television?

It can, but below the television is normally better. Dialogue arriving from far above the screen is less natural, and many soundbars are designed with their display, controls and Atmos drivers assuming the normal upright orientation.

Above-screen mounting may be necessary when furniture, a fireplace or installation layout leaves no space underneath. Keep the bar close to the screen and follow the manufacturer's mounting orientation.

Never turn a standard soundbar upside down unless its instructions explicitly permit it. Doing so can redirect up-firing speakers towards the floor and place ventilation or controls incorrectly.

How far below the television should it be?

Keep the gap practical and visually balanced. The soundbar should be close enough that voices appear to come from the screen, while leaving enough room for the television's lower edge, remote-control sensor and any downward-facing ventilation.

Samsung's Australian wall-mounting guidance recommends installing its soundbar at least 5 centimetres below a wall-mounted television. Treat that as useful brand-specific guidance rather than a universal rule for every model.

Check both manuals before drilling. Some televisions have sensors, microphones, buttons or cable connections along the lower edge that must remain accessible.

Do not let the soundbar block the screen

Modern soundbars can be surprisingly tall. On a low television stand, the bar may cover the bottom of the picture or interfere with the television's infrared receiver.

Measure the distance between the furniture surface and the bottom of the television before buying. Compare that space with the soundbar's height, including its rubber feet.

If clearance is inadequate, use the television's approved higher stand position, wall-mount the television or mount the soundbar. Do not remove stabilising feet or balance the television on improvised blocks.

Should the soundbar sit at the front or back of the cabinet?

Usually near the front. The soundbar's front grille should not sit behind the lip of the entertainment unit, and its side drivers should have open paths into the room.

A bar positioned deep against the wall can produce early reflections from the cabinet surface. Up-firing drivers may also strike a television overhang or shelf before reaching the ceiling.

Leave enough rear space for HDMI and power cables to bend naturally. A tight cable pressed sharply against the wall can strain the connector.

Can you place a soundbar inside a cabinet?

It is rarely ideal. A cabinet opening can alter the sound, block side-firing channels and trap reflections. Closed doors obviously prevent the bar from working properly.

If cabinet placement is unavoidable, use an open shelf wider and taller than the soundbar, position the front grille flush with the shelf edge and provide ventilation. Avoid models that depend heavily on side or upward reflections.

Do not place the bar behind fabric, ornaments, books or framed photographs. Decorative acoustic fabric can be transparent to sound, but normal household fabric should not be assumed suitable.

Wall mounting versus placing it on furniture

Furniture placement is simpler, easier to change and avoids drilling. It also makes cable access and future replacement straightforward.

Wall mounting creates a clean result and can keep the soundbar aligned with a wall-mounted television. Use the supplied template and brackets or hardware approved for the model.

Confirm the wall material and fixing points before installation. A large premium soundbar is heavier than it looks. Use suitable anchors or professional installation rather than relying on light-duty picture hooks.

Should the soundbar move with a full-motion TV mount?

Attaching the soundbar to a compatible television-mount bracket keeps it aligned when the screen swivels. This is useful in open-plan rooms where the television faces different seating areas.

Check the combined weight rating and VESA compatibility of the mount and soundbar bracket. Make sure the soundbar does not cover connections, ventilation or the lower part of the screen.

A separately wall-mounted bar remains fixed when the television moves, which can make dialogue appear off-centre from angled seating positions.

Placement for Dolby Atmos soundbars

An Atmos soundbar with up-firing speakers directs sound towards the ceiling so it reflects down towards the listener. The top drivers require a clear vertical path.

Do not place the bar under a deep shelf, inside low furniture or directly beneath a television that projects far over it. Move the bar forward until the up-firing drivers can see the ceiling.

Reflected Atmos works best with a flat, hard ceiling at a moderate height. Vaulted, angled, absorbent or exceptionally high ceilings make the reflected path less predictable.

Placement for side-firing soundbars

Side-firing drivers use nearby walls and processing to widen the soundstage. Keep both ends of the bar clear and avoid squeezing it between tall cabinets.

Symmetrical side walls help, but many Australian open-plan rooms have a wall on one side and an open kitchen or hallway on the other. Room calibration can compensate to a degree, but it cannot create a physical reflection where no wall exists.

In a difficult open-plan layout, physical rear speakers often improve surround sound more reliably than moving the soundbar by a few centimetres.

Where should the subwoofer go?

The front of the room is the best starting point, not an absolute rule. Place the subwoofer on the floor near the television wall, with some distance from corners, cabinets and curtains.

Keeping it near the soundbar can make bass feel connected to the front presentation and normally provides a strong wireless link. Low bass is difficult to locate, so the final position may also work beside or behind the sofa if the system allows it.

The room and listening position determine the result. A location that sounds powerful in one seat may produce a bass cancellation in another.

How far should the subwoofer be from the wall?

Begin with a modest gap rather than pressing the cabinet hard against the wall. The product manual may specify minimum clearance for its driver, port, ventilation and wireless connection.

A rear-ported subwoofer needs enough room for air movement. A side-firing driver should not fire directly into the side of a cabinet with only a tiny gap.

There is no universal measurement that suits every design. Start with approximately 10 to 30 centimetres where practical, then follow the manufacturer's clearance requirements and test the result.

Should the subwoofer go in a corner?

A corner usually increases bass output because the nearby walls and floor reinforce low frequencies. This can help a small subwoofer sound stronger, but it can also exaggerate particular notes and create one-note boom.

Start slightly outside the corner. Move closer only if bass is too weak and remains reasonably even. Move it farther away if explosions overwhelm dialogue or certain bass notes dominate.

Do not confuse more bass with better bass. Controlled extension and consistency across the sofa matter more than maximum vibration in one seat.

Can the subwoofer go behind the sofa?

Yes, if the wireless connection remains stable and the bass integrates well. Near-field placement behind the sofa can provide strong impact at lower overall output, which may help in some rooms.

The subwoofer should not touch the sofa or fire directly into loose fabric. Leave space for ventilation, controls and cable access.

Very close placement can make bass feel localised or uneven between seats. If supported, update the room calibration after moving it and reduce the level if the nearest listener receives too much impact.

Can you put the subwoofer inside furniture?

Do not put it inside a closed cabinet. A subwoofer moves substantial air and can make doors, shelves and objects rattle. Enclosure also interferes with wireless reception, ventilation and the intended acoustic design.

An open furniture bay may still create resonances and should only be used when the manufacturer permits it and generous clearance is available.

The cleanest answer is usually to leave the subwoofer on the floor and make it part of the room rather than trying to disguise it completely.

Can the subwoofer lie on its side?

Only if the manufacturer explicitly approves horizontal placement. Feet, drivers, ports, amplifiers and cooling paths are designed for a particular orientation.

Laying a vertical subwoofer down can block a driver or port, damage the cabinet finish and change how vibration enters the floor.

Do not choose a location that requires using the product in an unsupported orientation. Select a more compact system if space is genuinely limited.

What is the subwoofer crawl?

The subwoofer crawl is a practical way to identify positions that produce smoother bass at the main seat.

1. Temporarily place the subwoofer at or very close to the main listening position.
2. Play familiar music or a repeating bass sweep at a sensible level.
3. Move around the edges of the room at subwoofer height.
4. Listen for locations where bass sounds strong, even and controlled.
5. Mark two or three practical positions.
6. Move the subwoofer to each candidate position and test from the sofa.
7. Keep the location that performs best across the important seats.

The method works because acoustic behaviour is broadly reciprocal between the source and listening position. It does not replace measurement equipment, but it is much better than choosing solely by appearance.

Test more than one seat

A subwoofer can sound excellent in the centre seat and weak one cushion away. Room modes create peaks and cancellations that change with position.

Test every seat used regularly. The best practical location is often the one with the most consistent result rather than the strongest bass in one privileged chair.

One soundbar subwoofer cannot always produce even bass across a large open-plan room. Calibration helps, but placement remains the first tool.

Should the subwoofer face the listener?

Not necessarily. Deep bass radiates less directionally than higher frequencies. The driver orientation matters less than the room position, although ports and drivers still need their specified clearance.

Follow the product's normal upright orientation and do not rotate it simply to hide the driver. Test changes from the listening position rather than judging by appearance.

Wireless subwoofer connection problems

A wireless subwoofer still needs mains power and a reliable signal from the soundbar. Thick walls, metal furniture, enclosed cabinets and competing wireless equipment can affect the connection.

If bass cuts in and out, move the subwoofer closer to the bar, remove obvious obstructions and follow the manufacturer's pairing procedure. Do not place a Wi-Fi router directly on top of either component.

Keep the ventilation openings clear. A red or flashing status light may indicate a lost link, pairing problem or protection condition rather than a placement-related bass issue.

Placement in apartments

In an apartment, avoid placing the subwoofer against a shared wall or directly in a corner adjoining another residence. Bass energy travels through walls and floors far more readily than dialogue.

Isolation feet or a suitable platform can reduce mechanical vibration entering the floor, but they cannot eliminate airborne bass. Lower the subwoofer level, use Night mode and respect quiet hours.

Near-field placement beside or behind the sofa may allow satisfying impact at a lower level. Test carefully because close placement can be too strong for one listener.

Placement on timber floors

Timber floors can transmit vibration and create rattles. Make sure the subwoofer sits level and stable, with all feet contacting the floor.

A dense isolation pad can reduce cabinet vibration passing into lightweight flooring. It will not fix room modes or prevent deep sound travelling through the building structure.

Check nearby picture frames, doors, cabinet panels and loose objects before blaming the subwoofer itself for buzzing.

Placement on carpet

Carpet is generally fine if the subwoofer remains stable and any downward-facing driver or port receives the required clearance.

Use the supplied feet or suitable spikes only as instructed. A thick, soft pile can allow a tall narrow subwoofer to wobble, particularly around children or pets.

Placement in large open-plan rooms

A large connected lounge, dining and kitchen area contains far more air than the visible television zone. A small subwoofer may struggle regardless of where it is placed.

Begin near the front wall, test positions along that wall and consider near-field placement if output is insufficient. Avoid automatically turning the subwoofer to maximum, which can increase distortion without producing useful deep bass.

A more capable system may be necessary for very large rooms. Placement can maximise available performance but cannot manufacture output the hardware cannot produce.

Do soundbars and subwoofers need to match?

Soundbar subwoofers are normally proprietary. They use brand- and model-specific wireless pairing, processing and crossover settings.

You generally cannot pair a random powered subwoofer with a soundbar, even if both products support Bluetooth or Wi-Fi. Some premium ecosystems support one or two defined subwoofer models.

Confirm compatibility before purchasing a replacement or additional unit. A matching brand name is not enough.

Use room calibration after placement, if supported

Depending on the system, room calibration can adjust aspects of level, timing or frequency response. Samsung SpaceFit Sound, JBL calibration and Sonos Trueplay use different methods. Some adapt automatically; others require a guided procedure. The Sony HT-S400 has no automatic room-calibration function.

Place every component in its intended position first. For a guided calibration, keep the room quiet and follow the model’s microphone and listening-position instructions. For an automatic system, enable its room-adaptation feature as directed by the manual.

After moving the soundbar, subwoofer, rear speakers, sofa or major furniture, repeat guided calibration if available or allow the automatic system to adapt, following its instructions.

Set the subwoofer level after calibration

Use familiar dialogue, music and film scenes rather than a single bass-heavy demonstration. The subwoofer should add depth and scale without drawing constant attention to its location.

If every male voice sounds thick, reduce the subwoofer level or try another position. If films lack weight but the subwoofer is working, raise it gradually.

Do not immediately maximise bass enhancement. Strong room peaks can make the system sound impressive for five minutes and exhausting for an entire film.

Keep cables safe and accessible

Use HDMI eARC for the soundbar where available and leave enough room behind the connector. Route power and signal cables so they do not cross walkways or carry the weight of the equipment.

Do not run mains extension leads under rugs. Heat, crushing and unnoticed damage create a safety risk.

For wall-mounted installations and new power points, use appropriately licensed Australian tradespeople. Concealed wiring should be suitable for the installation and comply with local requirements.

Can you place the soundbar above a fireplace?

A fireplace installation can create heat, height and cable-routing problems. The television may already sit higher than comfortable, and adding the soundbar above or below it can push the audio even farther from seated ear level.

Heat and soot can damage electronics. Follow the fireplace manufacturer's minimum clearances and measure the surface temperature around the proposed position while the fireplace is operating normally. A mantel may redirect some heat, but it does not guarantee that the equipment is safe.

If the soundbar or television would exceed its permitted temperature or sit uncomfortably high, choose another wall. Appearance is not worth shortened equipment life or poor viewing ergonomics.

What if the soundbar blocks the TV stand?

Some televisions use wide feet that leave no room for a long soundbar, while others place a central stand exactly where the bar needs to sit. Measure the usable width and depth rather than relying only on the television's screen size.

A soundbar can sit in front of television feet if the furniture is deep enough and the bar remains stable. Do not rest it across the feet or allow it to overhang the cabinet.

A compatible pedestal stand or wall mount can free the required space. Confirm the stand's screen-size, weight and VESA limits before replacing the original support.

How to fix boomy bass before changing settings

If bass sounds thick or every note has the same heavy character, move the subwoofer away from the nearest corner or wall. Even a small change can alter room reinforcement.

Check whether a cabinet door, window, floorboard or decorative object is rattling. A room vibration can sound like distortion from the subwoofer even when the driver is operating normally.

After adjusting placement, update calibration if supported and return bass enhancement to a neutral setting. Reduce the subwoofer channel gradually only after the physical location has been tested.

How to fix weak bass before buying another system

Confirm the subwoofer is paired, powered and receiving bass-rich material. News, talk programs and some music tracks contain little deep bass and are poor tests.

Move the unit closer to a wall or corner in small steps, then listen from the sofa. If bass is strong elsewhere in the room but disappears at the main seat, the problem is likely a room cancellation rather than insufficient subwoofer power.

Moving the sofa forward or backward can sometimes improve bass more than moving the subwoofer. Once practical positions have been exhausted, update calibration if supported and adjust the subwoofer level.
