Our compact streaming choice

KEF LSX II LT

A compact active pair for streaming, computer audio and stereo TV sound. Choose it for the integrated digital system; choose passive speakers when separate components suit you better.

Our shortlist at a glance

These examples illustrate three buying routes, rather than a claim that one design always sounds best.

How we chose these options

We compared manufacturer specifications, Australian listings, connection options, included amplification and practical upgrade paths. These are research-led recommendations, not hands-on listening tests. We prioritised clear examples of the three architectures and the complete system cost, rather than comparing speaker-only prices with complete powered systems.

Compact active system

1. KEF LSX II LT

Our compact streaming choice when you want fewer separate components.

Fully activeHDMI ARCNetwork streaming

Model: LSX II LT — Graphite Grey (AU). Checked price: $1,695 per pair.

The LSX II LT combines dedicated driver amplification with network streaming and digital inputs. HDMI ARC serves a compatible television, while USB-C supports a computer. The primary speaker connects to mains power and supplies its partner through the dedicated interspeaker cable.

Choose it for a compact music, desktop or stereo TV system. It has no analogue line or phono input, so it is not a direct wired match for a conventional turntable. Its app-based room settings are not automatic microphone-based room correction.

Why choose it

• No separate power amplifier or network streamer needed.
• TV and computer connections in a compact pair.
• Subwoofer output for later expansion.

Reasons to reconsider

• No analogue line or phono input.
• The two speakers still need their dedicated connecting cable.
• Not a conventional expandable AV surround system.

Best for: A smaller living space or desk where streaming and digital sources matter most.

Lower-cost powered pair

2. Audio-Technica AT-SP3X

The simpler powered route for a desk or line-level music source.

Powered pairRCA line inputBluetooth

Model: AT-SP3X — black. Checked price: $449.99 per pair, plus delivery.

The AT-SP3X has amplification in its right speaker and a wired passive left partner. It accepts stereo RCA line-level audio or Bluetooth, so a separate power amplifier is unnecessary.

A turntable needs a built-in or external phono preamplifier before its RCA input. There is no HDMI ARC input, USB audio input or dedicated subwoofer output. It suits straightforward music playback better than a TV-first system needing one-remote control.

The linked Australian eBay listing is sold by Midland Records Perth. Compare its delivered price with local retailers before ordering.

Why choose it

• Amplification included at a lower total entry price.
• Simple wired analogue or Bluetooth connection.
• Compact cabinets for a modest setup.

Reasons to reconsider

• No HDMI ARC or USB audio.
• No dedicated subwoofer output.
• Powered architecture differs from a fully active driver-amplified design.

Best for: A buyer wanting basic music playback without building a separate amplifier system.

Passive upgrade route

3. KEF Q3 Meta

The passive option for a suitable existing amplifier or a system built in stages.

Passive speakersSeparate amp requiredComponent flexibility

Model: Q3 Meta — Satin White. Checked price: $1,300 per pair; amplifier extra.

The Q3 Meta is a passive bookshelf pair, so its purchase price does not include amplification, streaming or TV connectivity. Those functions come from the amplifier, receiver and sources you choose.

It makes more sense if you already own suitable electronics or want to change components separately. KEF specifies a 4-ohm nominal impedance with a 3.2-ohm minimum; choose an amplifier suited to that load and your listening level. Budget for speaker cable and suitable stands or furniture too.

Why choose it

• Amplifier and digital sources can be replaced independently.
• Can form part of a conventional receiver-based system.
• No speaker streaming platform to maintain.

Reasons to reconsider

• The complete system costs more than the speaker pair alone.
• Amplifier compatibility needs checking.
• Larger cabinets need appropriate space and support.

Best for: Someone with a suitable amplifier, or plans for a flexible component-based system.

Active vs passive speakers at a glance

What is a passive speaker?

A passive speaker has no built-in power amplifier. It receives an amplified signal through speaker cable from an integrated amplifier, stereo receiver, power amplifier or AV receiver.

Inside a typical two-way passive speaker, a passive crossover divides the high-power signal between the woofer and tweeter. The crossover uses components designed to handle the voltage and current coming from the amplifier.

The speaker itself does not normally need a wall outlet. Volume selection, source switching, streaming, digital conversion and room correction—where provided—take place in separate equipment.

Passive speaker advantages

• Large choice of speakers, amplifiers and system combinations.
• Amplifier and speakers can be upgraded independently.
• Easy to add a modern streamer without replacing the speakers.
• Well suited to AV receivers and multi-channel home theatre.
• Only speaker cables need to reach each speaker position.
• Passive designs can remain useful long after a streaming platform becomes obsolete.
• A fault in the amplifier does not automatically require replacing the speakers.

Passive speaker disadvantages

• Requires a compatible amplifier or receiver.
• More equipment, cables and shelf space.
• The buyer must understand impedance, sensitivity and amplifier capability.
• Total system cost may exceed the speaker price substantially.
• A poor amplifier or unsuitable room placement can limit performance.

What is an active speaker?

An active speaker system includes amplification within its cabinets. In a fully active design, an electronic crossover divides the low-level audio signal into frequency bands before amplification. Separate amplifier channels then drive the woofer and tweeter directly.

Genelec explains that a typical active two-way design uses one amplifier for the woofer and another for the tweeter. Because the manufacturer controls the drivers, amplification, crossover, protection and enclosure as one system, each section can be tuned specifically for its task.

Consumer active speakers may also contain digital signal processing, volume control, a DAC, streaming services, Bluetooth, HDMI ARC, optical inputs and room correction. Some pairs contain all electronics in one primary speaker, while others distribute amplification and processing between both cabinets.

Active speaker advantages

• Amplifiers and drivers are matched by the manufacturer.
• Fewer separate components and often less visible cabling.
• May include streaming, digital inputs, remote control and room adjustment.
• DSP can optimise crossover behaviour, bass and driver protection.
• Compact systems can deliver strong performance for their size.
• No need to research a separate power amplifier.

Active speaker disadvantages

• Electronics failure can remove an entire speaker or pair from service.
• Streaming and app features may age faster than the speaker drivers.
• Amplification cannot normally be replaced with a preferred model.
• One or both speakers need access to mains power.
• Proprietary wireless links or inter-speaker cables can restrict future use.
• Home theatre integration may require analogue pre-outs or brand-specific products.
• Large active speakers can be heavier and more difficult to service.

Powered does not always mean fully active

A powered speaker contains an amplifier, but the word does not reveal how the crossover and second speaker operate. One common affordable arrangement contains a stereo amplifier inside the right speaker. Speaker cable then carries an amplified signal to a conventional passive left speaker.

Audio-Technica describes one of its powered bookshelf pairs this way: the right speaker contains the amplifier and Bluetooth circuit, while the left speaker is passive. This remains convenient because no external amplifier is needed, but it is not the same architecture as a separately amplified active two-way monitor.

Before comparing specifications, ask:

• Does each speaker contain amplification?
• Does each driver have a dedicated amplifier channel?
• Is the crossover analogue passive, analogue active or DSP-based?
• How are the left and right speakers connected?
• Can either speaker operate if the primary unit fails?

Which design sounds better?

There is no general winner. Sound quality depends on the drivers, enclosure, crossover, amplification, distortion, directivity, room, placement and listening level.

Active design offers engineering advantages because the manufacturer controls the whole signal path. Driver-specific amplification and DSP can produce precise crossover integration, protection and bass extension from a compact cabinet.

Passive design gives the owner more combinations. This can produce an outstanding result when the amplifier and speakers are suitable, but it can also lead to expensive mismatches or upgrades that change very little.

Compare total system cost

The price tag on passive speakers is only one part of the system. Depending on what you already own, the complete cost can include:

• an integrated amplifier or AV receiver;
• a network streamer;
• a digital-to-analogue converter;
• a phono preamplifier;
• speaker cable and interconnects;
• stands or isolation products; and
• a remote-control or multi-room system.

An active system may combine most of these functions, making an apparently expensive pair competitive once the complete passive alternative is priced. However, an active product with redundant features is not good value. There is little benefit in paying for a premium streamer if you intend to use only an external analogue source.

Amplifier matching for passive speakers

Manufacturers commonly publish nominal impedance, sensitivity and recommended amplifier power for passive speakers. None of these figures should be considered alone.

Impedance

Impedance varies with frequency. A speaker labelled 8 ohms may fall much lower at certain frequencies. Confirm that the amplifier is designed to drive the speaker’s nominal and minimum impedance, particularly at high listening levels.

Sensitivity

Sensitivity indicates how loudly a speaker plays for a given input under the manufacturer’s test conditions. A less sensitive speaker generally needs more amplifier power to reach the same volume.

Power

A huge amplifier figure does not guarantee quality, and an amplifier that appears modest is not automatically unsafe. Damage can occur through excessive clean power or through a smaller amplifier driven into severe clipping.

Consider room size, listening distance, desired volume, speaker impedance and sensitivity. Ask the speaker manufacturer or an experienced retailer about compatibility when the specifications are unclear.

Active speakers for television sound

Active speakers can provide a wider stereo image and larger cabinets than many soundbars. For convenient TV use, look for:

• HDMI ARC or eARC;
• control through the TV remote using HDMI-CEC;
• automatic wake and standby;
• lip-sync adjustment;
• a centre-image or dialogue setting;
• a subwoofer output; and
• stable connection after firmware updates.

An optical connection can deliver reliable stereo audio but may not provide the same automatic power and volume control. Bluetooth is usually a poor primary TV connection because latency and reconnection behaviour can cause frustration.

Passive speakers for television and home theatre

Passive speakers are the conventional choice for a surround system. An AV receiver can power front, centre and surround channels, decode movie formats, manage bass and perform room correction.

You can begin with two speakers and add a centre channel, subwoofer and surrounds later. Check that a matching centre speaker remains available if dialogue clarity and consistent front sound are important.

Running several active speakers in home theatre is possible, but the processor needs suitable line-level pre-outs, every speaker needs power and cable management becomes more complicated. Some wireless ecosystems support surround expansion but restrict you to compatible products from that system.

Which is better for music streaming?

Active streaming speakers offer the neatest system: connect them to the network, choose music in an app and control volume without a separate amplifier. Check external inputs individually: some accept analogue and digital sources, while others, including the LSX II LT, omit analogue inputs.

The risk is software dependence. Streaming services, security requirements and operating systems change. Check whether the speakers can still accept ordinary analogue, optical, USB or HDMI signals if the manufacturer eventually stops updating the app.

With passive speakers, streaming depends on a separate streamer or streaming amplifier. That box can be replaced while the speakers remain unchanged.

Which is better for a turntable?

Either design can work, but a phono cartridge normally needs a phono preamplifier before connecting to a standard line input.

A turntable can feed active or powered speakers through an appropriate analogue connection when:

• the turntable has a built-in phono stage and is set to LINE; or
• the active speakers have a compatible PHONO input; or
• an external phono preamplifier sits between them.

A passive system requires an amplifier, which may already include a moving-magnet or moving-coil phono input. Check the exact cartridge compatibility rather than assuming any socket labelled PHONO will suit everything.

Do not send an active line-level output into a phono input, and do not connect a bare phono-level signal to a normal line input unless a phono stage is present.

Which is better for a desktop?

Active speakers usually win on a desk because they remove the need for a full-size amplifier. Useful desktop features include:

• USB audio from a computer;
• front or accessible volume control;
• headphone output;
• adjustable desktop EQ;
• balanced inputs for professional equipment;
• low idle noise at close distance; and
• compact stands or isolation pads.

Many studio monitors are active speakers designed for production rather than automatically for casual listening; passive studio monitors also exist. Some lack remote volume control, Bluetooth, digital inputs or consumer-friendly standby. Their balanced XLR or TRS inputs may require an audio interface or monitor controller.

Bass and subwoofer integration

Small active speakers can use DSP to extend bass at moderate levels, but physics still limits deep-bass output and maximum volume. Protection processing may reduce bass as volume rises.

Look for an active system with:

• a dedicated subwoofer output;
• adjustable crossover frequency;
• high-pass filtering for the main speakers;
• subwoofer level and phase controls; and
• room-correction support where useful.

A passive stereo amplifier may provide only a basic subwoofer output, while an AV receiver usually offers more complete bass management. Some traditional stereo amplifiers provide no sub output but can still work with a subwoofer offering speaker-level inputs.

Room correction and DSP

Active speakers increasingly include boundary controls, app-based EQ or automatic room correction. These tools can reduce excessive bass caused by nearby walls and improve consistency around the listening position.

They cannot fix every acoustic problem. Severe room reflections, poor placement and deep cancellation nulls require physical changes, speaker movement, listening-position adjustment or acoustic treatment.

Passive systems can also use DSP through a compatible amplifier, streamer or external processor. Keeping DSP outside the speaker allows the processing platform to change independently.

Placement matters more than the label

Either speaker type can sound poor when pushed into a cabinet or placed unevenly. Start with:

• the tweeters close to seated ear height;
• similar distance from the main listening position;
• enough clearance from rear and side walls;
• stable stands or furniture;
• some separation from turntables and vibrating surfaces; and
• the manufacturer’s recommended toe-in.

Do not assume bookshelf speakers belong inside a bookshelf. Rear ports and cabinet reflections can make that position unsuitable unless the design and controls accommodate it.

Cables and power requirements

Passive speakers need speaker cable from the amplifier. Sensible copper cable of an appropriate gauge and length is generally enough; expensive exotic cable should not replace good speakers, placement or room treatment.

Active speakers need audio or network connections and mains power. Some use one powered primary speaker plus a proprietary link to the second. Others require a power outlet and signal cable at each cabinet.

Plan the room before buying. A beautiful active system becomes less attractive if extension leads cross doorways or the only outlets sit in the wrong corners.

Wireless active speakers are not completely wireless

“Wireless” normally refers to the music signal or communication between components. The speakers still require power, and some pairs use a cable between left and right cabinets.

Check:

• whether both speakers need wall power;
• whether the stereo link is wired or wireless;
• maximum permitted distance between speakers;
• whether high-resolution playback changes when wireless;
• what happens during network outages; and
• whether analogue inputs remain usable without an account.

Upgrades and long-term ownership

Passive systems offer the clearest upgrade path. You can change the amplifier, add streaming, replace the DAC or move the speakers into another room. A well-built passive speaker can outlive several generations of digital electronics.

An active system is a more integrated appliance. The matching is an advantage on the day of purchase but can become a limitation if the app, wireless module or amplifier fails years later.

Before buying active speakers, investigate:

• software update history;
• parts and service availability in Australia;
• warranty coverage for amplifiers and drivers;
• whether streaming accounts are compulsory;
• operation without internet access;
• replaceability of the primary speaker or electronics module; and
• whether a failed secondary speaker can be serviced separately.

Which system is easier to repair?

A passive speaker has relatively few components: drivers, crossover, terminals and cabinet. A separate amplifier contains the active electronics. If one fails, the other can continue to be used or tested independently.

Active speakers combine several systems. A failure in a power supply, DSP board, wireless module or amplifier can silence the speaker even when its drivers remain healthy. Repair may require proprietary parts and authorised service.

This does not mean active speakers are unreliable. Factory protection and matched amplification can reduce driver abuse. The long-term question is whether specialist parts and software support will remain available.

Who should buy active speakers?

Active speakers are more likely to suit you if:

• you want a clean system with fewer boxes;
• you primarily stream music;
• you need speakers for a desk or small room;
• you want HDMI or optical TV sound without an AV receiver;
• you do not enjoy matching amplifiers and speakers;
• you value integrated room adjustment or DSP; and
• you are comfortable treating the speaker pair as one complete product.

Who should buy passive speakers?

Passive speakers are more likely to suit you if:

• you already own a suitable amplifier;
• you want to upgrade one component at a time;
• you are building a multi-channel home theatre;
• you expect to keep the speakers for many years;
• you want maximum amplifier and source choice;
• you prefer simpler speaker construction; or
• power outlets are unavailable near both speaker positions.

What to check before buying

• Complete system cost: include amplification, streaming, stands, cables and subwoofer needs.
• Room size: small speakers may struggle at distance or high volume.
• Connections: confirm every present and likely future source.
• TV compatibility: check HDMI ARC, remote control and lip-sync behaviour.
• Turntable compatibility: identify where the phono preamplifier will sit.
• Subwoofer integration: look beyond the presence of a socket to actual bass-management controls.
• Power access: active speakers may need outlets at both positions.
• App dependence: check offline operation and update history.
• Home theatre plans: decide before investing in a closed stereo ecosystem.
• Australian support: consider warranty, service centres and parts availability.

Frequently asked questions

Do active speakers need an amplifier?

They contain amplification, so they do not need a separate power amplifier. They may still need a preamplifier, controller or source depending on their inputs and volume controls.

Can passive speakers connect directly to a TV?

No. They require an amplifier or AV receiver between the TV and speakers. The amplifier must accept a compatible TV output such as HDMI ARC or optical.

Can I use active speakers with an amplifier?

Only through a suitable line-level or preamplifier output. Never connect an amplifier’s powered speaker terminals to an ordinary active speaker’s line input unless the manufacturer expressly provides a compatible speaker-level input.

Are active speakers better for bass?

DSP and matched amplification can help an active speaker produce impressive bass for its size, but cabinet volume and driver displacement still set limits. A subwoofer may be needed for deep bass and high volume.

Are studio monitors good for normal music listening?

They can be excellent, but may lack consumer conveniences such as remote volume, streaming, HDMI and automatic source switching. They can also expose poor recordings and room problems clearly.

Do passive speakers last longer?

They can remain technologically relevant longer because they contain no streaming platform or amplifier. Physical durability still depends on driver surrounds, crossover components, cabinet condition and treatment.

Can active speakers be used for surround sound?

Yes, but the processor needs suitable outputs and each active speaker needs power. A conventional AV receiver and passive speakers are usually simpler for a flexible multi-channel system.
