KEF LS LUXE Wireless Speaker Review – Why This Compact All-in-One HiFi System Currently Sets the Benchmark

Two compact loudspeakers should not create this degree of scale, bass authority and spatial ease. That contradiction defines the KEF LS LUXE more accurately than its position between the KEF LS50 Wireless II and KEF LS60 Wireless. It is a complete stereo All-in-One HiFi system, requiring neither an external amplifier nor a separate streamer, yet it does not behave like a convenient alternative to serious HiFi. It behaves like serious HiFi. Ross Lovegrove’s sculptural enclosure makes the system impossible to mistake for a traditional pair of loudspeakers, while KEF’s engineering explains why the distinctive form is more than decoration. Inside are a newly developed 16.5 cm Uni-Q driver, VECO velocity feedback, current-controlled amplifier stages, MAT and 760 watts of total system power. The KEF W2 Wireless platform adds streaming services, network playback, HDMI eARC and the connections required for external sources. What emerges is not simply a more powerful compact wireless speaker, but a system whose individual elements operate with unusual coherence. In its class, the KEF LS LUXE currently sets the benchmark.

The Scale Is the First Surprise – the Control Is the Lasting Impression

The opening minutes with the KEF LS LUXE are slightly disorientating. Its physical size prepares the listener for a polished compact system. What arrives instead is a broad, firmly organised stereo image with low-frequency extension more readily associated with substantially larger loudspeakers.

KEF has not created that impression by exaggerating the presence range or adding a conspicuous rise in the upper bass. There is no deliberately sharpened detail and no blanket of warmth placed beneath every recording. The tonal balance is initially so natural that the scale of the performance takes a moment to register.

Voices have substance without becoming thick. Instruments occupy stable positions rather than drifting as an arrangement grows denser. Bass extends far below what the cabinet dimensions imply, but it remains integrated with the rest of the spectrum. The LS LUXE does not continually remind the listener how much bass it can produce.

The system’s ability to preserve credible proportions is especially important. A vocalist does not grow beyond natural dimensions merely because the chorus becomes more forceful. A double bass gains weight and volume while its strings, body and decay remain clearly related to one instrument.

Many compact loudspeakers can sound large for a few moments. The KEF LS LUXE sustains that scale without allowing the presentation to lose focus or internal order.

A Point Source with Much Greater Responsibilities

At the centre of each loudspeaker is a 16.5 cm 12th-generation KEF Uni-Q driver developed specifically for the LS LUXE. It combines an aluminium bass/midrange cone with a vented 25 mm aluminium tweeter positioned at its acoustic centre.

That coaxial arrangement allows the two frequency ranges to radiate from substantially the same point. Instead of compensating for the physical separation between conventional bass/midrange and treble drivers, KEF can align their timing and dispersion within a single assembly.

In this system, however, the Uni-Q driver carries an unusually broad responsibility. There is no separate woofer to take over the deep bass. The same driver must provide the low-frequency foundation, cover the midrange and hand over cleanly to the centrally mounted tweeter.

Its larger diameter gives it more effective diaphragm area than the driver used in the KEF LS50 Wireless II. Greater radiating area allows more air to be displaced, while the larger enclosure and new control system enable the LS LUXE to use that capacity more effectively.

KEF’s comparative measurements show approximately 8 to 10 dB more acoustic output below 40 Hz than the KEF LS50 Wireless II at matched levels, depending on frequency. The significance lies not only in the higher output, but in achieving it without a similarly large increase in distortion.

VECO Starts Where Conventional Amplification Stops

The low-frequency performance cannot be explained by driver size and amplifier power alone. Its most important technical foundation is KEF Velocity Control Technology, abbreviated to VECO.

KEF originally developed the technology for the KEF XIO soundbar. In the LS LUXE, it is used for the first time in a bass reflex loudspeaker.

A conventional amplifier regulates the voltage at the loudspeaker terminals. The current that actually flows through the voice coil depends on its impedance, and that impedance does not remain constant. It varies with frequency, temperature, voice-coil position and the magnetic conditions inside the driver motor.

Current is the quantity that generates the force responsible for moving the diaphragm. A current-controlled amplifier therefore acts more directly on the physical process and can reduce current-dependent distortion as well as thermal compression.

That approach creates another problem. The electrical damping normally provided by the voice coil’s back electromotive force is largely lost. Around its mechanical resonance, the diaphragm could move more than intended. A bass reflex design adds the resonant behaviour of the port to that of the driver and enclosure.

VECO gives the amplifier information about what happens after the electrical signal has been delivered.

The Amplifier Receives a Report from the Voice Coil

A passive sensor coil measures the velocity of the voice coil in real time. Its signal is returned to the amplifier with almost negligible delay and compared with the intended movement. Any deviation can be corrected immediately.

The control loop therefore extends beyond the amplifier output. It includes the mechanical behaviour of the driver under the actual operating conditions.

Constructing the sensor without allowing it merely to pick up the electrical drive signal required a complex solution. Its conductor runs in four counter-wound loops across both sides of a flexible circuit board and has a total length of approximately 55 m. Eight small neodymium magnets and two steel rings form the corresponding magnetic system.

The geometry prevents the sensor coil from acting like the secondary winding of a transformer coupled to the main voice coil. It measures movement rather than simply reproducing the amplifier signal. According to KEF, the sensor output tracks diaphragm velocity with considerable accuracy up to approximately 400 Hz.

Using VECO in a bass reflex design also requires the feedback bandwidth and gain to account for the interaction between driver and port around their respective resonances. The intention is not to produce as much bass as possible at any cost, but to keep the system under control as the diaphragm excursion and listening level increase.

That objective is clearly audible. Notes reach deeply and stop cleanly. Bass lines retain their shape, and high playback levels do not turn the low end into a broad, slowly decaying mass.

KEF’s measurements indicate reductions in harmonic distortion of between 6 and 14 dB through the bass and midrange compared with the KEF LS50 Wireless II, depending on frequency. With a demanding multitone signal, numerous distortion products in the midrange are reduced by between 10 and 20 dB.

These measurements do not describe timbre or musical expression. They do, however, provide a persuasive explanation for the way the LS LUXE keeps complex arrangements intelligible when many compact systems begin to sound compressed or confused.

MAT Controls What Happens Behind the Tweeter

The 25 mm aluminium tweeter is backed by KEF’s Metamaterial Absorption Technology. MAT employs a labyrinth-like structure in which different frequency components of the rearward energy are directed into appropriately dimensioned channels.

KEF states that the structure absorbs 99 per cent of this unwanted sound. The tweeter therefore has to contend with substantially less energy returning from its rear chamber and interfering with its forward output.

Fine spatial information, cymbals and voices benefit through reduced overlay rather than through artificially boosted treble. Resolution is high, but the LS LUXE does not use brightness as a substitute for detail.

MAT also has a second function in this particular system. The strong acoustic damping reduces the Q of the tweeter resonance. That allows KEF to use a current-controlled amplifier stage for the high-frequency section without allowing the resonance to become uncontrolled.

VECO feedback itself is applied only to the bass/midrange driver. In the treble, control is established through the combination of MAT, the tweeter and its specifically matched amplifier.

760 Watts Are Useful Because KEF Controls Where They Go

Each loudspeaker contains a 280 watt Class D amplifier for the bass/midrange and a 100 watt Class A/B amplifier for the tweeter. Across the stereo pair, total amplifier power is 760 watts.

The number confirms that there is substantial headroom for equalisation, dynamic peaks and high playback levels. More important is the active architecture surrounding it.

No passive crossover sits between amplifier and driver. Each section of the Uni-Q assembly is connected directly to its own amplifier, allowing KEF to develop the electronics around known driver behaviour rather than the uncertain characteristics of an external loudspeaker load.

The KEF Music Integrity Engine manages frequency division, phase and amplitude correction, protection functions and the way the system adapts at different volume levels. A FIR filter calculated specifically for the LS LUXE improves the timing relationship between the two frequency bands and reduces energy persisting after the main impulse.

Transients are therefore presented with precision, but without the artificial sharpness sometimes used to create an immediate impression of speed.

The value of this integration is practical as well as technical. The owner does not need to select an amplifier, calculate power requirements or search for a complementary combination of electronics, loudspeaker cables and passive speakers. KEF knows the electrical, mechanical and acoustic parameters of every relevant part of the signal path and can tune them as one system.

That convenience would have little value if the result merely sounded pleasant and unobjectionable. In the LS LUXE, the integrated approach produces a level of control that would be difficult to recreate with separate electronics and passive loudspeakers of comparable size and price.

Preventing Mechanical Energy from Becoming Sound

Electrical control is only part of the task. A powerful 16.5 cm driver also produces substantial reaction forces. If those forces pass directly through the driver basket into the front baffle, the enclosure can begin to vibrate and add delayed energy of its own.

KEF uses a Flexible Decoupling Chassis to isolate the Uni-Q assembly mechanically from the surrounding cabinet. The driver is connected through a carefully tuned flexible structure and damping material intended to minimise energy transfer without sacrificing mechanical stability.

The principle first appeared in the KEF LS60 Wireless, but it had to be recalculated for the larger and heavier two-way Uni-Q assembly used here. Finite-element simulations helped KEF distribute forces more evenly and avoid concentrated stress points.

This technology does not announce itself through one obvious sonic signature. Its contribution is reflected in the cleanliness with which the sound separates from the enclosures, the absence of a recognisable cabinet character and the way the presentation avoids developing an indistinct lower-midrange veil at higher levels.

Such mechanical discipline matters in any loudspeaker. It becomes particularly significant when the enclosure also contains amplifiers and power supplies.

The Cabinet Provides More Space than Its Dimensions Suggest

KEF could not have produced the LS LUXE enclosure efficiently from a conventional wood-based material. Its complex geometry is moulded from a specially formulated, glass-fibre-reinforced BMC composite.

BMC stands for Bulk Moulded Compound. The material can be formed precisely, provides considerable rigidity and requires less internal bracing than a traditionally assembled enclosure.

Reducing the amount of bracing releases more internal space for acoustic use. KEF’s engineers state that the LS LUXE provides approximately 50 per cent more internal volume than the KEF LS50 Wireless II, despite external dimensions of only 336 × 223 × 298 mm per speaker.

The rear panel combines thermal management and acoustic loading. A large aluminium heat sink dissipates heat from the electronics mounted directly behind it. Between the fins sits the rounded outlet of the bass reflex port.

The port’s flexible walls can yield slightly in a controlled way. This is intended to suppress resonances that could otherwise become audible as colouration or airflow noise at high levels. Enclosure structure, cooling and bass tuning are therefore treated as parts of the same physical design.

Ross Lovegrove’s Shape Is Part of the Engineering

Ross Lovegrove previously worked with KEF on the KEF Muon, KEF Muo, KEF Mu3 and KEF Mu7. With the LS LUXE, his contribution is not limited to covering established engineering in a decorative outer shell.

The front, sides and top flow into one another with few abrupt transitions. At the rear, the cooling fins and bass reflex opening continue the same organic visual language. Even the technically necessary elements appear to belong to the original form.

This shape also reduces hard edges around the Uni-Q driver. Visible fixings, decorative rings and sharp cabinet transitions have been avoided so that the radiated wavefront can move away from the baffle with less disturbance.

Lower diffraction contributes to a smoother response, but its influence away from the main listening axis is equally relevant. A more consistent off-axis spectral balance helps the direct sound and the energy reflected by the room remain better matched. The result is a broad stereo image that does not collapse as soon as the listener moves away from a precisely defined central seat.

Visually, the system makes no attempt to disappear. Eclipse Black appears technical and almost monolithic. Mineral White emphasises the soft surfaces. Dusk Titanium combines a warm metallic impression with the sculptural cabinet form.

Our Dusk Titanium review pair attracted attention even when it was not playing. That presence will polarise, but neutrality was clearly never the design objective.

Not a Compromise between the LS50 Wireless II and LS60 Wireless

The official position within the KEF LS Wireless Collection places the LS LUXE above the KEF LS50 Wireless II and below the KEF LS60 Wireless. That hierarchy describes price and range position, but it does not fully explain the model.

The LS LUXE is intended for listeners who appreciate the compact concept of the LS50 Wireless II but want deeper bass, greater dynamic reserves and a larger, more effortless spatial presentation. At the same time, it remains substantially smaller than the floorstanding LS60 Wireless.

Its two-way architecture also separates it technically from both obvious comparisons. It is not an LS50 Wireless II with a more elaborate cabinet, nor is it an LS60 Wireless with its lower section removed.

A single Uni-Q assembly in each channel must cover the complete range from deep bass to treble. VECO, current-controlled amplification, the larger internal volume, Flexible Decoupling Chassis and the dedicated DSP tuning were developed around that particular requirement.

The LS LUXE is consequently best understood as KEF’s most ambitious compact two-way Active Wireless Speaker rather than as a transitional product created simply to fill a space in the catalogue.

From Advanced Engineering to an Uncomplicated Daily Routine

The technical complexity disappears quickly once the system is installed. During the review, the KEF Connect app detected the speakers, established the network connection, assigned the channels and guided us through the basic room settings without unnecessary detours.

Afterwards, Qobuz Connect through an Apple iPhone 14 Pro worked as expected: select the KEF LS LUXE, choose the music and control the volume. Audirvāna Studio 3.3.3 integrated the system just as easily into a more library-oriented playback arrangement.

Volume adjustment is sufficiently fine for late-night listening. It is possible to reach the point at which the sound remains tonally complete and intelligible while the overall level stays neighbour-friendly.

The LS LUXE does not lose its balance when played quietly. Voices retain body, fine structures remain understandable and the bass foundation does not disappear. Increasing the level does not produce an abrupt tonal shift. Bass, midrange and treble rise together, while voices remain clear and the stereo image stays firmly organised.

This consistency makes the system easy to live with. Its technology is available when adjustments are required, but it does not impose itself during normal listening.

Wireless Communication with a Proprietary Approach

The two loudspeakers can exchange audio signals wirelessly. KEF bases this connection on WiSA, but does not use the standardised implementation unchanged. Its engineers employ a proprietary interpretation of the platform.

With the wireless inter-speaker connection, all sources are transmitted as Linear PCM at 24 Bit and 96 kHz. Connecting the speakers by Ethernet increases the internal rate to 24 Bit and 192 kHz.

Via the network, the system accepts Linear PCM signals at up to 24 Bit and 384 kHz as well as DSD. The maximum source resolution and the resolution of the wireless connection between the speakers are therefore separate specifications. For normal wireless operation, each speaker requires mains power, while the system itself needs access to the network.

Streaming without Locking the Listener into One App

The KEF W2 Wireless platform includes Qobuz Connect, TIDAL Connect and Spotify Connect. These services can therefore hand playback directly to the speakers from their respective apps.

Apple AirPlay, Google Cast and UPnP provide further network routes. Internet Radio and podcasts are integrated, alongside Amazon Music, Deezer and QQ Music through QPlay. Individual service availability depends on the country.

Bluetooth 5.3 is available for quick direct connections from mobile devices. Roon Ready certification has been announced but, according to the available product information, is not expected until 2027. This breadth allows the LS LUXE to fit into different listening habits without making the KEF Connect app the only route to music.

External Sources Are Not an Afterthought

The primary loudspeaker provides HDMI eARC, TOSLINK, coaxial S/PDIF and an analogue 3.5 mm stereo mini-jack. Ethernet serves both network access and the optional wired connection between the speakers.

A television, CD player, separate streamer, games console or analogue source can therefore become part of the same system. The USB Type C connection on the primary speaker is exclusively a charging output rated at a maximum of 5 V and 2 A. It is not an audio input.

Each speaker also has its own RCA subwoofer output. The system can consequently be expanded with one or two subwoofers. KEF has not included a phono stage. Given the otherwise comprehensive All-in-One specification, that omission is worth noting, but the decision is understandable. Many current record players already include a phono stage, while more ambitious vinyl listeners are likely to choose a separate solution suited to their cartridge.

A basic phono circuit added merely to complete the feature list would offer limited value to either group.

HDMI eARC Makes the LS LUXE More than a Music System

Connecting a television through HDMI eARC turns the KEF LS LUXE into a serious stereo alternative to a soundbar. Dialogue forms a clearly defined centre image despite the absence of a physical centre speaker. The soundstage extends beyond the screen, while film music retains the dynamic and spatial differentiation expected from a proper stereo system.

There are no discrete surround channels. In return, the complete frontal presentation sounds substantially larger, more credible and more musically convincing than that of typical compact soundbars designed primarily for immediate effects.

The LS LUXE therefore works not only as the main music system in a living room, but also as the audio solution for television, films and games.

Room Adjustment without Unnecessary Complexity

The KEF Connect app combines straightforward daily operation with meaningful control over placement and room interaction. Normal mode requires only basic information about room size and loudspeaker position. Expert mode opens further adjustments for bass extension, near-wall placement, reflective surfaces beneath the speakers and the acoustic damping of the room.

Bass extension can be set to More, Normal or Less. Desk Mode compensates for a large reflective surface below the speaker, while Treble Trim provides adjustment of up to 3 dB in either direction. Dedicated presets simplify the time and level alignment of various KEF subwoofers.

These options do not replace correct placement, nor do they attempt to function as a collection of decorative sound effects. They are focused on helping the LS LUXE operate correctly under different domestic conditions.

For everyday control without a smartphone, KEF supplies the C3 infrared remote control. It has an aluminium upper surface, backlit buttons and a programmable favourite key.

Placement Still Matters

Calling the KEF LS LUXE a compact loudspeaker should not be taken as an invitation to place it casually inside a shelf. The system generates sufficient bass energy to excite a large, resonant item of furniture.

If the supporting surface begins to vibrate, the resulting energy can blur the precision created by the loudspeaker itself. Effective mechanical isolation is therefore essential when the system is used on a lowboard or similar piece of furniture.

The optional KEF S-LUXE Floor Stand is our preferred solution. Its height of 628 mm positions the Uni-Q driver at a practical listening level, while an integrated fixing system secures the loudspeaker. Internal cable routing keeps the installation tidy.

Each stand weighs 6.8 kg and can be filled with inert material. Spikes and matching spike discs are included, allowing a stable installation without placing bare spikes directly on a sensitive wooden floor. The Slate Grey aluminium top plate follows the shape of the speaker base.

Some space behind the loudspeaker is advisable. The app can compensate for the tonal effect of near-wall placement, but it cannot prevent a resonant supporting surface from moving.

Strong toe-in is unnecessary because of the system’s even dispersion. In our room, an almost parallel arrangement with only a slight inward angle produced a broad soundstage and a comfortably large listening area.

A dedicated wall bracket would nevertheless have been a useful additional placement option.

Test Environment

Qobuz Connect was used with an Apple iPhone 14 Pro. Audirvāna Studio 3.3.3 provided an additional network playback route focused on music-library use. A Musical Fidelity M3scd served as the source for optical discs and was connected with a Wireworld Series 10 signal cable.

The speakers were powered with Wireworld Series 10 mains cables through a KECES IQRP-1500 Isolated Quantum Resonance Power Conditioner.

Consistent across Very Different Recordings

The KEF LS LUXE does not require a carefully selected playlist to make its case. Its strengths remain apparent across voices, electronic productions, sparse acoustic arrangements and densely produced pop and rock recordings.

It has no obvious favourite part of the spectrum. Resolution is high without creating nervousness, and the treble remains informative without being pushed forward. The bass is exceptional for a system of this size, but rarely distracts from the music by drawing attention to itself.

The essential quality is coherence. Scale, tonal balance, timing and spatial precision appear to belong to the same system rather than competing for attention.

That remains true as the volume changes. At low levels, the presentation stays complete. At higher levels, complex arrangements remain organised and voices are not overwhelmed by increasing bass energy.

Adele – Set Fire to the Rain

Set Fire to the Rain from the album 21 is densely produced and can quickly sound harsh and compressed on systems with a more forward-focused sound signature. The KEF LS LUXE powerfully places Adele’s voice in the center, yet keeps it cleanly separated from the expansive strings, the drums, and the numerous layered production tracks. The energy increases significantly in the chorus without the treble becoming shrill or the soundstage collapsing. The dynamic composure is particularly impressive: the speakers convey the grand gestures of the recording without sounding strained themselves.

Amanda McBroom – The Rose

The Rose from the album Dreaming largely reduces the resources to voice, piano, and space. This leaves little room for tonal imperfections to hide. Amanda McBroom’s voice sounds full-bodied and at a believable high register; breath and articulation are clearly discernible but not presented as isolated details. The piano has weight in the lower registers and a clean attack, without disintegrating into two separate realms of fundamental and overtones. Here, the KEF LS LUXE demonstrates perhaps its most important quality: it resolves details with fine detail without dissecting the music.

Ane Brun – The Opening

In “The Opening” from the album Rarities, the effect is achieved through subtle dynamic shifts, atmosphere, and a voice that oscillates between intimacy and spatial distance. The KEF LS LUXE creates a soundstage extending far beyond the outer edges of the cabinet and maintains a stable image even when moving away from the central listening position. Subtle textures in the background are preserved without being obtrusively emphasized. The recording gains depth, not just width; a genuine sense of separation emerges between the foreground vocals and the background soundscapes.

Diego el Cigala and Bebo Valdés – Lágrimas Negras

Lágrimas Negras from the album Bebo & Cigala puts timing and tonal accuracy to the test. Bebo Valdés’ piano has to be percussive yet harmonically complete, while Diego el Cigala’s voice remains raw, emotional, and at times almost brittle. The KEF LS LUXE doesn’t smooth over these contrasts. Attacks are precise, the rhythmic foundation has a springy energy, and the voice retains its characteristic texture. Despite this, the interplay never disintegrates into spectacular individual effects. It is precisely this cohesion that makes the performance so captivating.

Chris Rea – The Road to Hell Part I & II

“The Road to Hell,” from the album of the same name, begins atmospherically and then builds into a heavy, steadily driving arrangement. Here, the KEF LS LUXE demonstrates why VECO and the larger cabinet are far more than just a theoretical exercise. The deep pulse reaches surprisingly low, remains clearly defined, and propels the song forward with force without overwhelming the room with a long bass trail. Chris Rea’s distinctive voice stands firmly above the foundation, while the guitars and drums retain their definition. Even at higher volume levels, the soundstage remains open. The KEF LS LUXE doesn’t sound like a small speaker bravely overachieving, but simply like a superbly proportioned system.

Depeche Mode – Precious

“Precious” from the album Playing the Angel combines a precise electronic pulse with densely layered synthesizers and Dave Gahan’s unmistakable voice. Many compact systems deliver either punch or clarity in this context. The KEF LS LUXE manages both. Bass impulses begin and end precisely, the synthesized textures remain distinct, and the vocals are clearly centered. The song gains a physical presence without the subtle rhythmic shifts being lost under a blanket of bass.

Lee Marvin – Wand’rin Star

“Lee Marvin’s Wand’rin Star” from Paint Your Wagon is a fantastic example of how perfectly film scores were mixed by the major Hollywood studios in the 1960s. The piece thrives on a voice whose depth can quickly become caricature if a loudspeaker overemphasizes the upper bass. The KEF LS LUXE lends it enormous weight, yet allows consonants, chest resonance, and the space around the singer to remain clearly distinguishable. The orchestra spreads generously behind, instead of shrinking into a decorative accompaniment. This recording, in particular, demonstrates that genuine depth should not be confused with artificial warmth. The KEF LS LUXE reaches down to the lowest frequencies while maintaining tonal clarity.

Kari Bremnes – Sangen om fyret ved Tornehamn

Sangen om fyret ved Tornehamn from the album Svarta Björn summarizes many of the strengths of the KEF LS LUXE. Kari Bremnes stands tangible and calm in the room, the deep foundation has authority, and the sparse instrumentation opens up a wide, dark stage. Small changes in the reverberation are easy to understand without the loudspeakers diverting your attention from the narrative to the recording technology. The system combines Nordic clarity with substance and shows that neutrality does not have to mean emotional distance.

Does the KEF LS LUXE Need a Subwoofer?

For music playback in an average-sized living room, the answer will usually be no. Depending on the selected EQ setting, the KEF LS LUXE extends to 35 Hz at -6 dB. More important than the figure is the control with which it reproduces that region. Bass lines have foundation, large drums develop convincing pressure and electronic productions do not appear incomplete.

A subwoofer remains appropriate in very large rooms, for home cinema material requiring full low-frequency effects or when the main loudspeakers are to be relieved of the deepest frequencies.

With a separate subwoofer output on each speaker and suitable presets in the KEF Connect app, the LS LUXE provides an unusually convenient basis for integrating either one or two subwoofers. The optional KEF KW1 Wireless Subwoofer Adapter also allows more flexible placement without a long signal cable.

FAQ about the KEF LS LUXE

Price & Availability

The KEF LS LUXE is available in Eclipse Black, Dusk Titanium and Mineral White at a recommended retail price of € 4.000,- for the stereo system.

The package includes both loudspeakers, mains cables, an inter-speaker cable, an HDMI cable, the KEF C3 infrared remote control with batteries and the necessary documentation. The system is available through authorised retailers and directly from KEF.

The KEF S-LUXE Floor Stands, the 8 m KEF K-Stream inter-speaker cable and the KEF KW1 Wireless Subwoofer Adapter are sold separately.

Getting to the point

The most revealing aspect of the KEF LS LUXE is how quickly its individual technologies cease to feel like individual technologies. VECO, MAT, current-controlled amplification, mechanical decoupling, DSP and the moulded composite enclosure are all significant, but none dominates the listening experience.

What remains is a compact system that sounds remarkably complete. Its bass reaches deeply and retains definition. Voices have body without excessive warmth. Treble detail is presented cleanly rather than highlighted. The soundstage extends well beyond the enclosures and remains stable across a usefully broad listening area.

The LS LUXE also retains this balance under very different conditions. It sounds convincing at restrained late-night levels and remains organised when asked to play loudly. It can fill an average-sized living room without creating the impression that a compact loudspeaker is being driven beyond its natural limits.

There are larger loudspeakers, more powerful systems and combinations with additional subwoofers that can offer still greater reserves. That does not diminish what KEF has achieved within the size, price and intended application of the LS LUXE. At no point does it feel like a lifestyle system whose convenience must be weighed against obvious sonic concessions.

Its form will divide opinion. Ross Lovegrove’s design has too much personality to disappear unnoticed, but the shape has acoustic purpose and the finish supports the product’s positioning. We would use the LS LUXE with the optional S-LUXE Floor Stands whenever possible. A matching wall bracket would have made the placement options more complete.

As an All-in-One HiFi system, the functional specification leaves little unresolved. Streaming, Bluetooth, HDMI eARC, digital and analogue sources, two subwoofer outputs and a well-designed app allow the speakers to replace a conventional chain of separate components. The absence of an integrated phono stage is defensible, although the expected wait for Roon Ready status until 2027 will matter to existing Roon users.

At the KEF Music Gallery London, we had the opportunity to discuss the LS LUXE in detail with one of its developers in a small-group setting. The conversation covered VECO, current control, MAT, mechanical isolation and the relationship between the driver and enclosure.

Every part of the engineering provides a logical explanation for the performance. Yet hearing the system still produces an element of disbelief. The authority, spatial scale and composure emerging from two enclosures of this size remain extraordinary even when the mechanisms behind them are understood.

KEF demonstrates how a premium audio system can be compact, visually integrated into a modern living space and simple to operate without reducing sound quality to a secondary feature. The KEF LS LUXE is currently the best compact Active Wireless Speaker system we have heard in this class. It is the new benchmark, and our recommendation is unequivocal.
