Cambridge Audio L/R Series: the brand's first active wireless speakers take direct aim at KEF

Cambridge Audio enters the active wireless arena

There are moments in this industry when a brand does something that genuinely redraws the competitive map. Cambridge Audio's debut at CES in January 2026 was one of them. After more than five decades as a maker of amplifiers, CD players, streamers and DACs — consistently brilliant separates and all-in-ones, but always the sort of kit you pair with a passive speaker — the Cambridge Audio L/R Series marks the company's first foray into active, wireless loudspeakers. It's a significant pivot, and on paper at least, it's an impressive one.

The L/R Series spans three models: the entry-level L/R S at AU$549 per pair, the mid-tier L/R M at AU$1,599 per pair, and the flagship L/R X at AU$2,299 per pair. The launch is staggered across 2026, so we won't have all three in Australian stores simultaneously, but the range is already generating serious conversation in enthusiast circles — and for good reason. When you look at the spec sheet for the L/R X in particular, you quickly understand who Cambridge Audio is gunning for.

Why this matters for Australian buyers

The active wireless speaker category has matured enormously over the past five years. What once felt like a compromise — an all-in-one convenience play that sacrificed resolution and dynamics — has evolved into a genuinely compelling alternative to separates. KEF, with its LS50 Wireless II and the later LSX II, essentially defined the category for discerning listeners. Sonos approached it from the mass-market end. Devialet carved out its own extremely expensive niche with the Phantom line. But the sweet spot — audiophile-grade performance, real-world connectivity, sensible WAF-friendly aesthetics, and a price that doesn't require a second mortgage — has remained frustratingly crowded with near-misses.

Cambridge Audio's entry is notable precisely because the brand understands the separates buyer. These are speakers designed by people who know what a StreamMagic platform is supposed to do, what an MM phono stage should sound like, and why HDMI eARC matters for a listener who wants their speakers to serve double duty as a TV system. That insider knowledge, if it translates faithfully into the L/R Series, could make these genuinely dangerous competitors.

In the Australian market specifically, the pricing is competitive. The L/R X at $2,299 per pair sits in the same conversation as the KEF LS50 Meta (check price) when you factor in what you'd spend on a matching streamer-amplifier to drive those passive speakers. The value proposition isn't just about the speakers themselves — it's about what you don't have to buy separately.

The flagship L/R X: specifications worth examining

Let's spend some time with the L/R X, because the engineering decisions here reveal a lot about Cambridge Audio's intent. The total amplification on board is 800 watts — a genuinely substantial figure for a standmount-sized active speaker. That power budget funds a 2.5-way driver configuration comprising a 28mm Torus tweeter, dual five-inch woofers, and — this is the detail that caught my attention — dual six-inch force-cancelling passive radiators.

Force-cancelling passive radiators are not a gimmick. When two passive radiators are mounted in opposition, their mechanical motion cancels out the reactive forces that would otherwise cause cabinet vibration and colouration. It's an approach that acknowledges the fundamental tension in designing a compact, high-output enclosure: you want extended bass response, but you don't want the cabinet itself becoming a resonator. The decision to employ this topology in a speaker at this price point tells me that Cambridge Audio's acoustic engineering team has thought carefully about what goes wrong with competitors at similar price points, and tried to address it structurally rather than through DSP correction alone.

The Torus tweeter designation is worth noting too. Cambridge Audio has used the Torus name before in its speaker history, and the 28mm dome size sits in a sensible sweet spot — large enough for smooth high-frequency dispersion, small enough to push the crossover point usefully high and protect the tweeter from excess excursion. Whether the execution lives up to the specification is something we'll assess properly when review samples arrive, but the foundations look sound.

For a deeper look at what makes a 2.5-way topology different from a conventional two-way design, and how passive radiators compare to ports in real-world listening rooms, I'd encourage readers to revisit our guide on the best standmount speakers for serious listening — the underlying acoustic principles apply directly here.

Connectivity: Cambridge Audio knows its audience

The L/R Series connectivity suite reads like Cambridge Audio surveyed its existing StreamMagic customer base and simply asked: what do you need? The answer is thorough.

• Wi-Fi streaming via StreamMagic: Cambridge Audio's own platform, which has proven itself across the CXN100 streamer and Evo series, supporting high-resolution audio, Roon, Tidal, Qobuz and a broad codec range. Existing StreamMagic users will know the app well.
• HDMI eARC: Critical for television integration. eARC supports lossless audio formats including Dolby TrueHD and DTS-HD Master Audio — a meaningful step up from the optical connections that many competing active speakers rely on. For anyone building a cleaner living room system without a separate AV receiver, this is essential.
• Bluetooth: Presumably aptX or aptX HD, though the specific codec support hasn't been confirmed in the materials available to us — we'll update as details land.
• MM phono input: The inclusion of a moving-magnet phono stage is a statement of intent. Cambridge Audio knows that a significant portion of its customer base owns turntables. The ability to connect a deck like the Rega Planar 3 (check price) directly to the speakers, without an outboard phono stage, removes a friction point that would otherwise force buyers to add another box.
• USB-C: Likely for direct device playback or charging — details pending, but its inclusion acknowledges modern source devices.
• WiSA HT linking: This is the detail that elevates the L/R Series from a stereo-only proposition to something with genuine home cinema ambitions. WiSA (Wireless Speaker and Audio) enables the L/R speakers to be used as front left and right channels in a wider surround system, linking wirelessly with compatible centre channels and surrounds without running speaker cables across the room.

That WiSA inclusion is clever positioning. It acknowledges that buyers at this price point often want a system that can serve both critical music listening and cinematic experiences. For anyone currently thinking through a clean, low-cable home cinema build, our home cinema component guide covers the broader ecosystem decisions in useful depth.

The KEF comparison: how does it actually stack up?

The competitive target is obvious — KEF's wireless active speaker range has owned this category for years, and the LS50 Meta (check price) remains the reference point against which new entrants are inevitably measured. So how does the L/R X compare on paper?

KEF's LS50 Wireless II uses a different topological approach — the Uni-Q coaxial driver places the tweeter at the acoustic centre of the midrange/bass driver, which KEF argues delivers superior point-source imaging. It's a legitimate engineering advantage for soundstage and imaging performance, and KEF's execution of the Uni-Q concept is genuinely world-class. Cambridge Audio's conventional multi-driver layout with the 2.5-way topology and force-cancelling passive radiators takes a different path to low-frequency extension and dynamics.

The L/R X's 800W total power figure is substantially higher than the LS50 Wireless II's amplifier stage, which suggests Cambridge Audio is confident in the dynamic capability of the L/R X, particularly at higher playback levels. Whether raw power translates to audible superiority at realistic listening levels is a question for the listening room, not the spec sheet — but the headroom is there.

Where Cambridge Audio has a genuine structural advantage is ecosystem integration. StreamMagic is a mature, well-regarded platform. Buyers already using a Cambridge Audio CXN100 (check price) or similar in their system will find the L/R Series drops in with minimal friction. KEF's own Control app and streaming implementation have improved over time, but StreamMagic has the longer track record in the Australian enthusiast community.

Aesthetics: six finishes including real walnut

I want to spend a moment on this because it matters, and it's often underweighted in technical coverage. Cambridge Audio has committed to six finishes for the L/R Series, including real walnut veneer. This is a meaningful differentiator. In a category where too many products default to gloss black or matte white, real timber veneer speaks to buyers who care about their listening space as much as their listening experience. The walnut option in particular positions the L/R Series as furniture as well as electronics — a consideration that carries real weight in Australian homes where the speaker is likely to live in a main living area rather than a dedicated listening room.

Active speakers with genuine aesthetic ambition tend to hold their resale value better, too. That's a practical concern for buyers in this price bracket who may want to upgrade in three or four years.

The L/R S and L/R M: democratising the platform

The $549 L/R S is worth acknowledging separately, because it represents an accessible entry point into the StreamMagic active speaker ecosystem. If Cambridge Audio's engineers have made sensible driver and amplification choices at that price point — rather than simply scaling down the L/R X's performance catastrophically — the L/R S could represent one of the more interesting speakers in the sub-$600 active category. That market currently has respectable options from Klipsch, Q Acoustics and KEF's own LSX range, so competition is real. We'll hold final judgement until we can listen.

The L/R M at $1,599 per pair occupies perhaps the most interesting strategic territory — it's priced above casual lifestyle purchases but below the premium active speaker tier, and will likely find its audience among buyers who want genuine streaming performance without the flagship price. For listeners currently considering all-in-one streaming amplifier solutions to partner with passive standmounts, the L/R M is worth adding to the shortlist alongside options in our best streaming amplifiers guide.

What we still need to know

A CES launch provides a framework, not a verdict. There are several things I'll be listening for closely when review samples arrive:

• Low-frequency integration: Force-cancelling passive radiators are a promising approach, but the quality of bass reproduction depends on enclosure tuning, driver matching and DSP implementation. Does the L/R X deliver genuinely extended, controlled bass, or does it trade extension for tightness?
• Treble refinement: The 28mm Torus tweeter has to justify its existence against KEF's Uni-Q and Bowers & Wilkins' aluminium dome competition. Smoothness, air and off-axis behaviour are all under scrutiny.
• StreamMagic implementation: Does the platform's network performance match what we've experienced in the CXN100? Specifically, gapless playback, high-res streaming reliability and app responsiveness.
• Phono stage quality: A built-in MM stage is only valuable if it's genuinely good. A mediocre phono stage can actively degrade the vinyl experience relative to a dedicated outboard unit.
• WiSA integration in practice: Wireless surround systems live or die on latency and reliability. We'll need to test this in a real home cinema context.

Verdict on the launch

Cambridge Audio's L/R Series is the most considered debut in the active wireless speaker category in recent memory from a traditional British hi-fi brand. The engineering decisions — force-cancelling passive radiators, a proper phono stage, HDMI eARC, StreamMagic integration, WiSA support — read like a product developed by people who actually use the things they're designing. The pricing is competitive against the KEF benchmark, the aesthetic range is broader than most competitors, and the three-model spread means there's a genuine entry point at $549 without cheapening the flagship.

Whether the L/R X can genuinely challenge the LS50 Meta's imaging precision and the LS50 Wireless II's streaming maturity remains to be heard. But as opening moves go, this is a strong one. Cambridge Audio has entered the room confidently, and the category is better for it. Review units can't arrive soon enough.
