Cambridge L/R S: Two-minute review

The Cambridge L/R S is the first out of the gate of the British audio brand's new ‘L/R’ wireless range to attack the best stereo speaker systems market. It's also the most affordable: this L/R S sells for Ruark MR1 Mk3-adjacent money, which seems less than accidental.

The money buys a crisply accomplished standard of build and finish, as well as some proper specification highlights — not least of which is that this is an active, rather than a powered, speaker system with a dedicated block of amplification for each of its drivers and an active DSP crossover. A choice of five quite fetching colors doesn’t do any harm, and neither does the option of a real walnut veneer alternative — even if the latter comes at additional cost. Support for aptX HD Bluetooth connectivity, along with line-level analog, USB-C and digital optical inputs, means the L/R S can support a reasonably diverse and expansive set of sources. The provision of a pre-out for a subwoofer is a nice touch, too, although (as we shall directly see) not super-necessary.

No matter the source of the music it’s playing, the L/R S is a big, bold and quite assertive listen; but that’s not the same as saying it’s unsubtle. There’s plenty of detail retrieved to go along with the attack, good insight to complement the dynamism, and a fairly natural and neutral way with frequency response and tonality. Or, at least, there is until you reach the bottom of the frequency range — here the L/R S is rather too confident, and gives a little too much weighting to bass information. This isn’t at the expense of rhythmic expression or forward drive, though.

All of which means the Cambridge L/R S is immediately one of the very best pound-for-pound desktop stereo systems around, and one that demands very careful consideration indeed.

Cambridge L/R S review: Price & release date

• $549 / £399 / AU$949
• Released April 1, 2026 (in US/Europe)
• Originally announced in January 2026

The Cambridge L/R S wireless active stereo speaker system is on sale from April 1, 2026 in Europe and the USA — in APAC (Asia-Pacific) countries it’s already available.

In the United States it will cost $549. Or, at least, it will in any of the five colors in which it will be available — if you fancy the real walnut veneer you're looking at $599. In the United Kingdom it's going to go for £399/£449, while in Australia it is already selling for AU$949/AU$1049.

So the price, as well as the basic configuration, is very close indeed to Ruark’s class-leading MR1 Mk3. Coincidence? Hmm…

Cambridge L/R S review: Features

• 100 watts of Class D amplification
• 21mm tweeter, 76mm mid/bass driver
• Wired and wireless input options

First things first: this is a genuinely active, rather than a powered, stereo speaker system. Any rival product at this sort of money uses one powered speaker to deal with inputs, outputs, amplification, decoding and all the rest of it, and then sends amplified analog information to a passive partner.

With the L/R S, though, Cambridge has gone another, more complex and inevitably more expensive way: although only the primary speaker receives mains power, there are two channels of amplification for each speaker, and a full DSP crossover which serves a PWM (pulse-width modulation) signal to each of the amplifiers. A bespoke four-conductor cable connects the primary speaker to the secondary, along which all power and digital audio signals travel. I don’t think I can be criticized if I use the word ‘over-engineered’ here, so I will – but I am also quite happy to use the word ‘admirable’.

The rear of the secondary speaker features a screw-down socket for connecting that inter-speaker cable, and a bass-reflex slot along the top. The primary speaker has these features too, but it also includes USB-C, line-level stereo RCA and digital optical inputs, plus a pre-out for a subwoofer, and Bluetooth wireless reception (with aptX HD codec compatibility). The optical and USB-C inputs support resolutions of up to 24bit/96kHz PCM – every incoming signal is resampled to 24bit/48kHz in the DSP before its delivery in PWM form to the amplifiers.

Power, incidentally, is of the Class D variety, and there’s 100 watts of it. Each driver gets 25 watts to play with — there’s a 21mm hard-dome tweeter behind a waveguide and phase cap above a 76mm mid/bass driver in each speaker. Cambridge suggests this layout results in a frequency response of 55Hz - 24kHz. The rear of the primary speaker also includes a button that operates as both a power on/off switch and as an input selector. It also features three toggle switches: one to let the speaker know if it’s the left or the right channel, one to tell it if the system is being used on a desktop or not, and one to let it know if it’s in free space or near a wall. And there’s a figure-of-eight socket for mains power, too.

Cambridge L/R S review: Sound quality

• Expansive, detailed and upfront sound
• Direct and positive sonic attitude
• Slightly overplays its low-end hand

Yes, the L/R S is on the larger side for a desktop system but the sound it delivers is appreciably larger than that. Connected via USB-C and with a 24bit/44.1kHz FLAC file of Cate Le Bon’s Are You With Me Now? incoming, the scale and spaciousness of the presentation is initially quite startling.

The overall sense of scale is complemented nicely by the Cambridge’s ability to generate an organized, convincing soundstage and to focus well. There’s a fair amount of separation to the overall presentation, but at the same time a decent sense of singularity that prevents even complex recordings from sounding disjointed or untogether. Add in sufficient dynamic headroom for when the going gets especially loud or intense, and the Cambridge system sounds both bigger and more confident than its physical dimensions might suggest.

The tonal balance is fairly neutral despite a suggestion of heat at the bottom end, and frequency response once you get above the lowest of the low frequencies is smooth and even – the crossover between the two drive units is all-but imperceptible. The top of the frequency range balances attack against substance nicely, while the midrange communicates in a manner easily described as ‘lavish’. The system’s ability to reveal detail of any significance and give it appropriate weighting means voices are delivered with plenty of character and attitude.

There’s a little issue at the bottom of the frequency range. Basically, the Cambridge is slightly too pleased with the amount of low-frequency presence it’s able to liberate from recordings and just fractionally overplays its hand. There’s a little too much emphasis on the bottom end in the context of the overall frequency response available here, a minor bloom at the very bottom of the extension that can make bass sound just a touch too prominent and therefore slightly too remote from everything that’s going on above it.

Despite this, the L/R S controls its low-end activity carefully enough to ensure rhythms are expressed convincingly and momentum levels never dip below where they should be. And besides, I know perfectly well that if it comes to a straight choice, there are plenty of listeners who would choose ‘a little too much bass’ over ‘not quite enough bass’ every time.

All of the above applies if you choose to listen at volume levels somewhere between ‘background’ and ‘really quite loud’. Go beyond that and the L/R S loses a little of its admirable composure and its previously nicely open stage starts to sound a little flat and two-dimensional. It’s hardly a fatal flaw, though, and besides… it’s easily fixed. Just turn it down a touch.

• Sound quality score: 5 / 5

Cambridge L/R S review: Design

• 226 x 134 x 180mm (HxWxD)
• Choice of six finishes, including a (cost-option) real wood veneer
• No grilles supplied

It is, admittedly, a little larger than the Ruark MR1 Mk3 that would appear its primary target, but the Cambridge L/R S is nonetheless compact enough at 226 x 134 x 180mm (HxWxD) to sit happily on even a modestly sized desk (as long as it’s reasonably tidy). At the same time, it’s just about big enough to not look too lost on a pair of regular speaker stands.

No matter where you want to position it, though, there are lightly rubberized little feet integrated into the bottom of the recessed plinth on which the main body of the speaker sits (which is why, from some angles, it seems to float), and there will be the option of a pair of angled ‘tilt’ stands to help aim the tweeters more overtly at your ears if the system is on your desk. These stands, of course, are a cost option.

There’s not even the option of any grilles, though. Having said that, there’s a hint of visual interest thanks to the identically sized black circles on the front baffle inside which the drivers are positioned which wouldn’t be available if grilles were fitted. Nor is there much to be gained in aesthetic terms by hiding away the orange tweeter or its waveguide, either.

The standard of construction is beyond reproach. The cabinet edges and corners are crisp rather than pointy, the recently updated brand logo at the rear of the top surface looks confident, and the sort-of kind-of matte finish feels as good as it looks in any of the five colors that are available. Take your pick from the white of my review sample, black, a bright orange, a fairly dark green or an unarguably dark blue — or if you don’t object to some extra expenditure, you can choose a real walnut veneer that tackles the L/R S even further into Ruark MR1 Mk3 territory.

• Design score: 4.5 / 5

Cambridge L/R S review: Usability & setup

• Bluetooth LE remote control
• Selection of EQ presets
• ‘DynamEQ’ technology included

First of all, of course, the primary speaker must be plugged into the mains. Then use the supplied 2m length of cable to join the two speakers together (Cambridge is readying a 5m alternative, for which it will naturally want some more money). After that, it’s just a question of establishing the physical or wireless connections you need to make.

There is no control app here, of course — this is not a networked system, after all. Nor are there any physical controls on either of the speakers (except that trio of toggle switches that help orientate the system before it’s running, the on/off power button or to cycle through the inputs), which could be considered an oversight. The only way to control the L/R S is by using the remote control handset that’s supplied in the packaging.

The handset itself is small, made of quite hard plastic and is not backlit but it covers off every function, and because it’s a Bluetooth rather than an RF device it’s far less reliant on having line of sight to the ‘primary’ speaker. It also gives access to a trio of EQ presets: they’re designated ‘normal’, ‘movie’ and ‘voice’.

Cambridge has included its ‘DynamEQ’ technology here, which is a gesture towards automated usability. It’s described as ‘intelligent optimization’, and makes bass and treble adjustments in response to any changes in volume you might indulge in.

• Usability & setup score: 4.5 / 5

Cambridge L/R S review: Value

• Excellent sound for the price
• Lots of colorways, even if you have to pay extra for the walnut finish
• Expansive specification

Judge it in terms of engineering excellence, obvious competence where construction and finish are concerned, and the useful and reasonably expansive nature of its specification, and it’s hard to suggest the Cambridge L/R S doesn’t represent decent value for money.

And when you factor in the sound it’s capable of producing, well, it then starts to put it squarely in the 'market leaders' bracket for active speaker systems.

• Value score: 5 / 5

Should I buy Cambridge L/R S?

Cambridge Audio L/R S review: Also consider

How I tested the Cambridge L/R S

I tested the L/R S on a desktop, where it was wired via USB-C to an Apple MacBook Pro running Colibri software.

It was also connected wirelessly to an Apple iPhone 14 Pro (via the AAC codec) and a FiiO M15S (using aptX). It was also tested when positioned on a pair of Custom Design speaker stands and with a (pre-amplified) Technics SL-1300G turntable and Rega Apollo CD player connected to the analog RCAs and the digital optical socket respectively.
