Compare Edifier M90 vs Cambridge L/R S

Most listeners found the sound clean and controlled even when pushed hard, with little hiss or obvious distortion. At extreme levels, bass can become boomier and a few tracks lose some composure.

Very high volume is the clearest sonic limit: the stage can flatten, become shouty or compressed, and demanding bass can introduce audible strain. One first-listen report found the broader L/R range clean at high levels, but the S-specific tests are more cautious.

Hi-res wired processing and LDAC playback preserve more detail than basic Bluetooth, with a clearly audible benefit on compatible high-resolution material.

The digital inputs top out at 24-bit/96kHz, and one test found a higher-resolution SACD rip would not play. That is adequate for common desktop use but restrictive for listeners with higher-resolution source libraries.

The remote buttons respond quickly, have practical sizing, and remain easy to use in a dark room.

Remote button response can occasionally lag enough to require another press. It is not constant, but it happens often enough to make control feel less immediate than it should.

Detail and clarity remain intact at apartment-friendly listening levels, making the M90 especially effective for quiet desktop use.

DynamEQ helps quiet listening retain punch and tonal body, so background-level playback stays natural and engaging. The speakers still reveal more of their ability once the volume rises beyond very low levels.

The generously long speaker-to-speaker cable allows proper stereo spacing across desks, shelves, and TV stands.

The speaker-to-speaker link feels unusually well engineered, with a secure locking connection and a sophisticated active architecture. The tradeoff is that the pair must be physically linked, with no wireless inter-speaker option.

The compact radio remote is highly useful for volume, inputs, playback, and EQ presets, and it works without line of sight. Because the physical controls are on the rear, the remote becomes nearly essential.

The Bluetooth remote is functionally comprehensive and does not need line of sight, but its execution is mixed. Hard plastic, no backlight, occasional lag or sync issues, and heavy dependence on the handset all reduce convenience.

The regular price is a noticeable jump from the M60 and can feel high for a single-purpose desktop setup. Discounts make the proposition much easier to justify.

The asking price lands differently depending on expectations: one source calls it remarkably affordable, while another sees it as premium for desktop speakers. The performance and finish make the extra spend feel worthwhile for serious listeners.

The bi-amplified design gives the compact speakers strong punch and reserve, keeping music and movie effects lively as volume rises.

There is ample dynamic headroom through normal and fairly loud listening, and energetic passages can sound confident and lively. Some material still feels a touch reserved, and the advantage fades as the system approaches its volume ceiling.

TV and movie dialogue comes through crystal clear, nuanced, and naturally centered, even during busy scenes.

The Voice and Movie modes make speech more prominent by lifting the mids without becoming excessively aggressive. That makes podcasts, dialogue-heavy TV and movie use easier to follow.

The exposed drivers have no grilles, leaving the soft tweeters vulnerable to curious fingers or accidental contact.

Driver protection is mixed because the speakers have no grille option, leaving the woofer exposed to fingers. The tweeter's phase cap does provide some useful physical protection.

The M90 gets far louder than most desktop setups require and comfortably fills small to medium rooms. Output remains impressive in larger spaces, though the compact drivers cannot match full-size speakers.

It plays surprisingly loud for a compact desktop pair and can fill offices and small rooms with ease. The strongest results come below all-out volume, where composure is better preserved.

LDAC provides unusually strong wireless quality for this class, while AAC keeps iPhone playback respectable. LDAC is unavailable on Apple devices and cannot be used simultaneously with multipoint.

aptX HD is viewed as a solid choice for higher-quality Bluetooth listening. It gives the wireless side of the system more credibility than basic Bluetooth alone.

HDMI eARC, optical, USB-C, AUX, and sub-out cover nearly every desktop, TV, and legacy source. Multiple devices can remain connected and be switched without moving cables.

USB-C, optical and RCA give the system useful wired flexibility, with USB-C setup described as immediate and sound quality remaining consistent across digital inputs. The wired options are a strong part of the desktop-friendly design.

The nine-band EQ and saveable presets make meaningful tonal and room corrections easy, with presets accessible from the remote. Power users may miss full parametric EQ, and some changes require a Bluetooth app connection.

The EQ options are subtle rather than dramatic, with Normal usually preferred for balanced listening and Voice or Movie useful for specific content. Placement EQ can make a noticeable improvement when the desk or wall setting matches the room.

The only physical knob and power control sit on the rear of the active speaker, making direct adjustments awkward. Most users will rely on the remote, app, or TV remote instead.

On-device control is one of the clearest weaknesses. Beyond rear-mounted power/source and setup switches, there is no convenient speaker-mounted volume or mute control, leaving everyday operation heavily dependent on the remote.

The optical input is handy for televisions, media players, and older digital sources. It sounds good, though it does not support the same automatic wake behavior as HDMI.

Optical is a practical TV connection and was singled out as the preferred route when HDMI is unavailable. It works well, but it does not offer the same convenience as HDMI ARC.

Bass is punchy, fast, and unusually authoritative for four-inch drivers, with little muddiness or bloat. Deep sub-bass and large-room impact remain limited, so bass-heavy listeners may want a subwoofer.

Bass is strong for the cabinet size, often described as tight, punchy and surprisingly full. Opinions split on tuning: some hear a little too much warmth or bloom, while deeper sub-bass and extreme-volume impact remain physically limited.

The combination of sound quality, HDMI eARC, broad inputs, app EQ, and compact size makes the M90 strong value as an all-in-one system. One customer preferred a much cheaper alternative, but the wider consensus is highly favorable.

Value is generally strong once sound, build and engineering are considered together. It costs more than some desktop alternatives, but the combination of scale, imaging, finish and simplicity repeatedly makes the premium feel defensible.

The overall tuning is warm-neutral or broadly balanced, with strong bass and clear vocals. Depending on preset and placement, the mid-high range can sound cool, dry, recessed, or slightly rough, making the nine-band EQ especially useful.

The overall balance is generally smooth, even and close to neutral, making long sessions easy to tolerate. It is not strictly reference-flat, though, with some bass warmth and a touch of enjoyable sonic coloring.

Bluetooth and HDMI wake quickly, but USB-C, optical, and AUX may require the remote or app. The aggressive default sleep behavior can interrupt quiet content, though firmware and app settings can largely fix it.

Automatic standby works, but waking from an idle state can take roughly seven to eight seconds. That delay is long enough to miss the opening seconds of content unless playback is restarted.

HDMI eARC, CEC, clear dialogue, and wide stereo imaging make the M90 an excellent bedroom or office TV upgrade. Larger rooms and effects-heavy movies may still need a subwoofer or bigger speakers.

In bedrooms, offices and other small rooms, the pair can serve as a convincing TV or soundbar alternative with wide, theater-like presentation. Optical connection works well for that role, though HDMI ARC is not available.

The box includes a generous cable selection, but a few customers received defective USB-C or power cables that required replacement.

The basic package covers power, the inter-speaker link and remote control, but source cables are sparse. USB-C, RCA and optical cables may need to be supplied separately.

The compact footprint and substantial output are an excellent match for desks, bedrooms, offices, apartments, and small to medium living rooms.

The L/R S is especially well suited to desks, offices, bedrooms and other smaller spaces, where its compact footprint can still produce room-filling scale. It is larger than some desktop rivals, so very narrow desks need more care.

Directional effects are easy to track, with strong impact and spacious rendering for desktop or couch gaming. HDMI eARC also keeps TV gaming responsive.

Gaming benefits from the strong low end and precise directional imaging, giving explosions more impact and positional cues more clarity. The same spacious presentation that works for music translates well to games.

Bluetooth pairing is quick and straightforward, making casual phone and tablet playback easy.

Bluetooth connectivity is straightforward, with pairing described as immediate, easy or a breeze across phones used in testing. It fits the system's simple, no-network approach well.

The speakers create a wide, stable stereo image with convincing center vocals and precise placement. A few demanding recordings reveal less pinpoint separation than dedicated hi-fi monitors.

Stereo imaging is a standout strength, with wide, precise placement, a solid center image and an unusually spacious feel for the cabinet size. Careful toe-in or tilt helps preserve that focus, especially off-axis.

Voices sound clear, forward, and full-bodied across music, podcasts, and TV. They remain intelligible without becoming shouty or thin.

Voices come through with strong character, clarity and stable placement, from spoken content to sung vocals. Even more critical takes still describe the vocal presentation as natural and easy to follow.

Highs are generally smooth, detailed, and comfortable for long sessions. Some listeners heard recessed, cool, or slightly rough upper frequencies, which the EQ can usually tame.

Treble is usually smooth, clear and substantial without turning sharp or sibilant, which helps long listening sessions stay comfortable. A more critical take hears a slight upper-frequency rolloff that trades accuracy for forgiveness.

The dense MDF-style cabinets feel solid, rigid, and more premium than typical computer speakers. One unit showed average panel fit, but most found the enclosure impressively substantial.

Cabinet construction feels unusually solid and premium for the size, with crisp edges, dense enclosures and finishes that hold up in more upscale rooms. Build quality is one of the safest reasons to justify the price.

The dedicated sub output makes it easy to add deeper extension. Many desktop listeners will be satisfied without one, while action movies and bass-heavy music benefit clearly from a subwoofer.

The subwoofer output is a welcome expansion path, though the built-in bass is strong enough that some listeners may not feel an immediate need for one. A sub becomes more worthwhile if deep low-end extension is a priority.

Drivers blend smoothly into a unified, clean presentation, with vocals and instruments remaining organized across music, games, and video.

The presentation stays cohesive even while creating plenty of space between instruments. Complex material tends to feel layered and unified rather than fragmented or disconnected.

Most setups are plug-and-play, with USB-C and HDMI working in minutes. Docking-station arrangements and the app's Bluetooth connection can require extra troubleshooting or clearer instructions.

Setup is one of the easiest parts of ownership: Bluetooth pairing can take seconds, USB-C is recognized quickly, and the placement switches are simple to understand. The self-contained active design also avoids amplifier setup.

Vocals, instruments, and small textures are generally clear and well separated. The smooth upper treble can occasionally blend fine details on dense recordings.

Detail retrieval is consistently strong, revealing fine textures, small harmonic changes and background elements without making the presentation clinical. Resolution remains convincing across Bluetooth, USB and other sources.

Music sounds lively, clean, and enjoyable across genres, with rich vocals, punchy bass, and useful detail. The tuning favors accessible long-session listening over strict studio-monitor neutrality.

Music is the core strength: the speakers sound lively, spacious, detailed and engaging across rock, electronic, jazz, classical and other material. The voicing favors enjoyable, fatigue-free listening over strict studio-monitor neutrality.

The black and white matte finishes look clean, modern, and easy to match with a desk or TV stand. The surfaces resist fingerprints and everyday marks well.

The finish selection is unusually broad and attractive, ranging from restrained black and white to orange, green, blue and real walnut. Walnut costs extra, and the black finish can show fingerprints, but the visual choice is a clear strength.

The restrained, boxy design looks modern and purposeful without flashy styling. It blends easily into desks and living rooms, although the busy rear panel is less elegant.

The clean, minimal cabinet design is one of the most consistently praised aspects of the product. Crisp lines, the exposed copper/orange tweeter and premium-feeling finishes give it a modern look that works on desks or in living spaces.

The active, bi-amplified design needs no separate receiver, DAC, or power amplifier, simplifying both desktop and TV systems.

Because amplification is built in, no separate amplifier is required. That self-contained approach is a major part of the product's simplicity and desktop appeal.

The crowded rear panel can turn into a visible tangle when several sources are connected at once.

The included inter-speaker cable is short for lowboard, shelf or wider stereo placement. A longer cable is available, but broader layouts may require that extra purchase.

AirPlay 2 is absent, so the M90 cannot join an Apple multi-room setup and must rely on Bluetooth or wired connections.

ConneX is usually fast, clear, and stable, with useful input, firmware, and EQ controls. It can feel basic, sometimes requires Bluetooth for changes, and a few users found reconnection or setup unnecessarily fiddly.

A clean, quiet background helps small details emerge without obvious hiss or grit. Low noise and low distortion at normal listening levels contribute to the polished presentation.

AUX and optical inputs make it easy to use turntables with preamps, older media players, and legacy televisions.

Pairing is usually fast and stable at normal room distances. An isolated customer report found repeated disconnections when using Bluetooth with a TV.

HDMI eARC is a standout strength, delivering simple TV setup, reliable CEC volume control, and strong audio quality. It makes the M90 a convincing alternative to a compact soundbar.

HDMI eARC provides responsive, well-synced TV and gaming audio. One customer encountered noticeable Bluetooth video delay, so wired TV use is the safer choice.

Midrange performance is the most divided part of the tonal picture. Some listening finds it crisp, clear and beautifully expressive, while other tests hear a slight veil, less energy and reduced nuance compared with stronger rivals.

Multipoint makes switching between two devices convenient and generally seamless. Enabling it disables LDAC, so shoppers must choose convenience or the highest Bluetooth quality.

As a complete product, the L/R S combines premium build, attractive design, easy setup and broad small-room versatility unusually well. It is better framed as a polished lifestyle hi-fi system than a purist studio tool.

Overall sound quality is the product's strongest consensus point: spacious, refined, detailed and much larger-sounding than the cabinets suggest. The main caveats are bass tuning, slightly restrained mids in some tests and reduced composure at the very top of the volume range.

The M90 produces unusually wide, deep, and tall staging for its size, especially over HDMI or optical and with careful placement.

The color-coded LED makes input identification straightforward, but feedback is otherwise sparse. Precise volume status is difficult to judge, and the lack of a volume indicator is a recurring usability limitation.

The wide front stage gives flyovers and directional effects convincing space, but it remains a stereo system rather than true surround sound.

Recycled cardboard-style protective forms reduce packaging waste while still keeping the speakers well protected.

HDMI eARC and CEC connect reliably, wake quickly, and let the TV remote control volume and power without fuss.

The speakers have reassuring heft but retain a compact, desk-friendly footprint. They are easy to position on shelves or media consoles without feeling flimsy.

There is no Wi-Fi streaming, direct music-service support, or multi-room playback, which is a notable limitation for shoppers wanting a networked speaker.
