Q Acoustics M20 HD

Most reviewers hear a balanced, slightly warm presentation — AVForums' notes say 'balance', HIFI.DE 'harmonious and relaxed', Pocket-lint a 'nice level of warmth'. A minority hear a shape rather than a balance: SECRETS calls it U-shaped with slightly recessed mids, ON-mag hears bass pushed forward with the ports open, and one returning owner found the mids and bass weak.

“The word littered across my listening notes is ‘balance.’”

AVForums (Ed Selley)

“The sound is detailed and spacious with a nice level of warmth that makes the music feel rich and inviting.”

Pocket-lint

“the M20 HD sounds U-shaped in frequency response, with a bump in the bass and highs”

SECRETS (Taps Das; 7–8 in from the wall)

Solid, punchy and fuller than a 5-inch driver suggests in most reports, with STEREO calling it 'very profound' for the size and AVForums finding the 55 Hz rating bettered in its room. It doesn't go truly deep — SECRETS says a sub is needed for the lowest octave and one owner returned it for lacking bass — while ON-mag heard the opposite problem with the ports open and fitted the supplied foam bungs.

“Klanglich klingt er für die Größe und den Preis sehr profund.”

STEREO 12/2021 — “for its size and price it sounds very profound”

“that 55Hz figure at +/- 6dB is effortlessly bettered in this room”

AVForums (on Soundstyle stands)

“A sub is truly required for the lower depths.”

SECRETS

“En revanche, les basses ne sont pas aussi raffinées, car sensiblement mises en avant.”

ON-mag — “the bass, by contrast, is less refined, being noticeably pushed forward” (ports open)

Voices are a highlight for most — clear, present and natural, the 'best' part of the speaker to L&B. SECRETS hears the midrange slightly recessed, Hi-Fi World measures a small dip at the crossover, and one returning owner called the mids 'pretty bad' over Bluetooth.

“The best, however, is the midrange, which is more free and undistorted than we are used to at the cheapest end.”

L&B Tech Reviews

“Stimmen bleiben mittig und glasklar, selbst wenn der Bass noch so starke Impulse in deine Richtung schickt.”

HIFI.DE — “voices stay centred and crystal clear, however hard the bass pushes”

“The mid-range sounds slightly recessed.”

SECRETS

Sources split. Most reviewers hear a refined, smooth top end that never turns harsh, and one long-term owner even finds it a little rolled off. Hi-Fi World heard a sharp edge and measured a treble rise it traced to the amplifier, not the tweeter, and several owners report harshness, sibilance or ear fatigue — in some cases easing in a bigger room, over RCA rather than optical, or with treble turned down.

One of the clearest agreements: a wide, spacious stage for the size, from What Hi-Fi?'s 'expansive' to LowBeats' broadly fanned stage. SECRETS calls it good but 'not too expansive'.

“Insightful and spacious presentation”

What Hi-Fi? (verdict)

“Die Bühne zwischen den Boxen ist breit gefächert, wobei einzelne Klangereignisse erstaunlich plastisch zwischen den Boxen erscheinen und bei Bewegung zentimetergenau zu verfolgen sind.”

LowBeats — “the stage is broad, with individual sounds standing out vividly and traceable to the centimetre”

“The soundstage is good, not too expansive”

SECRETS

Focused, stable imaging — Stuff and LowBeats credit the braced cabinets, AREA DVD calls the stereo effect excellent, and an Amazon owner picked it over Klipsch's The Fives partly for the clarity of its stage.

“The presentation is full-scale, focused and completely convincing.”

Stuff (Simon Lucas)

“I was amazed by the wide soundstage and the clarity that the M20 provide.”

Amazon UK owner (verified, vs Klipsch The Fives)

Detailed and insightful for the money to most reviewers, with LowBeats praising the treble resolution for the class. L&B and AREA DVD note the limits — it could be more resolved and freer, and Q Acoustics' own pricier Active 200 is in another league — and Hi-Fi World calls the sound good rather than startling.

“The sound could easily be more well-resolved and free, but this is probably due to limitations in the built-in amplifier and DAC, rather than the speakers themselves.”

L&B Tech Reviews

“Der Hochton überzeugt mit einer für diese Klasse sehr guten Auflösung und ist dabei niemals lästig oder spitz.”

LowBeats — “the treble convinces with very good resolution for its class and is never annoying or sharp”

Sources split on how loud it goes. What Hi-Fi?, AVForums, AREA DVD and STEREO found it punchy and loud enough for a large room; Hi-Fi World ran into a limiter that stops it going louder, L&B found dynamics 'not their best card', and LowBeats heard limited headroom and port noise on bass-heavy tracks at higher levels.

Placement guidance rather than a split. It's forgiving — What Hi-Fi? and ecoustics got good results 20 cm from the wall or on a credenza — but the rear port wants room to breathe, the cabinets are nearly 30 cm deep, and stands help. Close to a wall, use the wall/corner switch or the foam bungs (ON-mag preferred it bunged); one owner instead moved them nearer the walls for more bass. For a small desk, one buyer found them too big and preferred smaller speakers.

“Unfussy placement-wise”

What Hi-Fi? (verdict)

“But do not squeeze them into a bookshelf, as the bass ports on the back needs room to “breathe”.”

L&B Tech Reviews

“They’re nearly 30cm deep which rules out many options, though not those Ikea units that everyone seems to love.”

Stuff

“Nous avons donc opté pour l'utilisation des mousses/filtres (fournis) afin d'obstruer les évents bass-reflex à l’arrière.”

ON-mag — “so we chose to use the supplied foam plugs to block the rear bass-reflex ports”

Few reviewers mention self-noise at all. One owner comparing it with Kanto's YU2 at a desk heard more background whine and an odd pressure sensation; Hi-Fi World measured Class D noise rising above 10 kHz. Q Acoustics' support pages also cover a pop when playback starts over USB on Windows.

“I found that the M20's when playing audio had more background whine, and gave a weird pressure feeling in the ears”

aljowen (YouTube, owner; near-field desk vs Kanto YU2)

Generous wired connections for the price — USB from a computer, optical for a TV, RCA and 3.5 mm line inputs, aptX HD Bluetooth and a subwoofer output. What's missing comes up repeatedly: no Wi-Fi, AirPlay or Spotify Connect, no HDMI ARC for TV volume control, and no phono stage.

“Great connectivity options”

What Hi-Fi? (verdict)

“But for an all-in-one system, no Apple AirPlay or Spotify Connect feels like more of a miss than it perhaps should”

Stuff

“An ARC HDMI input would have been better, though, as the volume could then be controlled on the TV’s remote control.”

L&B Tech Reviews

Easy to set up, with a neat remote, but daily use has rough edges. It drops to standby after 20 minutes without signal (the most common owner complaint) and doesn't remember the last input; the USB input was erratic for several reviewers and owners; and there's no on-front indicator, volume steps can feel uneven, and the bass switch is fiddly.

“It was a very easy system to set up and use I found.”

Hi-Fi World, via 7Review

“My only real gripe is that the functionality around the USB input seems a little inconsistent.”

AVForums

“The speaker doesn’t remember the last used input when you fire it up but defaults to the digital connection, kind of a pain, but not a deal-breaker.”

SECRETS

“They turn off too soon if no audio”

Amazon UK owner (4★, verified)

Solidly made and well finished for the price — STEREO rates it well above the class average, and AVForums finds the cabinets inert. ON-mag calls the assembly flawless but nothing premium, with a vinyl wrap. The grilles are fixed, which several reviewers dislike; Q Acoustics says that matches its Media range. One owner's USB port failed after three to five years.

“Die Verarbeitung liegt deutlich über dem Klassendurchschnitt.”

STEREO — “the build is well above the class average”

“L'assemblage ne souffre d'aucun défaut, mais n'a rien de premium non plus.”

ON-mag — “the assembly has no flaws, but nothing premium either”

“the grilles aren't removable for some reason, which we thought was a shame”

Pocket-lint

Strong value to almost every reviewer — AVForums' best in class, Stuff's 'cannot spend it any more wisely', and value is Amazon UK owners' second most-praised topic. The dissenters point to alternatives: a returning owner found Kali's LP-6 monitors a different league for a little more, a desk user preferred much cheaper Kanto YU2s up close, and L&B heard better resolution from Argon's Forte A4.

“If this is the sort of budget you have with which to build the bulk of a hi-fi system, you absolutely positively cannot spend it any more wisely.”

Stuff

“The Q Acoustics M20 is one of the best of its kind right now and is worth every penny of its $599 asking price.”

ecoustics (Ian White)

“For more or less the same money i bought a pair of Kali Lp6 wave 2 monitors that are in completely different league.”
