S3 Mk3

The hobby of audio sometimes embodies contradiction. We yearn to be moved by music, yet in reality, we’re captivated by minute differences in equipment. We seek emotional torrents while immersing ourselves in cold analysis. A speaker that strikes right at the center of this contradiction has emerged: the MAGICO S3 Mk3 (2023 model). This is not merely a model change. It’s an extremely strategic product where founder Alon Wolf’s obsessive design philosophy fuses with technical essence that trickled down from flagship M9, set to destroy the “common sense” of this price range.

In this article, we dissect without bias, on both subjective and objective wheels, what the sound produced by MAGICO S3 Mk3 brings to our ears and hearts. This is not a catalog of product praise. It’s an attempt to present one coordinate axis for measuring the current position of high-end audio.

1. Global Reception

Since its debut, the S3 Mk3 has attracted attention from media and users worldwide. However, its reception is not uniform. Here, we overview representative reviews and decode the biases behind them to reveal a more essential picture.

MediaQuote Excerpt (Original)Rating
The Absolute Sound”Here is a truly great dynamic loudspeaker that competes with (and in some ways exceeds) the twice-as-expensive competition.”★★★★★
Hi-Fi+“The S3 images like a point source but has a three-way midrange clarity and a gut-puncher bass… you are listening ever deeper into the music…”★★★★★
Soundnews(With Accuphase combination) “…a highly engaging, holographic presentation that allowed the S3 Mk III to truly shine.”★★★★☆
AudioShark Forum”It quickly became obvious that it is not just an improved iteration of the previous S3 MkII… It is just that good.”★★★★★
ASR Forum (Show Report)“Just had a listen to the S3 at a show… Got to say it did not sound good to me… strident and hard.”★★☆☆☆

Summary and Bias Analysis: The majority of major sources surveyed give extremely positive evaluations. Specialized publications like The Absolute Sound and Hi-Fi+ in particular lavish praise based on long-term listening and detailed analysis 7. User forums also feature enthusiastic reports from users who auditioned in ideal environments at the manufacturer’s headquarters or dealers 10. On the other hand, the few negative opinions deserve careful attention—most are based on auditions in the special environment of audio shows 11. This is not mere coincidence. Rather, it paradoxically proves the essence of S3 Mk3.

As pointed out in many reviews, S3 Mk3 is an extremely transparent speaker faithful to source 8. Such speakers ruthlessly expose acoustic defects in upstream components and rooms. When played in acoustically inferior hotel rooms with hastily assembled systems, sounding “strident and hard” is almost inevitable. More “forgiving” speakers, or those with their own character, might sound acceptable even in poor conditions. The fact that S3 Mk3 cannot gloss over inferior environments is, conversely, evidence of its uncolored, high-fidelity reproduction capability.

2. Fetishization of Design Philosophy: Technical Dissection of S3 Mk3

Understanding Magico speakers equals understanding founder Alon Wolf’s philosophy. His ideology condenses to one point: “speakers should disappear” 9. Add nothing to the music signal, subtract nothing. To realize this ideal, he turns his back on industry conventions, investing cost-no-object resources and cutting-edge science. S3 Mk3 is the latest crystallization of that philosophy.

Enclosure: Gospel of Inertia

For Wolf, the greatest source of distortion in speakers is the enclosure. He dismisses MDF—inexpensive and easy to process but low in rigidity and prone to energy storage—as “the worst material among usable ones” 14. His answer is an aluminum cabinet pursuing absolute mechanical inertia.

The S3 Mk3 enclosure evolved from the traditional single-extrusion (monocoque) structure, now composed of four independent extruded aluminum panels ranging from 1/2 inch to 2 inches thick 5. The curved top panel minimizes diffraction, and the newly designed three-point outrigger system lowers center of gravity and enhances stability 16—every shape has acoustic meaning.

Particularly noteworthy is the introduction of their proprietary 3D laser interferometry system. This enables precise measurement of cabinet resonance at over 1,000 points, allowing strategic placement of internal bracing and damping materials 5. As a result, enclosure quietness improved by 30% compared to the previous model 8. This is no longer furniture—it’s the realm of precision instruments.

Drivers: Descendants of M9

The greatest factor catapulting S3 Mk3’s performance is the injection of technology cultivated in developing the $750,000 flagship model, M9 7.

  • Tweeter: Adopts a 28 mm diamond-coated beryllium dome inheriting M9’s platform 15. Utilizing finite element analysis (FEA), diameter increased from 26 mm to 28 mm. This achieved higher power handling and lower distortion without increasing mass 15. This isn’t improvement of off-the-shelf products—it’s a demonstration of Magico’s technical prowess.
  • Midrange & Bass: The 5-inch midrange and two 9-inch woofers employ the latest Generation 8 “Nanotech Cone.” This is a composite material with aluminum honeycomb core sandwiched between carbon fiber and graphene on both sides 5. The goal is singular: maximizing stiffness-to-weight ratio. This achieves extremely fast transient response and low distortion. Adopting newly developed foam edges in place of traditional rubber also contributes to improved responsiveness 10.

Crossover: The Invisible Conductor

Less discussed but crucial to Magico sound is the proprietary “Elliptical Symmetry Crossover (ESXO)” network. Designed to achieve steep 24 dB/oct slopes with fewer components than conventional circuits, it minimizes phase characteristic disturbances and signal degradation 20. Like an excellent screenwriter maximizing the performance of driver unit actors.

$50k Battlefield: Specification Comparison

To understand S3 Mk3’s technical choices, comparison with rivals in the same price range is essential. The following table highlights differences in each manufacturer’s design philosophy.

From this table, fundamental design philosophy differences emerge: sealed vs. bass reflex, metal cabinet vs. composite materials. These are the wellsprings determining each model’s sound character.

3. Can Measurements Tell Music?: Considerations from Objective Data

Subjective impressions are attractive, but audio criticism should also be science. Fortunately, detailed measurement data published by Hi-Fi News magazine allows objective analysis of S3 Mk3’s physical behavior.

  • Frequency Response: The measured frequency response is remarkably flat, with left-right pair matching error of only 0.6 dB and response deviation within approximately ±1.7 dB 21. This is objective evidence supporting the “neutral” and “uncolored” descriptions in subjective reviews.
  • Impedance: The nominal 4 Ω specification is this speaker’s most dangerous trap. Actual impedance curve drops to 2.7 Ω around 95 Hz, with large phase angles in other bands 21. This is an extremely demanding load for amplifiers, suggesting ordinary drive capability cannot fully control the speaker.
  • Distortion (THD): Even at loud 90 dB SPL, distortion records astonishingly low figures: 0.55% at 100 Hz, merely 0.2% at 1 kHz 21. This is direct result of high-rigidity drivers and resonance-free enclosure, providing technical basis for auditory impressions of “no breakdown even at high volume” and “sound rising from silence” 8.

The conclusion from this data is singular: For S3 Mk3, amplifiers are not mere accessories but essential components for performance.

This fact is vividly demonstrated in Soundnews magazine’s review 9. The review reports that combinations with Accuphase or Pass Labs amplifiers—with strong current supply capability—produced “holographic and engaging” sound, whereas McIntosh monoblock amplifiers, despite being high-power, resulted in “flat and congested” sound.

This isn’t about amplifier superiority but compatibility. S3 Mk3 demands amplifiers with “strong foundation” capable of stably supplying large current to low-impedance loads. Before choosing amplifiers by tonal preference, the technical prerequisite of whether they can drive the speaker must be cleared. This is precisely why Magico frequently demos with brands like Soulution and Constellation 11.

What the 36kHz Peak Means: A Defect or Evidence of Design?

When you examine the frequency response graph in Hi-Fi News magazine closely, you can identify a sharp peak near 36kHz. While this may initially appear to be a defect, it is in fact a crucial indicator proving the validity of Magico’s design philosophy.

The true nature of this peak is the “primary resonance (breakup mode)” inherent to the diamond-coated beryllium tweeter diaphragm itself. An extremely hard and lightweight material like beryllium can maintain ideal piston motion within the audible range (~20kHz), but every physical object has its own resonant frequency. Magico’s design objective is to push this resonance point as far away from the human audible range as possible—into the far reaches of the high-frequency domain.

The fact that this peak exists in the ultrasonic region at 36kHz is proof that this design has succeeded. In other words, it means that across all frequencies up to 20kHz contained in music signals, the tweeter operates with extreme precision, unaffected by resonance.

This peak itself cannot be “heard.” However, its indirect benefits are immeasurable. The fact that the resonance point lies in the far high frequencies means that distortion and coloration caused by resonance are virtually absent within the audible band. This is the technical foundation for why many reviewers describe the high frequencies of the S3 Mk3 as “extremely refined,” “airy and delicate,” and “clean and pure.” This peak is not a defect, but rather a beautiful result of intentional engineering designed to achieve overwhelming transparency in the audible range.再試行

4. Resolution of Sound, Resolution of Heart: Listening Impressions

Technology and data show speaker “capability,” but how it resonates as “music” requires actual listening. Here, let’s journey through the sonic world S3 Mk3 creates, borrowing words from trusted reviewers.

Reviewer / MediaQuote Excerpt (Original)
Jonathan Valin / TAS”…in-room measurement, was going down to an astonishing 20Hz… I have never heard a small floorstanding cone loudspeaker that does as much as this one does for the money…”
NekoAudio / AudioShark”The midrange and bass is clearly more detailed and faster… I wasn’t sure if I was hearing the musician breathing or if it was my own…”
Steve May / The Luxe Review”Transients are effortlessly fast, and bass notes solid and deep without unnecessary excess… I constantly hankered for more volume – what I didn’t realise… was just how loud they were already playing.”
cpunter / AudioShark”The treble is ultra-refined, airy, and delicate yet not soft. The midrange is pure, clean, and detailed, yet majestic and smooth…”

Genre-Specific Performance

  • Classical (Orchestral): This is likely where S3 Mk3’s true value shines most. Low distortion, vast dynamic range, and pinpoint imaging capability combine to prevent saturation even with large orchestras, clearly separating each instrument’s part 10. As Jonathan Valin reported, the soundstage spreads wall-to-wall 7, and the deep yet non-bloated sealed-type bass provides unwavering foundation to grand-scale music 19. Reproducing minute textures like timpani skin tension and contrabass body resonance is stunning.
  • Jazz & Vocal: The midrange “purity” and “transparency” reviewers unanimously praise shines with small jazz ensembles and vocals 8. Resolution so realistic you can sense performers’ breathing, as NekoAudio experienced, drags listeners to the recording venue 10. Importantly, S3 Mk3 isn’t a “beautiful sound” speaker. Rather than adding warmth or luster makeup, it presents information in recordings as-is. It possesses monitor-like character, portraying even microphone characteristics and studio reverberation.
  • Rock & Electronic: The sealed enclosure’s benefit appears prominently in rhythm-focused music. Rather than overwhelming with bass “quantity,” it captivates with “quality.” Bass described as “fast,” “controlled,” and “clear” 10 easily unravels complex basslines in electronic music. Even with intense rock drum solos, each note’s attack and decay doesn’t muddle. And as Steve May points out, extremely low distortion means volume unknowingly increases 27. This is evidence of speakers effortlessly releasing music’s energy into space without stress.

5. Between Value and Price: Overall Evaluation

In absolute price terms, S3 Mk3 is a product only a select few enthusiasts can own. However, to properly evaluate its value requires the special yardstick of the high-end market.

Evaluation AxisScore (out of 5)Commentary
Technical Performance★★★★★Concentration of state-of-the-art technology in current passive speakers. Enclosure, drivers, measurement-driven design philosophy represent the pinnacle of technology. Objective measurement data proves its low distortion and excellent frequency characteristics 8.
Musical Appeal★★★★☆Overwhelming information quantity and dynamism are unparalleled. However, its extreme honesty may feel “cold” or “analytical” with poorly recorded sources or incompatible equipment. A tool for purists that faithfully reproduces recorded emotion rather than adding it 9.
Build Quality★★★★★Unmatched level. Aluminum machining precision and finish beauty reach artisanal realm. M-Cast/M-Coat paint quality is perfect. Industrial product and simultaneously artwork satisfying ownership pleasure 5.
Price-to-Value★★★★☆Absolute amount is extremely expensive, but performance equals or surpasses speakers in double the price range 7. Offers flagship-level technology at strategic pricing, holding very high value in “ultra high-end” context.
Future-proofing / Repairability★★★★☆Robust construction assuming decades of use (new foam edges also tout long-term durability 12). Being passive type, immune to digital technology obsolescence. Support system is solid, but repair of 100+ kg enclosure is physically major.

Organizing Positive / Negative Elements

  • Strengths:
    • Transparency and detail reproduction capability like no other.
    • Vast dynamic range never breaking down regardless of volume.
    • Holographic soundfield reproduction where speaker presence disappears.
    • Artisan-level manufacturing quality through cutting-edge materials and processing technology.
    • “Vanishing” capability exposing recorded source truth.
  • Weaknesses:
    • Extremely demanding of upstream equipment and recording quality. Ruthlessly exposes system defects.
    • Difficult load demanding extremely high current supply capability from amplifiers.
    • Bass prioritizes “quality (speed/resolution)” over “quantity (impact),” potentially insufficient for those seeking impact.
    • Absolute price difficult for non-audiophiles to comprehend.

6. S3 Mk3 on the Coordinate Axis: Market Significance

Evaluating S3 Mk3 as merely a high-performance speaker is like missing the forest for the trees. Behind this product’s development lies Magico’s clear strategy to redraw the high-end market’s power map.

Previously, the ultra high-end market had a “price-no-object” flagship tier represented by Magico M9 and Wilson WAMM, and a “still very expensive” semi-top tier where the previous S3 Mk2 belonged. S3 Mk3, while inheriting M9 DNA strongly, significantly raised price from the old model, blurring the boundary between these two tiers. It’s like housing a “super-speaker” soul in a compact cabinet.

Magico throws down a challenge to the market by offering performance approaching M-series at around $50,000: “Is spending over $100,000 meaningful when 95% of that performance is available at this price?”

This exerts tremendous pressure on competitors like Wilson Audio and YG Acoustics. Their same-price-range models (Sasha V, Hailey 2.2) are now fated to be compared with speakers bearing direct $750,000 flagship technology. S3 Mk3’s emergence is a game-changer forcing reconsideration of value standards across the high-end market.

Sound Quality Strengths and Weaknesses (Competitive Comparison)

  • vs. Wilson Audio Sasha V:
    • Strengths: With sealed aluminum enclosure, S3 Mk3 likely holds advantage over Sasha V’s rear-ported composite material enclosure in transient response speed and enclosure coloration absence. Sharper sound onset, more analytical sound.
    • Weaknesses: Sasha V may have warmer, more “romantic” tonality and richer bass quantity characteristic of bass reflex type. This may appeal to some listeners.
  • vs. YG Acoustics Hailey 2.2:
    • Strengths: Closest design philosophy rival, also adopting sealed aluminum enclosure. S3 Mk3’s dual 9-inch large-diameter woofers potentially have advantage in bass drive force and scale sense against Hailey 2.2’s single 10.25-inch.
    • Weaknesses: Battle becomes driver material and crossover design philosophy differences. S3 Mk3’s graphene/carbon composite cone and YG’s machined aluminum BilletCore drivers will create subtle differences in tone and texture. Which is superior approaches preference territory.
  • vs. Rockport Technologies Avior II:
    • Strengths: Avior II is rear-ported, presumably with more room-filling powerful bass than S3 Mk3. However, S3 Mk3’s sealed-type bass is undoubtedly tighter, faster, clearer. Should win in pitch differentiation and rhythm accuracy.
    • Weaknesses: Bass “quality” (Magico) vs. “quantity” (Rockport) tradeoff. For pure impact or body-shaking sensation, Avior II may sound appealing in some scenes.
