THE STUDIO LISTENING LIBRARY VSX CHEAT SHEET Know the speaker. Hear the room. The histories, acoustic decisions and listening signatures behind every VSX perspective - written for people who mix records, not people who collect presets. 46 LISTENING PERSPECTIVES / 26 ENVIRONMENTS VSX CHEAT SHEET INTRODUCTION 02 01 / THE PREMISE A room is not an equalizer. An engineer does not learn a monitor by memorizing its frequency curve. The useful knowledge is richer: how quickly the cabinet stops moving after a kick, how the upper mids describe a vocal, how the room changes apparent bass weight, and which familiar records still feel right at a low level. The best room is not the one that makes everything sound expensive. It is the one whose voice you know well enough to separate a speaker characteristic from a problem in the music. VSX gives that learning process an unusual range: purpose-built nearfields, large control rooms, mastering positions, cars, clubs and personal playback, all available without physically moving the session. WHAT THIS BOOK TEACHES Every room chapter starts with the monitoring philosophy. Every speaker entry explains the design and the resulting listening language, then closes with a single useful decision to carry back into a mix. There are no preset rankings, no magic EQ numbers, and no substitutes for hearing reference music. VSX CHEAT SHEET LISTENING PHYSICS 03 02 / HOW THE CHAIN WORKS The sound you hear has more than one author. 01 THE LOUDSPEAKER Driver materials, crossover choices, cabinet loading, waveguides, distortion and directivity decide what leaves the cabinet. A three-way ATC and an NS-10 are different instruments before they enter a room. 02 THE ROOM Position, boundaries, absorption, reflections and the listening seat change the result. A controlled nearfield and a farfield in the same control room reveal different aspects of the same mix. 03 THE RENDERER AND EAR VSX recreates a spatial listening perspective through a headphone-specific chain. The software state, headphone calibration, fit and listener all affect the final presentation. A waveform captured at the plugin output is not an individual eardrum measurement. VSX CHEAT SHEET LISTENING LANGUAGE 04 03 / HEAR THE DIFFERENCE What engineers mean when they describe sound. ATTACK The initial rise of a transient. A hard attack can be short and precise without being loud. DECAY How a note or space continues after the hit. Driver alignment and room reflections can lengthen what seems to be in the mix. GRIP A useful informal word for bass pitch, timing and level remaining distinct instead of turning into one low-frequency mass. LOW-MID MUD Overlap around bass harmonics, body of instruments and room warmth, usually heard as a loss of separation rather than a single bad frequency. PRESENCE How near a vocal or instrument feels in the upper-mid band; not synonymous with excessive brightness. AIR A sense of extension and openness at the very top; a signal can have plenty of air and still be harsh lower down. IMAGING The apparent placement of sound between or beyond the speakers. Controlled radiation and room symmetry matter. DEPTH Front-to-back placement shaped by direct/reverberant relationships, level, timbre and timing.

Its design brief is unusually clear: reduce the room contribution so balance, compression, vocal level and effects remain exposed. It places three very different monitoring philosophies into the same deliberately restrained setting. The point is not that dryness equals accuracy; it is that less apparent ambience can make small decisions less comfortable to ignore. COMMUNITY SUMMARY Desert brings the mix closer. Compared with Spitfire, its bass has been described as tighter and its presence more forward; the Kii view has drawn particular praise for precision. The attraction is not sheer scale but a sense of less space between the monitor and the arrangement. It invites close attention to kick definition, vocal placement and the edges of layered instruments, without asking the room to make the music feel bigger. ROOM PERSPECTIVE The most revealing room is not necessarily the room with the least acoustic energy. Here, dryness is a design choice: it reduces how much the listening space romanticizes a vocal tail or gives a thin arrangement borrowed warmth. 01 ProAc Studio 100 NEAR-FIELD The work is in the middle A passive two-way with a treated-cone mid/bass driver and soft-dome tweeter. Rather than a managed DSP system, it depends on its driver integration, amplifier and placement. The compact format places natural limits on bass authority but makes the vocal-to-instrument relationship its most interesting territory. Listen to how the lead sits against layered samples, guitars and pads. The useful impression is not “bright” or “dark” in isolation; it is whether consonants, harmonics and arrangement density remain distinct without the room filling in the gaps. IN PRACTICE If the mix seems thin, compare a known record first. A small passive nearfield should not be asked to supply the physical scale of a farfield. 02 ATC SCM25 NEAR-FIELD The midband that does not blur The SCM25A is an active three-way built around ATC’s three-inch soft-dome midrange. Crossovers around 380 Hz and 3.5 kHz leave most of the vocal fundamentals and presence region to one driver, keeping low-frequency excursion away from that work. That separation of duties supports unusually transparent mids, low distortion and stable imaging. Its revealing quality is less about a hyped presence region than the ease of following small dynamic changes: a compressor beginning to grip a vocal, low-mid bloom around a guitar, the difference between a kick’s transient and its tail. IN PRACTICE Clean bass can tempt you to add too much. Judge the note shape here, then judge its relative weight on a familiar full-range anchor. VSX CHEAT SHEET LISTENING PERSPECTIVE 07 03 / NEAR-FIELD Desert Studios Kii THREE Clarity by controlling the room DESIGN SOUND Kii’s multiple low-frequency drivers and delay-based active control reduce rearward bass radiation. The physical system therefore launches less destructive energy toward the front wall than many conventional speakers. This controlled directivity is central to the separation and imaging heard from the physical system. The distinctive idea is not merely a flat response. When early reflected energy is reduced, spatial details can become easier to follow: reverb pre-delay, doubled vocals, opposing synth layers and low-mid buildup. ACTIVE DRIVER CONTROL LOWER REAR RADIATION CLEANER EARLY ARRIVAL WHAT THE ENGINEERING CHANGES Cardioid control matters before any equalizer enters the discussion. Preventing some energy from striking the wall immediately behind the cabinet reduces a source of time-delayed low-mid contamination. THREE-SPEAKER RELATIONSHIP 01 ProAc Studio 100 / The work is in the middle 02 ATC SCM25 / The midband that does not blur 03 Kii THREE / Clarity by controlling the room IN PRACTICE Use the apparent clarity to investigate masking; do not assume a wide stereo image is phase-safe without a separate mono check. VSX CHEAT SHEET ACOUSTICS / PRACTICE 08 ENGINEERING NOTE WHY THE ROOM MATTERS The first reflection is part of the tonal balance When a conventional loudspeaker launches bass toward a nearby wall, part of that sound returns to the listener after a short delay. Depending on wavelength and distance, the returning energy reinforces or cancels the direct arrival. Equalizing the on-axis loudspeaker does not erase that timing problem. Controlled-directivity designs such as the Kii THREE reduce some of the backward radiation before it reaches the wall. A deliberately dry nearfield presentation, meanwhile, reduces the room’s apparent contribution by a different route. Both approaches seek a cleaner view of the recording, but they arrive there through different physical choices. In a mix, this distinction changes what the word “muddy” means. It might describe too much sustained energy in the arrangement, a long envelope on the bass instrument, or a room that makes perfectly well-balanced notes blend together. Use familiar commercial records to learn the sound of the listening perspective before turning that impression into an EQ move. VSX CHEAT SHEET ROOM STUDY 02 09 02 / 3 LISTENING VIEWS Spitfire Studios Warren Huart’s working room Spitfire is the working mix environment associated with Warren Huart, not simply a collection of expensive boxes. Its modern Los Angeles facility has documented Jay Kaufman design lineage and an Audient ASP4816 Heritage console. The Wayne Jones, Genelec and Kali choices form a hierarchy: hear scale, establish spatial relationships, then ask whether the record communicates without the privileges of a large system. They are three different methods of judging the same arrangement. COMMUNITY SUMMARY Spitfire's most striking impression is space. In VSX 8, its image has felt so externalized that the speakers seem to stand beyond the headphones. That changes how a listener experiences panning, ambience and the distance between a lead and its surroundings. Spitfire can make a production feel like an event unfolding in front of you, even for engineers who eventually choose another room as their daily tonal reference. ROOM PERSPECTIVE Huart’s published account is specific: his Genelec 8351s do most of the daily mix work; the Wayne Jones mains provide powerful playback and tracking; and the Kalis expose the ordinary small-speaker compromises. That hierarchy is the story of the room. 04 Wayne Jones mains FAR-FIELD MAIN Scale without losing the record Wayne Jones Audio builds high-powered active studio monitors with DSP-controlled alignment and dedicated amplifier channels. At Spitfire, Warren Huart uses his Wayne Jones mains for powerful tracking and playback, while the Genelec 8351s carry most of his mixing. The useful engineering idea is abundant amplifier headroom and controlled low-frequency reproduction: weight without needing the monitoring system to strain. The main-system role in Huart’s room is unmistakable: hear the complete arrangement at meaningful scale, including the body of the kick, the weight of the bass and the projection of the lead. Contrast that sense of effortlessness with the smaller speakers in the same room. IN PRACTICE A satisfying low end here is the beginning of a translation check, not the final answer. 05 Genelec 8351 MIDFIELD Geometry before glamour Genelec’s 8351A uses an acoustically coaxial three-way design: a concentric mid/tweeter, a broad front waveguide and concealed low-frequency drivers. Its controlled dispersion is as important to its stereo precision as its frequency balance. Sound On Sound described an unusually solid phantom centre and informative bass. This is a useful image for hearing a phantom centre, the width of a stereo synth, and whether a doubled line feels attached to or detached from its lead. The point of coaxial geometry is stable spatial information, not a permanent boost to any one frequency. IN PRACTICE If a stereo decision changes radically on the Kalis, determine whether the arrangement or the monitoring geometry is causing the disagreement. VSX CHEAT SHEET LISTENING PERSPECTIVE 10 06 / NEAR-FIELD Spitfire Studios Kali LP-6 The small-system reality check DESIGN SOUND The LP-6 is a front-ported active two-way with a six-and-a-half-inch woofer, soft-dome tweeter and waveguide. Its smooth mids and highs and convincing stereo placement are strengths, while deep-bass authority remains limited by cabinet size. A well-balanced record should still have a legible vocal, snare definition and recognisable bass movement through this size of monitor. Expect lower sub-bass authority, not necessarily missing bass information above the fundamental. TWEETER WAVEGUIDE CONTROLLED RADIATION RELIABLE MIDRANGE VIEW WHAT THE ENGINEERING CHANGES The waveguide helps the direct sound and room reflections share a more consistent spectrum. It does not turn a compact nearfield into a full-range speaker; those are separate engineering achievements. THREE-SPEAKER RELATIONSHIP 01 Wayne Jones mains / Scale without losing the record 02 Genelec 8351 / Geometry before glamour 03 Kali LP-6 / The small-system reality check IN PRACTICE If the 808 goes quiet while the beat remains clear, examine its audible harmonics before increasing sub energy. VSX CHEAT SHEET ACOUSTICS / PRACTICE 11 ENGINEERING NOTE THE SPITFIRE TRIANGLE One studio. Three jobs. A revealing hierarchy. Warren Huart’s account of Spitfire is unusually useful because it distinguishes the daily mix reference from the impressive playback system. He says the Genelec 8351s are where he spends most of his mixing time. Their coaxial geometry and broad waveguide give the phantom centre a stable anchor; they are speakers on which a small change in balance is easy to follow. The Wayne Jones mains are the system for tracking, full-range perspective and high-impact playback. Their power tells the story of the whole arrangement at scale. The Kali LP-6s bring the music back to a smaller and more ordinary monitor. Those roles explain why a producer can prefer the Genelec while still being moved by the mains. A spectacular playback system may reveal bass authority; a smaller speaker can tell you whether the hook survives without that authority. The question is not which one wins. It is whether you recognize the same artistic intention on all three. VSX CHEAT SHEET ROOM STUDY 03 12 03 / 2 LISTENING VIEWS Zuma Studios Range without spectacle Zuma’s published identity is a private Southern California room built around an ADAM S3H/sub arrangement and ATC farfields. That pairing is more interesting than the room’s equipment budget: the horizontal three-way ADAM offers a tight working view; the larger ATC gives low-frequency scale and dynamic ease. Read it as a near-to-far perspective change, not a contest over which system sounds better. ROOM PERSPECTIVE The distinction here is the distance at which the music is heard. Midfield decisions often concern timing, image and the seams of an arrangement; a larger ATC system makes the distribution of power and bass headroom more apparent. 07 ADAM S3H + sub MIDFIELD Transient shape and spectral reach The S3H places two seven-inch low-frequency drivers beside a dedicated midrange and ADAM’s S-ART folded-ribbon tweeter. This horizontal three-way is designed for a broad, articulate working view; the sub adds energy below the cabinet’s natural working range. Its value is following the edges of an arrangement: attack and decay of percussion, brightness without splash, and the point where saturated synths begin to mask lead elements. The crossover and sub alignment matter to how continuous that presentation feels. IN PRACTICE When a kick feels oversized here, decide whether the issue is transient level, sustained bass or the sub integration before touching EQ. 08 ATC SCM110ASL Pro FAR-FIELD Dynamics at a larger scale The SCM110ASL family takes ATC’s controlled three-way philosophy into a larger enclosure with serious headroom. The soft-dome midrange remains the identifying component; scale comes from the bass system’s lower distortion and ease at higher output. The attraction is hearing the mix breathe without the loudspeaker seeming to struggle. Compare a dense chorus with the ADAM: do vocals stay present when the low end opens up, and does the drum envelope retain shape as the energy rises? IN PRACTICE A large clean system may make every low note sound impressive; separate consistency from sheer impact. VSX CHEAT SHEET ROOM STUDY 04 13 04 / 3 LISTENING VIEWS Yellow Matter Studios Three approaches to control Yellow Matter places a traditional compact reference, a classic Genelec and a low-frequency-directivity design in one virtual setting. They approach neutrality differently: Neumann through tightly controlled conventional engineering, Genelec through active calibration and response consistency, Kii through the radiation pattern itself. A change between them is a lesson in how room interaction can alter the sensation of separation. COMMUNITY SUMMARY Yellow Matter's farfield can sound thicker through the low mids than other large-system views. That weight brings bass, guitar body and vocal warmth into closer company. At this scale, fullness and congestion sit side by side: a mix can gain authority while losing separation. The question is whether the arrangement stays intelligible inside that weight, not whether every monitor should sound equally lean. ROOM PERSPECTIVE Three radically different kinds of monitor share one virtual listening environment. Listen to their different driver geometries: a compact controlled-directivity Neumann, a conventional large Genelec nearfield and the Kii’s actively focused low end. 09 Neumann KH120 NEAR-FIELD A compact definition of neutrality The original Neumann KH120A is a compact active two-way with a cast-aluminium enclosure, a mathematically developed waveguide and carefully managed off-axis response. Vertical control reduces desk-reflection interference, while its neutral midrange provides a stable view of vocals and small transient detail. The useful language here is proportion: whether the vocal is the right size, whether reverberation clouds the midrange and whether the rhythm survives when the deepest bass no longer dominates. IN PRACTICE Do not increase 30 Hz because a compact two-way cannot reproduce it as a large system does. 10 Genelec 1032C MIDFIELD Classic monitoring with modern control The 1032 lineage pairs a strong conventional two-way sound with Genelec’s waveguide engineering; the C generation adds contemporary digital management. Its physical identity is different from the coaxial 8351 and should not be described using the same imaging mechanism. Expect a direct professional listening perspective: solid kick attack, clear upper-mid information and an image that can show the relationship between the vocal and loud guitars or synths without pretending to be a huge farfield. IN PRACTICE Use the Kii alongside it to hear how changes in directivity and room interaction reshape low-mid clarity. VSX CHEAT SHEET LISTENING PERSPECTIVE 14 11 / FAR-FIELD Yellow Matter Studios Kii THREE The same architecture in another room DESIGN SOUND The active, rearward-attenuating bass design is the same Kii philosophy encountered in Desert. Yellow Matter, however, contributes a different room rendering, model state and possibly setup. Two nominally identical speaker names do not make a controlled room-only experiment. What is useful is the comparison itself: if a reverb tail or bass boundary feels different here, note the combined system difference rather than calling either view the “true Kii” response. ACTIVE LOW-FREQUENCY FOCUS ROOM BOUNDARY RESPONSE SPATIAL SEPARATION WHAT THE ENGINEERING CHANGES Hear the Kii here as a different complete speaker-room system from Desert, not merely a duplicate product. In a studio, placement and nearby boundaries still shape what controlled directivity can accomplish. THREE-SPEAKER RELATIONSHIP 01 Neumann KH120 / A compact definition of neutrality 02 Genelec 1032C / Classic monitoring with modern control 03 Kii THREE / The same architecture in another room IN PRACTICE Keep one version and one listening level fixed when learning the two Kii perspectives. VSX CHEAT SHEET ROOM STUDY 05 15 05 / 3 LISTENING VIEWS NRG Studio C An actual studio with several eras Studio C is an unusually identifiable physical space: a Gothic Revival control room at NRG Recording Studios in North Hollywood. The 1998 opening system and the later Ocean Way installation are not the same rig. The room’s size, architecture and evolving hardware explain why a studio’s sound is a history, not a static brand label. In VSX, move between the smaller checks and the mains without assuming their differences are solely caused by speaker frequency response. COMMUNITY SUMMARY NRG's midfields made a strong impression on the arrival of VSX 8, earning a place as a new daily reference. The appeal of a midfield view is perspective: enough scale to hear the production as a whole, while the vocal and the body of the instruments remain central to the picture. Here, the interesting decisions are relational: how drums support the lead, how guitars occupy the low mids, and whether ambience adds depth or density. ROOM PERSPECTIVE Studio C has a documented history and physical identity independent of VSX. Its Gothic control-room architecture and evolving monitoring chain are a reminder that studio sound is something built, maintained and changed, not a factory setting. 12 Yamaha NS-10 + sub NEAR-FIELD The midrange with its bottom restored The NS-10 became a studio language through familiarity and a revealing, limited working bandwidth rather than extended bass or cosmetic smoothness. Adding a sub changes that classic relationship: low-frequency information becomes available, but the integration depends on crossover, level and phase. The essential NS-10 question remains whether the lead, snare, guitars and vocal articulation coexist in the forward band. The additional sub makes kick-to-bass proportion audible in a way the unaided NS-10 cannot. IN PRACTICE Do not interpret a change at the crossover as a vocal or bass arrangement fault without another system. 13 ATC SCM25 MIDFIELD The same dome, a different studio The SCM25’s dedicated soft-dome midrange and low-distortion three-way architecture are preserved as a design identity, but NRG’s simulated control room supplies another acoustic frame. It is a mistake to assume that the same cabinet makes its perceived sound identical to Desert. Here the interesting variable is how the same kind of precision feels in a more characterful listening environment: sibilance, low-mid thickness and front-to-back focus may be judged differently even when the loudspeaker family has not changed. IN PRACTICE Compare the same commercial reference in both ATC views before compensating for an apparent tonal change. VSX CHEAT SHEET LISTENING PERSPECTIVE 16 14 / FAR-FIELD NRG Studio C Ocean Way HR3.5 + sub A room-scale instrument DESIGN SOUND The HR3.5 is a large Ocean Way horn-based main-monitor architecture, associated with controlled high output and low distortion. Its horn and waveguide system directs energy with a different geometry from conventional nearfields; the main system also reaches the low frequencies with substantial authority. The experience to learn is projection: an aggressive vocal should remain defined at scale, dense drums should not collapse into a wall, and a mix should feel large without its lower mids becoming soft or indistinct. LARGE MAIN SYSTEM MORE ACOUSTIC HEADROOM FULL-SCALE MIX VIEW WHAT THE ENGINEERING CHANGES A main monitor changes the mix’s perceived size as much as its measured bandwidth. Do not mistake physical scale for more information: the nearfield can expose faults the full-range rig makes pleasant. THREE-SPEAKER RELATIONSHIP 01 Yamaha NS-10 + sub / The midrange with its bottom restored 02 ATC SCM25 / The same dome, a different studio 03 Ocean Way HR3.5 + sub / A room-scale instrument IN PRACTICE Large-room power is a context. Confirm precise balance changes at nearfield scale. VSX CHEAT SHEET ACOUSTICS / PRACTICE 17 ENGINEERING NOTE A STUDIO WITH A HISTORY NRG Studio C is not an interchangeable preset A control room has a history of physical alterations, engineering choices and changing monitoring systems. NRG Studio C is identifiable by its Gothic-influenced architectural treatment, the surrounding facility’s long Los Angeles history, and the large Ocean Way system associated with the room. Smaller Yamaha and ATC references give the engineer a second and third scale of judgment. This is how real rooms work: a large monitor reveals power; the close loudspeaker makes the decision intimate; a familiar mid-field bridges them. When you hear these differences in VSX, you are hearing distinct modeled listening chains. Their variation is musically useful even if it cannot be reduced to a single “room curve.” Soundstage, bass decay, vocal presence and apparent loudness are all properties of the combined reference. Learn the chain as a recognizable place rather than an anonymous frequency plot. VSX CHEAT SHEET ROOM STUDY 06 18 06 / 3 LISTENING VIEWS Archon Studio A three-distance listening philosophy Producer Aris Archontis’ private room pairs Amphion nearfields, ATC SCM150 midfields and Pelonis Signature farfields. Distance here is not cosmetic. At the near position, the arrangement and vocal envelope dominate; further back, dynamic density and bass scale come forward. The larger systems are also more vulnerable to a mixer confusing satisfying physical weight with an objectively correct bass balance. COMMUNITY SUMMARY Archon mids have become a working favorite. Listeners favor them as a main reference, including a move from Spitfire after VSX 7. Yet returning after time away can make their balance feel unfamiliar. That tension captures the value of a monitor you know: it becomes a dependable frame for vocal level, snare weight and low-mid balance. Familiarity turns a perspective into a working instrument. ROOM PERSPECTIVE Archon’s ladder from small Amphion to ATC midfields to Pelonis mains is especially useful as a study of scale. A mix can feel completely organized nearby and still require a second judgment when the speakers move serious air. 15 Amphion One15 + sub NEAR-FIELD Communication over spectacle Amphion’s passive two-way designs use a carefully shaped tweeter waveguide and a passive-radiator bass alignment. The physical One15 keeps the midrange communicative without needing excessive presence; its modest bass extension is part of that compact design. The sub in Archon adds the low end that the compact cabinet does not supply unaided. The nearfield still teaches the arrangement: is the bass line following the groove, are vocals intelligible, and do midrange instruments fight for the same attention? IN PRACTICE A sub that sounds slightly disconnected points to monitoring integration as one possible cause, not automatically a bad kick or 808. 16 ATC SCM150 MIDFIELD Big midrange, honest scale The SCM150 is a large active three-way built around ATC’s celebrated soft-dome midrange and substantially greater bass capability than the SCM25. The underlying aim is familiar ATC: strong linearity and dynamics without relying on elevated distortion to produce excitement. The revealing quality is low-mid structure at real volume. When distorted synth bass and guitars overlap, can the listener separate harmonic density from actual bass weight? Is the lead still centered when the arrangement is loud? IN PRACTICE Use the nearfields to test whether the mix’s intelligibility depends on the big speaker’s physical scale. VSX CHEAT SHEET LISTENING PERSPECTIVE 19 17 / FAR-FIELD Archon Studio Pelonis Signature 215AW Farfield scale and point-source thinking DESIGN SOUND The Pelonis Signature 215AW is a custom, large dual-concentric-style farfield identified with Archon’s system. Detailed public acoustic specifications are scarce; the important verified facts are its intended farfield role and the presence of this specific main-monitor system in the studio inventory. At the far seat, low-frequency energy, apparent depth and overall pressure can dominate perception. Learn the sensation of width and weight here as a separate judgement from the articulation heard on the Amphions and ATCs. MAIN MONITOR GEOMETRY HIGH-LEVEL LISTENING SCALE AND PROJECTION WHAT THE ENGINEERING CHANGES The Pelonis is an installed main-system perspective rather than a generic commercial reference. Its useful lesson is how a familiar engineer chooses between nearby detail and the authority of a larger system. THREE-SPEAKER RELATIONSHIP 01 Amphion One15 + sub / Communication over spectacle 02 ATC SCM150 / Big midrange, honest scale 03 Pelonis Signature 215AW / Farfield scale and point-source thinking IN PRACTICE If a mix sounds cinematic here but loses its center on the smaller views, scale is flattering an imbalance. VSX CHEAT SHEET ACOUSTICS / PRACTICE 20 ENGINEERING NOTE THREE SIZES OF TRUTH What a monitor ladder tells the ear Archon moves from a small Amphion nearfield to an ATC SCM150 midfield and then a Pelonis main system. The design choices ask three different questions. The Amphion uses a pronounced waveguide and compact bass driver to keep directivity controlled while exposing the musical middle. The much larger ATC supplies a dedicated midrange and increased dynamic headroom, allowing a dense production to remain legible at a level that would strain a small loudspeaker. The Pelonis completes the move toward the scale of a main system. A useful listening habit is to change scale without changing the artistic goal. Does the chorus remain intimate when the physical size grows? Does the low-frequency arrangement gain authority without swallowing its harmonic rhythm? More bass bandwidth should provide information, not force an automatic bass cut.
