Audi Q 5 L acoustic remodeling plan: awaken mobile concert halls with Dynaudio’s ultimate three-way frequency

1. Prologue: One sword in nine years, the return and reconstruction of Dynaudio’s flagship

 

After nine years of precipitation and expectation, Dynaudio, a Danish palace-class audio brand, brings its treasure-ESOTAR top-of-the-line Isota three-way speaker systemReturn to the top modification matrix of music broadband as the king! The carrier of this project is the third benchmark sound system carried by the Audi Q 5 L model car (its evolution process: Biwei → Feishi → Dynaudio), which marks another step in our exploration of sound art. reached a new level. The core philosophy of the whole modification project always revolves around the ultimate proposition of reproducing the original sound. From the unsealing inspection of equipment, to the precise construction of every acoustic structure, to the final systematic adjustment, the whole process profoundly interprets the irrefutable truth of the car audio modification industry:“Top-level equipment is only a’semi-finished product ‘, and the matching top-level modification technology is the’other half’ that turns it into gold.”

Extraordinary right out of the box:

 

 

The new genuine Dynaudio ESOTAR series units are quietly displayed: the tweeter unit, with its extremely accurate silk film dome technology, indicates the ultimate detail restoration; The mid-range unit adopts lightweight high-tech diaphragm, which lays a solid foundation for the mid-range of human voice and musical instruments; The mid-bass unit relies on its signature large dynamic MSP magnesium silicate composite sound basin, waiting for the burst of surging energy. Even if it has not been powered on for audition, its exquisite craftsmanship and materials have fully demonstrated the extraordinary aura and profound heritage of flagship products.

 

 

2. In-depth analysis of core technologies: building a dual palace of visual aesthetics and auditory science

 

1. A-pillar independent acoustic box · split installation process-a co-evolution of vision and hearing

 

 

Directional Acoustic Magic: The treble and midrange units are not simply fixed, but are based on the precise sitting posture of the main driver’s seat “emperor’s seat”Millimeter-level positioning in three-dimensional space。 We use the professional SAG acoustic analysis system to calculate and give each unit the best tilt and horizontal angle, aiming to accurately reconstruct the open, natural and rich stereo field like a “small concert scene” in this limited space in the car. As for the middle and bass unit, its working characteristics depend more on the scientificity of the box volume, so it is firmly placed in the precisely calculated independent box of the door panel without complicated directivity adjustment.

Advantages of forward-looking process: The A-pillar box used this time is originalAdjustable design, even after completion, the angle can still be fine-tuned without loss according to the owner’s subtle listening preferences, without the need to disassemble the interior, which greatly improves the plasticity and humanization of the system. The surface of the box is covered with carbon fiber texture material, and its texture and color are highly harmonious with the original interior style of Audi Q 5 L, achieving the perfect integration of acoustic function and visual aesthetics.

 

 

 

2. Reshape the triple dimensions of the car listening experience

 

Vocal performance dimension- Mellow and full, the emotional transmission is natural and real, and the microscopic details of the singer’s lips and teeth opening and closing, and the breath transformation are clearly discernible. It’s like being in a private recording studio, and there is no gap between the listener and the singer.

 

 

Sound field construction dimensions- The width, depth and height have been scientifically expanded, and the positioning of the instrument is accurate as if it was suspended in front of the eyes, with extremely high levels of separation, which faithfully restores the spatial information and on-the-spot atmosphere in the original recording.

 

 

Dynamic response dimension- Whether it is a gentle solo passage or a symphony orchestra’s climax, the system can lift weights easily, retract and release energy freely, and still maintain the stable performance of zero distortion and zero compression under the big dynamic impact, taking it easy and leisurely.

 

 

 

3. Door panel box modification: a data-driven mobile acoustic engineering art

 

The modification of the cabinet inside the door can be called the most challenging “mobile acoustic project” in the field of car audio. Its goal is to create an ideal working environment for the speaker unit with precise volume, good sealing and sufficient rigidity close to home Hi-Fi speakers in an irregular, multi-cavity and vibration-filled door space. This can by no means be accomplished by “experience” or “feeling”. It extremely tests the modification technician’s understanding of acoustic principles and the ability of precise construction.

 

Prerequisite for scientific modification: Must rely on professional acoustic measurement and analysis equipment.

 

Data construction process: We passSAG Acoustic Analysis System, accurately obtain the physical data of the interior space of the door, and combine it with various Thiele-Small parameters of the Dynaudio ESOTAR unit to conduct rigorous mathematical modeling and simulation calculations to ensure that the customized box body is in volume and phase conduction design (if applicable) It best matches the unit characteristics and completely abandons the traditional “guessing based on experience” mode.

The mystery of the final realization: After such a scientific transformation, the door panel box can be put down in high-power and dynamic music, effectively suppressing harmful box resonance and sound dyeing, and providing pure, solid and layered medium and low frequency response. Its sound cleanliness and control are comparable to high-end home Hi-End sound systems.

All this for one goal: to listen to the purest and uncompromised original Dynaudio sound. This also reveals the “love-hate” nature of the Dynaudio brand-loving its unparalleled potential and hating its almost demanding requirements for driving and tuning.

 

 

4. Core technology eggs: Why does the same set of Dynaudio 372 produce a world of different listening experiences?

 

Music Broadband clearly reveals the core of the problem through intuitive comparative test videos:

 

 

Case A (typical results for ordinary tuning shops): The sound field feels narrow and depressed, there is obvious depression in the mid-frequency band, and the overall listening experience is dry and unbalanced. The reason is often that the pointing angle of the unit is set incorrectly, and the whole installation and debugging process lacks objective acoustic data testing and guidance, which is entirely based on subjective experience.

 

 

Case B (Music Broadband Standard Construction Results): The sound field is open and natural, the high, medium and low frequency energy distribution is balanced, and the transition is smooth. This is entirely due toFull Data Support of SAG Acoustic Analysis System, and precise frequency division point setting and delay adjustment based on acoustic principles such as the “golden ratio”.
This is the root cause of Dynaudio’s “love-hate” relationship among many car owners: its excellent hardware potential is in huge contrast with its strict requirements for the depth of supporting technologies. The essence of top speakers is still a “semi-finished product”, and the awakening of its soul and the exertion of its ultimate performance depend 100% on the technical system and engineering practice behind it.

 

 

5. A rational choice guide for car owners: professional advice on music broadband

 

1. Be wary of “equipment-only stacking theory”: Top-class hardware is just a ticket to a good voice, not a guarantee. It is necessary to examine whether the tuning shop has the matching tuning technology, measuring equipment and success stories.

 

 

2. Adhere to the “scientific verification principle”: When choosing a modification service provider, you should actively ask the other party to show key linksObjective acoustic test data report(such as frequency response curves, phase consistency, harmonic distortion, etc. generated by SAG systems), use data to speak for itself instead of relying solely on verbal promises.

 

 

3. Conduct “Ultimate Dynamic Audition”: Final acceptance audition, please don’t limit yourself to simple pop songs. Be sure to test complex songs such as large-scale symphonies and high-quality LIVE LIVE recordings, and focus on testing the control, separation and confusion and distortion of the system when it is dynamic and multi-instrumental unison. This is the touchstone to measure the real strength of a system.

 

Technology is the second language in which sound can be accurately shaped and conveyed. It makes art measurable, reproducible and perfect.

 

 

Music broadband always takes science as the yardstick and technology as the cornerstone, constantly exploring and reshaping the cognitive boundaries and possibility limits of high-end car audio.
