Beyond the original factory: Mercedes-Benz S 450 uses Biwei Blue Core for secondary audio creation, demonstrating the art of dual-system acoustic superposition

For a car like Mercedes-Benz S 450, which symbolizes the ultimate luxury and craftsmanship, its original Berlin Sound audio system has undoubtedly stood at the top of the pyramid of car audio, providing drivers and passengers with far extraordinary listening enjoyment. However, in the eyes of true high-grade connoisseurs and music enthusiasts, the pursuit of “perfection” is endless. What they are eager for is to create a new peak above the top level and hear more subtle emotions in the grandeur. The subtlety and nobility of our customized audio upgrade scheme for S 450 this time lies in-We never replace or modify any of the original, carefully tuned Berlin Sound systems, but by installing a set of intelligent audio management hub-Vocal box–Achieve perfect compatibility and seamless switching between the original car system and the upgraded system. On this basis, we constructed a second set of composed ofJapan’s Biwei Blue Core top playback system, Feishi high-power amplifier and Biwei Red Core subwoofer unitComposed of an independent Hi-End sound system. This means that your car will have two sets of the world’s top sound systems at the same time: one is the original Mercedes-Benz Berlin sound, and the other is the Biwei-Feishi combination specially designed for the ultimate music restoration. The two legendary voices can be switched at will with one click, and all the intelligent functions, ambient lighting, and touch operation of the original car are as good as ever, truly achieving “distinguished upgrade, lossless experience”.

 

 

Ingenuity is minimal, and extraordinary craftsmanship is shown in every inch

 

1. A-pillar tweeter: the fusion of invisible art and precise acoustics

 

Tweeter adopts depthEmbedded cladding installation process, blending it perfectly into the curve of the A-pillar. Not only is it visually integrated with the high-grade nappa leather or wooden trim of the original car interior, without any trace of modification, but more importantly, through the precise calculation of the installation angle and depth, an accurate sound image positioning reference point is constructed for the entire front sound field, so that the position of each musical instrument and the mouth shape of the singer are in front of you.

2. Door panel speaker system: the ultimate unity of acoustic design and luxurious aesthetics

 

The midrange and midwoofer units in the door panel are by no means simple replacements. Based on the unique internal structure and shape of Mercedes-Benz S-Class doors,An exclusive acoustic box with a specific tilt angle is tailored for each speaker。 This design ensures that the sound wave points directly to the listener in the best path, greatly improving the direct sound ratio and clarity of the sound. Implementation of luminous mask and vehicle original factory ambient light systemIntelligent linkage, the light moves with the music. We insist on choosing the leather for covering the boxAlcantara or high-grade leather materials from the same origin as the original car interior, to achieve 100% harmony and unity in touch, color and texture.

3. Audio source core: blue label player, defining the highest standard of digital audio

 

The source of all good sounds is crucial. We equipped this system withThe “Blue Label” series of professional players symbolizing the highest specifications in the Biwei brand。 It adopts top-level digital audio architecture and ultra-low jitter clock system, which can extremely restore every detail and dynamic in music files, and lay a pure, full and high-resolution sound foundation for the whole sound system from the starting point of digital signal.

4. Trunk process layout: a majestic energy center under minimalist aesthetics

 

The modification of the rear trunk adheres to what the Mercedes-Benz S-Class should haveMinimalist Luxury Concept of “Form Follows Function”。 All devices are delicately laid out and organized, creating an efficient, stable and visually unobtrusive energy hub in a limited space:

 

• The source of surging low frequencies: Biwei Red Heart 8-inch subwoofer unit
• Precise energy drive: three Feishi power amplifiers (independently drive treble, mid-bass and subwoofer channels respectively)
• Pure power guarantee: Biwei professional power management and filtering system
• Decoding core: Biwei A 6 R HD audio decoder

► Acoustic black technology: the first music broadband · sub-bass maze acoustic cavity

 

In this upgrade, the most disruptive technical highlight isThe “labyrinth” subwoofer cabinet exclusively developed by Music Broadband Acoustics Laboratory and applied to this car。 The cabinet is specially designed for the physical characteristics of the Biwei Red Heart 8-inch subwoofer unit.

 

Its interior is not a traditional closed or inverted structure, but is laid outWinding channels calculated by supercomputer precision acoustic simulations。 Sound waves are guided, superimposed and extended in an orderly manner in the labyrinth channel, thus achieving two major breakthroughs: first, the effective dive depth and smoothness of low frequencies are greatly extended, making the bass sound deeper and more natural; Second, it significantly improves the energy conversion efficiency of the unit and outputs greater sound pressure with a smaller amplitude. This is equivalent to achievingThe amazing effectiveness of “one for two”–In the limited trunk space of S 450, only one 8-inch subwoofer can obtain the surging, clean and layered extremely low frequency effect that can only be created by two or more units under the traditional design. It is a perfect resonance between engineering mechanics, materials science and acoustic art.

 

► Dual system exclusive experience: one-click switching, two legendary voices

 

When all upgrades are successfully completed, your Mercedes-Benz S 450 will evolve into a “mobile music hall” with dual souls:

 

• Original car Berlin sound system: All functions are intact, and it is still a trustworthy luxurious background sound for your daily commuting and business pickup. It is easy to operate and authentic.
• Added Biwei-Feishi Hi-End system: When you want to focus on the music itself and pursue the ultimate emotional resonance and detail restoration, switch to this system with one click. It will present you with a studio mastering-level listening experience, whether it is the majestic dynamics of classical symphony or the subtle breath of jazz vocals.

 

Two sets of the world’s top sound systems coexist harmoniously in your car, and switch seamlessly through the intelligent vocal treasure box, so that you can choose the most suitable sound companion according to your mood and occasion every time you travel.

 

Top-level upgrade is never subversion, but transcendence and integration.This is not only a technical blessing for the sound system of Mercedes-Benz S 450, but also a perfect solution for “double luxury experience” for high-net-worth car owners. Witness the extraordinary craftsmanship in the details, and feel the ultimate pursuit in listening. We offer you this noble key to unlock the “palace-level twin voice”.
