Acoustic remodeling of pure electric flagship | Tesla Model X is equipped with Rekal two-way system, using professional modification technology to unleash the potential of top sound quality

As the technical benchmark of pure electric luxury models, Tesla Model X’s highly integrated body structure and sophisticated and complex audio circuit system put forward unprecedented stringent requirements for the professionalism of audio modification.

 

Based on in-depth communication of car owners’ listening preferences and accurate grasp of budget scope, we have tailored a set of personalized configuration solutions that combine Hi-End-level sound quality pursuit with high system integration. The detailed list is as follows:

1. Audio source host: Keep the original car’s high-specification host and make full use of its excellent digital audio output quality

2. Audio processing core: Japan’s Biwei 8-channel DSP audio processor achieves accurate sound field remodeling and frequency management

3. The main force of the front sound field: German Rekal HL-C 6.2 two-way speaker set (predecessor Rainbow GL-C 6.2 technology inheritance)

4. Rear sound field assistance: China Magic Cube AN-165 two-way package speaker

5. Ultra-low frequency supplement: German zero point 8-inch subwoofer cabinet

6. Speaker driver: Magic Cube six-channel power amplifier (active frequency division is used to drive the front sound field and passive drive the rear sound field)

7. Dedicated bass driver: zero point two-channel power amplifier

8. Signal transmission cable: German Barney purple series professional audio cable

9. Acoustic environment treatment: entire vehicle Japanese Flute God sound insulation and noise reduction project

Next, we will give you a complete presentation of every technical detail and construction link of this high-end model audio upgrade through detailed graphic records.

 

Phase 1: Full vehicle acoustic environment optimization project

An excellent sound system is inseparable from a high-quality acoustic environment. We first perform a comprehensive sound insulation and noise reduction treatment on the vehicle. This is not only the basis for suppressing driving noise, but also the key to creating an ideal working environment for the horn unit.

At the beginning of construction, we systematically dismantled the entire interior parts of the vehicle to make full preparations for the precise pasting of sound insulation and shock-proof materials. Every snap, every wiring harness is professionally handled.

The first layer of high-quality shock-absorbing plate is constructed according to the scientific strip pasting process, which effectively suppresses the resonance of sheet metal and strengthens the rigidity of the body structure.

Then, a double layer of high-performance sound-absorbing cotton is laid to further absorb residual noise at medium and high frequencies and create a quiet listening space in the car.

Phase 2: In-depth modification of sound system

The removal of the original car horn unit reveals the general status of audio configuration of luxury models: despite the high pricing of vehicles, the speaker unit is often the same as that of mid-range models. This just shows that the core value of luxury car audio system lies more in its high-standard source host processing capabilities. Taking this Model X as an example, the sound decoding and output quality of its original host has been professionally evaluated to be equivalent to the level of an external 6,000-yuan professional host, which has laid an excellent foundation for our subsequent upgrades.

We noticed that the original horn base design of Model X contains unique acoustic considerations-its opening has a specific upward directivity, which is a precise design made by engineers to optimize the sound field in the car. In order to respect and utilize this original factory acoustic structure to the maximum extent, we decided to keep the original car horn base and tailored it with a high-precision adaptation gasket. This modification concept of “adapting to the car” is the key to realizing the potential of top-level equipment.

Construction begins with applying professional-grade sealant to the joints to ensure acoustic tightness and then securely bonding the custom gasket to the base.

The in-situ installation effect of the modified speaker base assembly achieves a perfect balance between non-destructive upgrade and acoustic optimization.

We strategically implanted a specific thickness of acoustic memory foam inside the base cavity. This subtle measure can effectively improve the acoustic resonance characteristics of the mid-frequency band, and bring audible improvements to the restoration, fullness and thickness of the human voice.

The Rekal mid-woofer unit is finally installed to complete the effect. This case once again proves that half of the value of top-notch car audio equipment lies in professional installation and adjustment. If you want to unleash its full potential, it is crucial to choose a modification team with profound technical background.

After precise angle adjustment, the tweeter is installed in situ on the A-pillar to ensure optimal high-frequency diffusion and sound field positioning.

The “brain” and “heart” of the system-Biwei DSP processor, Magic Cube six-channel power amplifier and zero-point bass power amplifier are integrated under the main driver’s seat. The layout is neat and the heat dissipation is scientific, which is convenient for subsequent maintenance and adjustment.

The zero-point 8-inch subwoofer cabinet is cleverly placed in the reserved space of the trunk, which provides deep and accurate low-frequency response while maximizing the practicality of the storage function.

At this point, the in-depth sound system upgrade project of this Tesla Model X has been completed. Every link embodies our respect for acoustic principles, our demand for modification technology and our commitment to the final sound quality performance.
