Frequently Asked Questions about S2-Door Solution


How does the S2-Door Solution from Four Connect improve the sound quality of car speakers?

The S2-Door Solution significantly optimizes the sound quality of car speakers by using three materials: The 2.5 mm thick S2-Basemat (Alubutyl) effectively reduces resonances and vibrations of the door sheet metal, creating an extremely stable enclosure. Additionally, thermal insulation and sound damping are supported by a 6 mm thick S2-TopFlex layer made of high-quality closed-cell foam, which is directly glued to the S2-Basemat. Finally, the 7 mm thick S2-Softflex material, an absorption material, minimizes disturbing noises by being applied to the inside of the door panel. Together, this setup ensures improved bass reproduction and higher precision.

What materials are included in the S2-Door Solution set from Four Connect?

The S2-Door Solution set includes three specific materials: Alubutyl, known as 8x S2-Basemat, forms the foundation with a thickness of 2.5 mm to reduce resonances and vibrations. Furthermore, the set contains 2x S2-TopFlex, an insulating material made of high-quality closed-cell foam with a thickness of 6 mm, which achieves both thermal insulation and sound damping. Finally, the solution includes 4x S2-Softflex, a sound-absorbing absorber with a thickness of 7 mm that helps reduce disturbing noises. These materials are strategically combined to optimize the sound and stability of vehicle doors.

How is the S2-Door Solution from Four Connect installed in vehicles?

The installation of the S2-Door Solution first requires applying the 2.5 mm thick S2-Basemat mats directly to the door sheets to reduce vibrations. Next, the 6 mm thick S2-TopFlex layer, a closed-cell foam, is glued to the Basemat mats to ensure additional thermal insulation and sound damping. Finally, the 7 mm thick S2-Softflex absorbers are applied to the inside of the door panel to further eliminate disturbing noises. All components are easily cut to fit the door contours and exact dimensions of 500 x 370 mm, allowing for seamless integration.

What advantages does the S2-Door Solution from Four Connect offer in terms of driving comfort and efficiency?

The S2-Door Solution significantly improves driving comfort by minimizing external noise and the annoying rattling of the door panels. This is achieved through the effective reduction of resonances and vibrations using the 2.5 mm S2-Basemat and further damping effect thanks to the 6 mm thick S2-TopFlex inner layer. The 7 mm S2-Softflex complements this system with impressive sound absorption in the interior. Furthermore, efficiency has been optimized by perfectly coordinating these three materials, achieving an ideal, professional damping result for the described applications in vehicle doors.

What are the dimensions of the S2-Door Solution from Four Connect and how many mats does it contain?

The S2-Door Solution consists of a total of 14 mats. Each mat has dimensions of 500 x 370 mm. This set includes eight S2-Basemat mats, which are characterized by a thickness of 2.5 mm and are primarily used for resonance reduction. Additionally, two S2-TopFlex mats with a thickness of 6 mm are included, providing thermal insulation and sound damping. Four S2-Softflex mats with a thickness of 7 mm complete the set and are used for absorbing disturbing noises on the inside of the door panel. This precise sizing allows for elaborate adaptation to various door structures.

How does the S2-Door Solution from Four Connect affect resonance in the car door area?

The resonance influence of the S2-Door Solution primarily occurs through the 2.5 mm thick S2-Basemat mats made of Alubutyl, which effectively minimize resonances in the door area by absorbing vibrations in the material and stabilizing the door structure. This leads to a more stable sound environment and improves the overall impression of the provided acoustics. The combination of Basemat, TopFlex, and Softflex materials works synergistically to optimize their resonance control, with each component effectively addressing specific frequency ranges, thus creating a more harmonious sound image.

Which set materials of the S2-Door Solution provide thermal insulation and sound absorption?

The 6 mm thick S2-TopFlex products in the S2-Door Solution offer remarkable thermal insulation. Made from high-quality, closed-cell foam, they not only assist with temperature control but also provide additional sound damping by absorbing vibrations, which significantly contributes to the reduction of unwanted noise. Additionally, the 7 mm thick S2-Softflex materials act as powerful sound absorbers. These are strategically placed on the inside of the door panel to efficiently eliminate disturbing noises, greatly enhancing driving comfort.

Can all components of the S2-Door Solution be installed directly on top of each other?

Yes, the components of the S2-Door Solution are designed for sequential installation, ensuring maximum damping efficiency. The installation begins with the application of the 2.5 mm S2 base mat, which is glued directly to the bare door sheet to reduce vibrations. On top of this, the 6 mm thick S2 TopFlex layer is fixed, which, in addition to the base mat, provides thermal insulation and sound damping. The final layer is the 7 mm S2 Softflex, which is glued onto the already installed materials and completes the entire construction through effective sound absorption. This creates a comprehensive multi-layer system.

How is the vibration damping of the S2-Door Solution by Four Connect ensured?

The vibration damping provided by the S2-Door Solution is primarily ensured through the use of the 2.5 mm thick S2 base mat, an alubutyl product specifically designed to suppress door sheet vibrations. Due to its high density and adhesive properties, this material absorbs unwanted resonances and stabilizes the vehicle door structure. This results in fewer disturbing effects, leading to a significant improvement in audio quality. The stiffer door structure achieved reduces energy losses and contributes to a more powerful sound from the speakers.

Is the S2-Door Solution by Four Connect suitable for every vehicle model?

The S2-Door Solution is very adaptable due to its universal dimensions of 500 x 370 mm per mat and can be adjusted to various vehicle door models. It is excellent for vehicles that require additional acoustic insulation and sound absorption. However, since no specific car brands are mentioned in the product description, the application area should be manually checked before purchase. The best possible fit is ensured by the precise cutting options of the mats. In particularly complex door structures, a customizable installation and precise cutting may be required to ensure optimal performance.
