Biwei’s all-round unit makes a shocking debut, and one unit can easily control mid-mounted, surround and treble!

In the increasingly complex collocation and integration trend of car audio systems, we have ushered in a revolutionary solution that returns to purity and simplifies complexity. Music Broadband is honored to announce,Japan’s BEWITH new generation full-range speaker unit is now officially available。 With its subversive design concept of “one unit, multi-purpose”, this product aims to completely change the traditional multi-unit and multi-amplifier complex system architecture, and provide car owners who pursue the ultimate simplicity and excellent sound quality with a new possibility to create an immersive car hearing feast.

█ One unit, three scenarios: redefining the logic of the sound field layout in the car
Traditional audio upgrades require the selection of different types of speakers for different locations and functions, but the core innovation of Biwei’s full-range unit lies in its excellent scene adaptability:
• As a center channel:Its wide frequency response range (500 Hz-20 kHz) perfectly covers the core frequency bands of human vocals and core musical instruments. When it is installed in the instrument panel, it can clearly anchor the vocals in movie dialogues, navigation voices and music in the center of the sound field. The actual measurement can improve the clarity and intelligibility of vocal dialogues by up to 60%, which greatly enhances the focus and realism of the sound field.
• As a surround channel:With its ultra-wide sound wave diffusion directivity characteristics, when installed in the rear sound field or rear surround position, it can effectively create a three-dimensional sound field with a sense of surrounding and spatial depth, making passengers feel as if they were in a concert hall or cinema. Get an immersive listening experience.
• Replace traditional tweeters:In the common two-way system, “faults” or “depressions” often appear at the frequency junction between the treble and midwoofer units. Use a Biwei full-band unit to directly replace the original car tweeter. It can rely on its full-band coverage capability,Connect low and medium frequencies smoothly and seamlessly, fundamentally solve this acoustic problem and make human voices fuller and more natural.

█ Five core technological breakthroughs lay the foundation for excellent sound
1. Ultra-wide all-round frequency response:It has a wide frequency response capability from 80 Hz to 20 kHz. Especially in the mid-frequency band, the performance is excellent, and the vocal restoration is full, mellow and full of emotion, which is praised by many listeners as “vocal poison”.
2. Precision directivity control:The unique horn-type bullet metal mesh design can accurately guide the sound energy to the listening area, and its sound field positioning accuracy can theoretically reach 0.1 degrees, ensuring the stability and accuracy of sound imaging.
3. Tip diaphragm and cavity material:The diaphragm is made of ultra-lightweight magnesium alloy material, combined with Bi Wei’s patented MAGNEOLA alloy casting shell. This combination achieves lightweight while ensuring extremely high rigidity, which increases the transient response speed of the unit by 50%, and the sound response is quick and clean.

4. Full-scenario system adaptability:This unit is designed with a high degree of flexibility in mind. It can either take on core tasks as the main speaker of the front soundstage, or it can be specifically used to enhance the center vocal, and it can also be used as a surround channel to supplement the soundstage. A set of products provides car owners with a variety of system construction and gameplay.
5. Exclusive acoustic cabinet black technology:Biwei has developed a precisely calculated dedicated mounting cavity (cup cover) for it. This small “box” can effectively suppress harmful standing waves and resonances in the cavity. After actual tests, it can significantly improve the purity of timbre by about 30%, making the details clearer and the background darker.

█ Recommended three mainstream upgrade solutions
Based on your existing system and listening needs, we recommend the following three efficient upgrade paths:
Plan ① Special upgrade of center channel:Directly replacing the center speaker of the original car is the most direct and efficient way to improve the clarity of vocal dialogue and enhance the image in the center of the sound field.
Scheme ② Surround sound field enhancement construction:Install this unit in the rear sound field or rear surround position, and cooperate with the front main sound field to easily create an enveloping “panoramic sound” immersive experience.
Scheme ③ Treble replacement and intermediate frequency completion of two-way system:For car owners whose two-way system has been modified or the original car feels that the voice is shriveled and the mid-frequency is sunken, directly replacing the original tweeter with it can solve the dual problems of high-frequency extension and mid-frequency fullness in one fell swoop.

█ Tips for professional installation and commissioning
This product supports non-destructive installation of original parking spaces for most models. In order to give full play to its potential in different scenarios, we strongly recommend fine adjustment with a professional DSP audio processor:
• When used in center mode:In DSP, the core vocal frequency band of 800 Hz-3 kHz can be properly focused and enhanced to make the vocal more prominent and clear.
• When surround mode is used:The tuning idea of broadband diffusion should be opened, and the delay should be appropriately increased, so that the sound can be better integrated into and set off the overall sound field, instead of pointing to a certain seat abruptly.
• When used instead of treble mode:It is necessary to accurately set the crossover point and slope between it and the woofer unit in the door panel to ensure a smooth frequency transition between the two units and a seamless integration.
