[Audio modification ceiling] In-depth evaluation of Biwei A series two-way frequency: mica diaphragm + zero-loss transmission, how to become the “king of human voice”?

▶ Biwei A-series two-way speaker: Why is it called the “reference speaker in the modification industry”?

 

In the field of high-end car audio, Biwei ( BEWITH) Has always been synonymous with “German precision acoustics”, and A series two-way frequency It’s a classic. It doesn’t rely on exaggerated “boom bass” to win, but with Ultimate restoration, zero-loss transmission, seamless frequency response connection Conquer professional players.

Three core technical highlights

 

1. Unidirectional sound transmission and zero sound loss

 

 

Traditional horn: The sound spreads and hits the door interior, causing reflection distortion.

 

 

Biwei Series A : adopt Precision waveguide technology , the sound waves are transmitted directionally like laser beams and reach the human ear directly, Detail loss is almost zero , especially suitable for vocals and classical music.

2. Ultra-wide frequency response range · The connection is as smooth as silk

 

 

The tweeter can dive to 2.5 kHz , the midwoofer unit reaches up to 5 kHz , the overlapping frequency band far exceeds the ordinary two-way frequency.

 

 

Actual hearing sense : There is no fault in the transition from violin to baritone, and big dynamic music can also be maintained The smooth feeling of “one line”.

3. Mica diaphragm is clean enough to “count the breathing sound”

 

 

The material of the diaphragm determines the timbre soul! Biwei Selection Multilayer mica composite diaphragm , high rigidity and strong internal resistance, Fast transient response , the vocal tooth sound and the graininess of guitar strings are clearly recognizable.

 

 

Compared to ordinary PP basin Low distortion rate of mica diaphragm 30% , especially suitable for monitoring enthusiasts.

 

 

▶ Door panel box modification: “heart surgery” in the audio industry

 

No matter how top-level the speaker is, if the installation environment is unprofessional, the sound quality will be directly 50% OFF! The strength of Biwei A Series is brought into play, Reliance on high-specification door panel box modification -This is also the core competitiveness of music broadband.

 

 

Why is the door box “Ceiling-level” modification?

 

1、 Acoustic cavity customization

 

 

Original Door Panel Yes “A broken speaker that leaks “, we passed 3 D scanning + resin infusion , create a sealed box to improve the solidity of medium and low frequencies 50% 。

2、 Balance of shock absorption and rigidity

 

 

Internal reinforcement Aerospace aluminum , external coverage High density sound insulation material , while eliminating resonance, let the mica diaphragm “Let go and work”.

3、 Professional equipment blessing

 

 

Using Laser locator Calibrate the horn angle, Sound pressure tester Verify the frequency response curve to ensure that the modified parameters are close to the laboratory data 。

 

 

▶ Who is suitable for choosing Biwei A Series?

 

1. Pursuit Enthusiasts of “true restoration” (Hate music dyeing, love listening to jazz, classical music, Live recording)

 

2. Players willing to invest in in-depth modification of door panels (Box process accounts for the entire budget 30% , but the effect is immediate)

 

3. Hate Car owners with “muffled sound after modification” (orientation Transmission technology specializes in door reflection distortion)
