铜箔线圈 COPPER FOIL COILS
The reproduction of music by coils made of solid metal foil (also referred to as ribbon coils) excels by extraordinary dynamics, unparalleled detail and holographic spatial quality and lowest distortions and discolorations - Even finest nuances are represented in a realistic manner.
Another remarkable feature is the high mechanical stability of these types. Due to the large contact surface between the individual windings and the viscoplasticity isolation of the polyprobylene foil the oscillations of the individual windings are eliminated effectively. Foil coils have the lowest measured vibrations.
When using foil instead of wire for inductors, the enlarged surface will make for a much higher rate of electron travel.
The benefits from using foil inductors comes in the form of less distortion and higher dynamic headroom, when used on crossovers for modern high performance speakers.
