IWISTAO Tweeter Driver Unit Beryllium Copper Film Neodymium Magnetic 20W 6 ohms 1.2K-40kHz Ultra Lightweight
Model No:WHFST-CBNE65
An alloy of beryllium and copper. It is a flexible material in copper alloys. It has high strength, elasticity, hardness, fatigue strength, small elastic hysteresis, corrosion resistance, wear resistance, cold resistance, high conductivity, non-magnetic, and no impact. Spark and a series of excellent physical, chemical and mechanical properties.
The beryllium copper film contains 16.7% beryllium and 83.3% copper, which can make the film very thin and not easier to break than pure beryllium film. After being processed into a diaphragm, the thickness of the entire diaphragm is only 0.015 mm (1.5 wires). The 0.04mm aluminum film and 0.03mm titanium film can't be surpassed. Therefore, the analytical power is extremely strong, that is, the delicate and durable hearing with silk film, and the splendor and broadness of brass instruments.
The ultra-high magnetic circuit is composed of neodymium magnet, and it is filled with a magnetic fluid. The magnetic fluid has three functions: assisting heat dissipation, providing damping of the horn diaphragm, reducing distortion and keeping the voice coil in the center position, and acting as a centering support To find the right positioning. The speaker can also use the copper diaphragm to dissipate the heat of the voice coil into the air to increase the speaker's power. Small size and high energy, as long as you are a enthusiast, you can't miss it.
