Fountek NeoCd2.0 Ribbon Tweeter

Fountek Electronics Co.

NeoCD2.0 5" Ribbon Tweeter

NeoCD2.0 ribbon tweeter is a high-performance component which is probably the best choice to building/upgrade your loudspeaker.

Feature

Super strong Neodymium magnet fro high efficiency
Build-in impedance conversion transformer
Effective from 1,200Hz upwards due to the large diaphragm area and low self-resonance.
Thin enforced sandwich ribbon diaphragm guarantees a high degree of signal fidelity and broad frequency response.
Low distortion factor, good power-handling capabilities, high linear impedance and amplitude frequency response and the broad frequency response range.
Flat impedance from 1,000 to 40,000Hz

Ribbon tweeters show a dead short to your amplifier! You must use a capacitor on them, when testing them or when using them with an electronic crossover!

Fountek Ribbon Testing Instructions

0.5W@0.5meter signal from 1,000Hz~40,000Hz - without capacitor, and must make sure amplifier is well connected with tweeter
Turn off the amplifier before suspending the connection, and power off amplifier is a must before connection.
We do not suggest Full Range Test, because in the low frequency the impedance of tweeter is almost zero - which is very easy to burn the tweeter and makes the amplifier overloaded
Users may use 200 millivolt to test frequency, never do any test below 200Hz
