JP3.0 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 1,400Hz upwards due to the large diaphragm area and low self-resonance.
Extremely thin diaphragm (0.009mm Aluminum foil) 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
