Model

Part Number UM Features
3" Ribbon Tweeter JP3.0 each Features:
• High-pressure injection molded 5mm faceplate.
• Pure Aluminum ribbon.
• Super strong Neodymium magnet
• Frequency range from 1700Hz to over 40kHz
• Extremely thin foil (0.009mm) for a high degree of signal fidelity and broad frequency response.
• Low distortion and high power handling
• Flat impedance response

Ribbon Material: Aluminum
Ribbon Mass: 11 mg
Ribbon dimension: 8mm x 60mm x 0.009mm
Impedance: 6 ohm
Frequency Response: 1,700Hz ~ 40,000Hz
Sensitivity: 95dB/W/m
Power Handling: 14W nominal 40W max
Suggested x-over frequency: 2500Hz
Weight: 560g / 1.28lb

 

Electronic crossovers show a dead short to the amp, you must use a passive component too!

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 powering off amplifier is a must before connection.

Full Range Test is not recommended, because in the low frequency the impedance of tweeter is almost zero, which makes it very easy to burn the tweeter and overload the amplifier. Never do any test below 200Hz.

200 millivolt may be used to test frequency.
