he Fountek NeoPro10i is a 4th generation high power, high efficiency (102dB) large format true ribbon tweeter featuring a 255mm / 10 inch ribbon and a very powerful neodymium magnet system. The NeoPro10i has a very broad, low distortion frequency response of between 700 Hz - 40 Khz. The ribbon material is an ultra light (14mg) multilayer aluminium sandwich with a cross section of 0.015mm (approx 0.6 thou).
The end tensioning clamps form a substantial heatsink for the low impedance ribbon and an impedance matching transformer is built into the back of the housing.
We recommend a minimum crossover frequency of 1kHz / 18db octave.
