The Fountek NeoCD2.0 is a true ribbon tweeter featuring an 8 x 120mm diaphragm, a high power neodymium magnet and a rectangular alloy faceplate. The ribbon material is an ultra light (10mg) multilayer aluminium sandwich with a cross section of 0.015mm (approx 0.6 thou).
This larger ribbon tweeter has a high sensitivity of 97 dB and a broad operating range of between 1.2 kHz to well above audibility. 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 2.5kHz / 18db octave.
