This Fountek ribbon is a well-known winner in the Price vs. Performance Sweepstakes. US New Retail price is about $125 each. The Fountek NeoCD3.0 is a true ribbon tweeter featuring an 8 x 60mm diaphragm, a high power neodymium magnet and a 110mm circular alloy faceplate. The ribbon material is an ultra light (10mg) multilayer aluminum sandwich with a cross section of 0.015mm (approx 0.6 thou). This medium sized ribbon tweeter has a high sensitivity of 93 dB and a broad operating range of between 1.4 kHz to 40 Khz. 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. Representing an excellent price / performance / size ratio, this tweeter has been used in various high end designs. Fountek recommends a minimum crossover frequency of 2.5kHz @ 18db/octave.

Fountek NeoCD3.0 3 Ribbon Tweeter [ $250.00 per pair retail price ]Super strong Neodymium magnetsBuild-in impedance conversion transformerEffective from 1,400Hz 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 Warning:Ribbon tweeters should always be used with a passive crossover! They are a dead short to the amplifier.Do not test without a capacitor. Do not use an electronic crossover without a capacitor (we use 20+ mfd).Tweeters are repairable at Madisound for a very reasonable price. Call us to make arrangements.
