The rectangular version of the exceptional NeoCD3. Flange is 115mm tall x 75mm wide.
Super strong Neodymium magnetsBuild-in impedance conversion transformer Effective 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
