110mm ROUND CLASSIC AUDIOPHILE TRUE RIBBON
SOLD IN MATCHED PAIRS
Extremely thin Pure Aluminium 0.009mm Ribbon Diaphragm. Super strong Neodymium magnet for high efficiency. Built-in Linear Impedance conversion transformer. Incredibly flat impedance for easy crossover design. Effective from 1,700 Hz upwards due to the large diaphragm area and low self-resonance. High degree of signal fidelity and broad frequency response. Only 11mg mass for instantaneous signal response and micro-detail. Low distortion factor, good power-handling capabilities, highly linear impedance and amplitude frequency response and broad frequency response range. Flat impedance curve from 1KHz to 40KHz. This deluxe speaker range is individually factory tested and assessed then they are paired for specific efficiency and response matching. Ridged High-pressure injection moulded 5mm thick faceplate. Very competitively priced for this level of refined technology. Upgrade to the ultra high frequency response of today's audio equipment! Recommended crossover frequency 2,500Hz with -18dB Filter. The higher the crossover point, the higher the power rating of the ribbon.
