High-end tweeter-range magnetostat. Solid aluminium die-cast front. Effective from 4000 Hz upwards due to the large diaphragm area and low self-resonance. The extremely thin base layer of the diaphragm means there is very little mass to set in motion which guarantees a high degree of signal fidelity and broad frequency response. High efficiency is guaranteed by the neodymium boron magnets. Low distortion factor, good power-handling capabilities, highly linear impedance and amplitude frequency response and the broad frequency response range make the MHT 12 - 8 Ohm a highly versatile tweeter unit for the discerning listener. Screened magnets.
