        Product description

        Bliesma M74S-6 midranges have extremely low mass (2.0 g) of moving part, with linear excursion of 2.4 mm. Single-layer ribbon CCAW (Copper-clad Aluminum Wire) voice coil of Bliesma M74S-6 is wound on titanium former.



        • 74 mm AlMg alloy dome with variable thickness
        • Extremely low moving mass for better transient response and higher efficiency
        • Fully saturated neodymium motor with copper sleeve for low non linear and modulation distortion
        • 2.4 mm linear excursion (P-P) and large vent channel for undistorted low frequency operation
        • Thick aluminium powder coated flange
        • Aluminium rear chamber with natural wool damping
        • Recommended frequency range Fs - 6 kHz

        This driver is in the absolute top range of midrange drivers. Very high sensitivity, high SPL and smooth frequency range. Easy to integrate, very low THD. Why only 4 stars? I directly compared to the Aluminium version and the silk driver is more "gentle" and softens the sound a little. It brings a sound by itself which means it's not as honest as the metal driver. (e.g. Crash cymbals sound less "explosive" and metal as they are) This can be t...
