        Product description

        Bliesma M74B-6 features large beryllium dome for low non-lineal distortions. Moving mass of the driver is as low as 1.8 g.



        • 74 mm beryllium dome for wide bandwidth and low non linear distortion
        • 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

        Ik ontwikkel high end luidsprekers en ik heb voor het eerst een Bliesma M74-B voor het midden in combinatie met een Bliesma T25-B tweeter toegepast. Het resultaat is werkelijk fascinerend,. Je luistert er dwars doorheen, een ongekende resolutie,dynamiek en ongekleudheid. Er valt ook nagenoeg niets te corrigeren met zulke vlakke impedantie curves. Technisch zeer hoogwaardige drivers.
