LM10N - Wide Band Planar Ribbon Transducer

The Radian LM10n is a wide band planar ribbon driver with a recommended operating frequency band 150Hz-20kHz. Its flat pattern of straight conductors is evenly distributed over a stretched polymer diaphragm and disposed in a symmetric magnetic structure. As a result, the inductive component of input impedance is eliminated and hence intermodulation distortion is minimized. LM10n Unique Atributes: - Exceptional midrange band reproduction - Superior sonic transparency and resolution - Textbook constant directivity in horizontal plane - High energy Neodymium magnets - Advanced polymer diaphragm with extremely linear operation over wide dynamic range - Symmetric push-pull balanced system - Resistive impedance with negligible inductive component - Structurally inert design optimized for long-term operational stability - Thermally conductive polymer frames - Optimized for line array application LM10n Applications: Optimal application as a midrange paired with Radian LT3 or LT2 tweeters. Open back/dipole configurations results in very airy, spacious, three-dimensional presentation. Closed back alignment results in a more direct, immediate and focused sonic images. The LM10n is a great choice for line arrays having a maximized ratio of active radiating area to overall driver height (an array of LT3s or LT2s is recommended for ultimate performance), including coplanar/coaxially located arrays. The Radian LM10n can be used for open back near field monitors, augmented with a subwoofer, delivering a holographic sonic reality for the ultimate in desktop high performance.
