— Radian Audio Engineering Planar Ribbon family is expanded with new wide band LM10n driver, and next-generation drivers with improved specifications for home audio, home cinema and high end applications. —
Pomona, CA, January 3, 2023 — Following an intense research and development effort, Radian Audio Engineering is proud to present its extended Planar Ribbon range for the first time at CES 2023. Expanding the much improved new-generation Planar Ribbon series, Radian now introduces the largest driver in the family, the wide band LM10n.
Speakers based on drivers with thin-film diaphragms deliver exceptional sound quality in mid- and high-frequency ranges. Radian Planar Ribbon drivers embody the latest advancements in R&D and production know-how based on nearly four decades of experience in the development of this technology for a wide range of applications.
At the heart of Radian’s planar ribbon technology lays a symmetric push-pull, FEA-optimized magnetic structure based on very high MGO energy neodymium magnets with very even magnetic flux distribution. A lot of care has been applied to the metal parts design to minimize stray flux, maximize efficiency, and reduce and even eliminate distortion related to the magnetic structure.
Special focus has been given to the mechanical design to ensure dimensional stability, longevity, and toughness of the drivers for the most demanding applications.
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.
LM10 Unique Attributes:
- 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 Applications
All the new Radian ribbon devices were designed by 35-year loudspeaker engineering veteran Igor Levitsky. Levitsky began designing planar ribbon drivers and speakers in 1986 as a young engineer after graduating in electroacoustics from Kiev Technical University. Beginning in 1995, Levitsky worked with Hi-Vi Research, where he developed a complete production process for manufacturing ribbon diaphragms. Over the next 20 years, Levitsky developed planar ribbon drivers and speaker systems for the consumer market, working for BG Radia (acquired by Christie Digital in 2014) and for the pro market with SLS Audio (acquired by Dolby in 2014). Levitsky also worked with OPPO Digital and Dai-ichi Electronics Manufacturing Corp. on the development of the award-winning OPPO PM1 and PM3 planar magnetic headphones. He joined Radian in 2017 with the goal of bringing the latest planar ribbon technology innovations to the pro sound and residential markets. Levitsky holds a total of six patents on planar ribbon drivers and speaker design.
"The LM10 has exceptional, if not technically ideal, electro-magnetic properties for a transducer. Most conventional drivers struggle with distortion mechanisms related to magnetic structures, modulation of magnetic flux by signal current, eddy currents, hysteresis and other factors generating most subjectively offensive distortions," says loudspeaker engineering veteran Igor Levitsky.
"The LM10n magnetic circuit does not have metal that plays any significant role in magnetic flux conduction. Naturally, the LM10 is devoid of parasitic effects that generate those distortions. Another unique feature is that LM10’s current carrying conductors are not formed in a cylindric coil but represent a flat pattern with almost zero inductance. Inductance is a well-known parasitic factor directly linked to different distortions among which intermodulation is most prevailing and sonically disturbing," he details.
LM10n Applications
Optimal application as a midrange paired with Radian’s LT3 or LT2 tweeters.
Open back/dipole configurations would result 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 LM10 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.
Radian Audio is showcasing the new LM10n and other new drivers at the ALTI Association Hospitality Suite at CES 2023, Lido 3101B - Level 3 of the Venetian Expo and Convention Center.
