Test Bench: The New LM10n Wide Band Midrange Ribbon Transducer from Radian Audio Engineering

This is the eagerly awaited characterization of the new LM10n planar ribbon from Radian Audio, one of the most interesting drivers launched in 2023. Like all of Radian's latest planar transducers this one was designed by 35-year loudspeaker engineering veteran Igor Levitsky, with the LM10n being the latest and larger sized model, described as a wide range 120Hz to 20kHz ribbon planar transducer, which excels as a midrange and can be utilized in both open-back (dipole) and closed-back (monopole) formats.

In its August 2020 edition, Voice Coil featured an article by experienced speaker designer Igor Levitsky, highly recognized in the industry for developing some of the best planar magnetic speaker and headphone drivers for some of the most reputed brands, focusing precisely on this type of technology. It seems clear that we will see more and more headphones and speakers using thin-film drivers, as the industry is now perfecting the use of different types of diaphragms and materials. The August 2020 edition of Voice Coil includes the first part of this article, completed in the September 2020 edition.
