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.

Audio Myths: Why Narrow Bandwidth May Be Better also in the Time Domain.

Audio Myths: Why Narrow Bandwidth May Be Better also in the Time Domain.

This article expands the conversation around feedback theory for electronic circuits and audio amplifiers. Do we "really" need wideband open loop in audio amplifiers? The subject came up at the 154th Audio Engineering Society (AES) convention in Helsinki, Finland. Looking at the frequency domain, not necessarily, Jan Didden argued. In this article he looks at the question in the Time Domain. Narrow Bandwidth, High Open Loop Gain Amplifier versus a Wide Bandwidth, Low Open Loop Gain Amplifier in the Time Domain.

Audio Myths: Why Narrow Bandwidth May Be Better

Audio Myths: Why Narrow Bandwidth May Be Better

Although feedback theory for electronic circuits has been established for over a century, it is still a subject for discussion. This short essay is an attempt to shed some light on one of those recurring controversies. The subject came up at the 154th Audio Engineering Society (AES) convention in Helsinki, Finland. Audio amplifiers are basically integrators or, if you will, low-pass filters. That means that at some frequency, their open-loop gain starts to fall off. With that, the loop gain available for feedback also starts to fall off, leading to a diminishing of the curative effects of feedback: distortion starts to rise, gain accuracy starts to drop, output impedance starts to go up, etcetera.
