Hi everyone, Lately I've been researching on electrical damping factor, and especially the effects a high impedance output could have on planar magnetic drivers. It has been well known for a long time that electrical damping can have an influence on the frequency response of drivers, as clearly exposed in the article reproduced here, which dates back to 1954 : http://www.paulspeltz.com/tomcik/index.html Obviously this is a concept that a lot of people understands here, most likely much better than me. It is also quite well known that low damping factor is affecting the bass frequency response in regular drivers. However I have some difficulties to find some conclusive information on low damping factor with planar magnetics, given their essentially flat impedance curve. Does anyone know about studies done on the subject ?
