Studies of loudspeaker components most often concentrate on the functions that add or detract from the acoustically measurable performance aspects of loudspeakers - such as cones, suspensions, or magnet and motor assemblies. On the other hand, application of litz wire into the loudspeaker design is not well documented. Yet the litz wire has a profound impact on reliability and has a propensity to cause problems such as unacceptable extraneous noise. After a review of classical theory on the vibration of strings, bars and elasticity one will surmise that understanding the vibration of litz wire is not trivial. This paper reviews a loudspeaker case study and the ramifications of using behaved and not so well behaved litz wire.
