Crossover networks, when improperly designed and/or laid out (component-wise) are a proven, significant contributor to a system's noise picture. In the case of inductor coils there exist a handful of ways they can generate unwanted noise. First among these being mutual coupling or “crosstalk" as perhaps it is better known.<SPAN style="mso-spacerun: yes">&nbsp; </SPAN>This article explores the phenomenon and also gives guidance on how to orient inductors in a loudspeakers crossover to yield optimal results.<SPAN style="mso-spacerun: yes">&nbsp; </SPAN></SPAN></P>
