The Cross Coil has been developed in cooperation with Audio Technology, Denmark, producing high-end drivers for the world market.
No chain is stronger than its weakest link. This is especially so when we speak of loudspeakers, where there is often a cost reduction for crossover inductors. The result is distortion and power loss. High-end loudspeaker producers overcome this problem by using foil coils, where the copper is flat instead of round.
If you take a 1.6 mm² copperwire and roll it flat, the copper surface area becomes 12 times larger. And why is this an advantage?
We know that with rising frequency, the electrons will reach for the surface. This Phenomenon is known as power distortion. And this is why we need as large a surface as we can get, so the electrons do not "get squeezed" along the way. Until recently, the only disadvantage with foil inductors was the price. But with Jantzen Audio’s new production methods and specially constructed machinery, the price has been greatly reduced.
