Product Features
Jantzen's iron cores and discs are made from non-ferrite pressed Somaloy iron powder.
Jantzen generally recommends application of Iron Core Coils for bass & midrange sections on crossovers and as a rule of thumb; for positions on the crossover crossed below 1.2 kHz.
All ferromagnetic cored inductors will have various levels of audible noise distortion (hum).
When such noise / distortion (hum) becomes audible will depend on various driver and crossover specific factors, which is best determined by doing real world listening tests.
For more information about non-ferrite and ferrite cored inductors, please read our article found here.
The Iron Core Coils with Discs feature low DCR which does not alter driver damping factor or add to loss of efficiency.
Power handling capability is determined by core size and wire thickness.
It features high-purity copper wire and is made with baked wire (bonding lacquer) spliced onto an iron (non-ferrite) core.
The iron core coil with end disc features less copper wire and due to more core/disc material thereby also higher distortion but have a lower cost due to less copper usage.
