Jantzen Iron Core Coils

Jantzen iron core coils/inductors are made from non-ferrite pressed Somaloy iron powder. These are generally recommended for the bass & midrange sections on crossovers. They offer a higher inductance in a smaller package than an air-core coil/inductor. They are therefore useful for applications where space is limited and cost is a premium.

The Iron Core Coils feature low DCR, which does not alter the driver's damping factor or contribute 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 coils without end-disc features more copper wire and, due to the less core/disc material, have lower distortion, which may be a better choice if the distortion from an equivalent value Iron Core Coil with discs is audible. Low inductance tolerance of +/-3%.

On comparing the two types of Iron Core coils, most customers prefer the coil without discs, especially if space on the crossover is not an issue. Sonically, there is no significant difference between the two types.
