Jantzen Audio 8.2mH 15 AWG Iron Core Coil with Discs

Jantzen AudioPart # 255-122
Model: 000-5329

The Jantzen Audio Iron Core Coil with Discs are crossover inductors designed for the bass and midrange sections of loudspeaker systems. It uses bonded high-purity copper windings over a solid iron core, offering low DCR and tight tolerance control for stable, repeatable performance.

Key Features

  • Optimized for bass and midrange crossover applications
  • Low DCR design preserves amplifier damping and system efficiency
  • Wound with high-purity ETP C11000 copper wire with bonding lacquer
  • “With discs” design reduces copper use, lowering cost while increasing distortion slightly
  • Inductance tolerance ±3%
  • DCR tolerance ±3%

Overview

Jantzen Audio 8.2mH 15 AWG Iron Core Coil with Discs

Jantzen Iron Core Coil with discs

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.
