Jantzen Audio 000-2045 | 2,5 mH | 0,44 Ω | 3% | 18 AWG

The Jantzen Audio 000-2045 iron core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. As a 2.5 mH inductor with a low DC resistance of just 0.44 Ω, it ensures minimal signal loss and efficient power handling, making it an ideal choice for audiophiles and DIY speaker builders who demand precise crossover network behaviour.

This coil excels in passive crossover designs, where it effectively filters and directs specific frequency ranges to the appropriate drivers—be it woofers, midrange units, or tweeters. Its stable inductance is particularly beneficial for two-way and three-way speaker configurations, ensuring consistent sound reproduction across the audio spectrum. Whether you are upgrading an existing pair of speakers or constructing a custom set from scratch, this component delivers reliable, predictable results.

Technically, the inductor features a ±3% tolerance, guaranteeing accurate inductance values for repeatable crossover points. The 1.02 mm diameter wire (18 AWG) is wound on a robust iron core, which provides high saturation levels and compact dimensions of 34 x 35 mm. This design allows for easy integration into tight enclosures while maintaining excellent thermal stability. The iron core construction also minimises external magnetic interference, preserving signal integrity.

In summary, the Jantzen Audio 2.5 mH iron core coil combines precision engineering with practical usability, offering a dependable solution for achieving refined, natural sound in any high-quality audio project.
