Jantzen Audio 000-1843 | 0,47 mH | 0,48 Ω | 3% | 20 AWG

The Jantzen Audio 000-1843 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 0.47 mH and a DC resistance of just 0.48 Ω, this coil ensures accurate signal filtering while minimising energy loss, preserving the clarity and detail of your audio system. Ideal for use in high-fidelity speaker builds, it excels in crossover designs where precise frequency separation is critical—whether you are constructing bookshelf speakers, floor-standing towers, or custom studio monitors. The air core construction eliminates core saturation and distortion, making it a preferred choice for purists seeking transparent sound reproduction. Technically, the coil is wound with 20 AWG wire (0.81 mm diameter) and offers a tight tolerance of ±3%, ensuring consistent performance across production batches. Its compact dimensions of 33 x 15 mm allow for easy integration into tight enclosures. The air core design also avoids the hysteresis and eddy current losses associated with ferrite or iron cores, delivering linear behaviour across the audio band. Whether you are upgrading an existing crossover or building from scratch, this Jantzen Audio coil provides the reliability and sonic accuracy demanded by discerning listeners and DIY enthusiasts alike.
