Jantzen Audio 000-1687 | 13 mH | 4,97 Ω | 3% | 21 AWG

The Jantzen Audio 000-1687 air core coil delivers the precision and transparency demanded by discerning loudspeaker designers. As a 13 mH inductor with a DC resistance of just 4.97 Ω and a tight ±3% tolerance, this component is engineered for accurate crossover filtering that preserves the integrity of your audio signal. Its air core construction eliminates the core saturation and hysteresis distortion found in iron-core alternatives, making it an ideal choice for high-fidelity two-way and three-way speaker systems where clarity and detail are paramount.

This coil excels in passive crossover networks for bookshelf speakers, floor-standing towers, and studio monitors, particularly in low-pass and band-pass sections where stable inductance is critical. The 21 AWG wire gauge strikes an excellent balance between low resistance and manageable physical size, while the 50 x 60 mm dimensions allow for straightforward integration into most crossover boards. The ±3% tolerance ensures consistent performance across production runs, a vital feature for matched pairs or multi-way designs.

Technical highlights include the air core format, which guarantees linear behaviour across the entire frequency range, and the precision-wound coil that minimises parasitic capacitance. Whether you are upgrading an existing design or building from scratch, this Jantzen Audio coil provides the reliability and sonic transparency that define high-end audio engineering.
