The Jantzen Audio 000-1189 air core coil is a premium component designed for audiophiles and loudspeaker builders who demand uncompromising sound quality. This 0.42 mH inductor ensures precise crossover filtering, allowing your speaker designs to deliver a clean, natural frequency response with minimal signal degradation. Its air core construction eliminates core saturation and hysteresis distortion, making it ideal for high-fidelity audio systems where clarity and detail are paramount.

This coil is perfectly suited for use in passive crossover networks for bookshelf speakers, floor-standing towers, and studio monitors. It excels in both two-way and three-way designs, providing accurate bass management and seamless driver integration. The tight ±3% tolerance guarantees consistent performance across production runs, essential for matched pairs or multi-speaker setups.

Technical features include a 15 AWG wire diameter of 1.45 mm, which offers low DC resistance of just 0.19 Ω, minimising power loss and heat buildup. The coil measures 46 x 30 mm, making it compact enough for tight enclosures while maintaining excellent current handling. As a true air core design, it avoids the nonlinearities of ferrite or iron cores, preserving the purity of your audio signal.

Whether you are upgrading an existing design or building from scratch, this Jantzen Audio coil delivers reliable, high-performance filtering for your most demanding projects.
