Jantzen Audio 000-1151 | 1,45 mH | 0,87 Ω | 3% | 20 AWG

The Jantzen Audio 000-1151 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Its 1.45 mH inductance and low 0.87 Ω DC resistance ensure accurate frequency filtering with minimal signal degradation, preserving the clarity and detail of your audio.

This coil is ideal for DIY speaker builders and repair technicians seeking to upgrade or restore crossover circuits in high-fidelity systems. It suits both two-way and three-way designs, particularly where a midrange or woofer filter requires a reliable, non-saturating inductor. The air core construction eliminates core losses and distortion, making it perfect for critical listening applications.

Technically, the coil uses 20 AWG wire with a 0.81 mm diameter, wound on a 42 x 15 mm former. The ±3% tolerance guarantees consistent performance across production batches, while the air core design ensures linear behaviour across the audio band. Its compact dimensions allow easy integration into crowded crossover boards.

For your next speaker project, this Jantzen Audio coil delivers the transparency and accuracy expected from a premium passive component. Whether you are fine-tuning a vintage pair or building from scratch, it provides a dependable foundation for your crossover network.
