Jantzen Audio 000-1146 | 0,15 mH | 0,29 Ω | 3% | 21 AWG

The Jantzen Audio 000-1146 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 0.15 mH and a DC resistance of just 0.29 Ω, this coil ensures minimal signal loss and accurate filtering for high-fidelity sound reproduction. Its ±3% tolerance guarantees consistent performance, making it an excellent choice for both DIY enthusiasts and professional speaker builders who demand reliable crossover behaviour.

This air core coil is ideally suited for use in high-pass and band-pass filter sections where low distortion and linearity are paramount. It excels in two-way and three-way speaker systems, particularly in tweeter and midrange circuits where preserving transient response and detail is critical. The non-saturating nature of the air core design eliminates core losses, ensuring pure signal transmission even at higher frequencies.

Constructed with 21 AWG wire and a wire diameter of 0.72 mm, the coil offers a robust yet compact form factor measuring 25 mm by 8 mm. The air core construction avoids the hysteresis and eddy current losses associated with ferromagnetic cores, delivering cleaner sound with improved imaging. Each coil is wound with precision to maintain tight tolerance and consistent inductance across production batches.

For your next speaker project, this Jantzen Audio air core coil provides the technical foundation for a transparent and accurate crossover. Its combination of low resistance, tight tolerance, and air core purity makes it a dependable choice for achieving high-end audio performance.
