Jantzen Audio 000-0157 | 1,75 mH | 0,69 Ω | 3% | 18 AWG

The Jantzen Audio 000-0157 air core coil is a precision component designed for audiophile-grade loudspeaker crossover networks. With an inductance of 1.75 mH and a DC resistance of just 0.69 Ω, this inductor ensures minimal signal loss and accurate frequency filtering, making it an ideal choice for demanding audio enthusiasts and professional speaker builders alike.

This air core coil excels in high-fidelity crossover designs where low distortion and linear performance are paramount. It is particularly well-suited for use in two-way or three-way speaker systems, as well as in custom DIY audio projects where component quality directly impacts sound clarity. The ±3% tolerance guarantees consistent performance across production batches, allowing for reliable and repeatable results in both prototyping and manufacturing.

Constructed with 18 AWG wire and a 1.02 mm diameter conductor, the coil features an air core design that eliminates core saturation and hysteresis effects, preserving signal integrity even at higher power levels. The physical dimensions of 59 x 15 mm make it compact enough for integration into tight enclosures, while the 3% power tolerance (RMS) ensures stable operation under typical audio loads. Each unit is wound with precision to maintain exact inductance values, supporting accurate crossover slopes and phase alignment.

For your next speaker build or crossover upgrade, this Jantzen Audio inductor delivers the technical consistency and sonic transparency required to achieve a refined, natural soundstage. Its robust construction and tight tolerances make it a dependable choice for both hobbyists and seasoned designers.
