Jantzen Audio 000-1704 | 3,7 mH | 3,25 Ω | 3% | 24 AWG

The Jantzen Audio 000-1704 air core coil is a high-quality component designed for audiophile-grade loudspeaker crossover networks. Its precision construction ensures minimal signal loss and exceptional clarity, making it an ideal choice for discerning audio enthusiasts and professional speaker builders alike. This 3.7 mH inductor is particularly suited for low-pass filtering in two-way or three-way speaker systems, where accurate bass and midrange reproduction is critical. It also excels in impedance correction circuits, helping to maintain a stable load for amplifiers and improve overall system coherence.

Technically, this coil features a 24 AWG copper wire winding on a non-magnetic former, which eliminates core saturation and hysteresis distortion—common issues in iron-core alternatives. With a DC resistance of just 3.25 Ω and a tight ±3% tolerance, it offers consistent performance and efficient power handling. The compact dimensions of 33 x 15 mm allow for easy integration into crowded crossover boards, while the air core design ensures linear inductance across a wide frequency range. Whether upgrading an existing design or building from scratch, this Jantzen Audio coil delivers reliable, low-distortion filtering that enhances the listening experience.
