Jantzen Audio 000-1309 | 1,7 mH | 1,20 Ω | 3% | 21 AWG

The Jantzen Audio 000-1309 air core coil is a high-quality component designed for audiophiles and speaker builders who demand precision in their crossover networks. This 1.7 mH inductor delivers consistent performance, making it an excellent choice for both DIY projects and professional loudspeaker designs. Its air core construction eliminates core saturation and distortion, ensuring pure signal transmission for critical audio applications.

This coil is ideally suited for use in two-way or three-way speaker crossover circuits, where it effectively filters midrange or high-frequency drivers. It also works well in passive subwoofer crossovers, providing clean bass management without introducing unwanted harmonics. Hobbyists upgrading existing speakers or engineers prototyping new designs will appreciate its reliable specifications.

Technically, the coil features a 1.7 mH inductance with a tight ±3% tolerance, ensuring accurate crossover points. The 21 AWG wire (0.72 mm diameter) offers a low DC resistance of 1.20 Ω, minimising power loss and heat buildup. Its compact dimensions of 38 x 15 mm allow easy mounting on circuit boards or inside enclosures. As a true air core design, it avoids the nonlinearities of ferrite or iron cores, preserving audio clarity.

For your next loudspeaker project, this Jantzen Audio coil provides the precision and sonic transparency needed for high-fidelity results. Its robust build and tight tolerances make it a reliable choice for discerning audio enthusiasts.
