Jantzen Audio 000-1305 | 0,68 mH | 0,33 Ω | 3% | 17 AWG

The Jantzen Audio 000-1305 air core coil is a premium component designed for audiophiles and loudspeaker builders who demand uncompromising sound quality. This 0.68 mH inductor delivers precise crossover filtering, ensuring clean signal separation between drivers for a natural and transparent audio reproduction. Its air core construction eliminates core saturation and hysteresis distortion, making it an ideal choice for high-fidelity systems where every detail matters.

This coil excels in passive crossover networks for two-way and three-way speaker designs, particularly in tweeter and midrange circuits where low-loss performance is critical. It is also well-suited for custom audio projects, including vintage speaker restorations and DIY amplifier builds, where maintaining signal purity is paramount. The ±3% tolerance guarantees consistent performance across production runs, allowing for reliable and repeatable results in matched pairs or production batches.

Technically, the coil features a 17 AWG wire diameter (1.15 mm) for low DC resistance of just 0.33 Ω, minimising power loss and heat generation. The air core design, with dimensions of 46 x 30 mm, ensures stable inductance over a wide frequency range without the nonlinearities associated with ferromagnetic cores. This makes it an excellent choice for high-power applications and critical crossover points.

For discerning listeners and engineers alike, the Jantzen Audio 000-1305 air core coil offers a perfect balance of precision, reliability, and sonic transparency, elevating any loudspeaker design to reference-level performance.
