Jantzen Audio 000-1128 | 0,85 mH | 0,64 Ω | 3% | 20 AWG

The Jantzen Audio 000-1128 air core coil is a meticulously engineered component designed to elevate the performance of high-fidelity loudspeaker systems. As a fundamental element in crossover networks, this 0.85 mH inductor ensures precise signal separation, allowing each driver to operate within its optimal frequency range for a clean, natural sound reproduction. Its air core construction eliminates the risk of core saturation, making it an excellent choice for audiophiles and DIY enthusiasts seeking transparent, distortion-free audio.

This coil is ideally suited for use in passive crossover designs for bookshelf speakers, floor-standing towers, and studio monitors. Whether you are building a new set of speakers from scratch or upgrading an existing crossover, the 0.85 mH inductance value provides accurate filtering for midrange and tweeter circuits. The ±3% tolerance guarantees consistent performance across multiple units, which is critical for maintaining phase coherence and stereo imaging in matched pairs.

Technically, the coil features a 20 AWG wire diameter of 0.81 mm, resulting in a low DC resistance of just 0.64 Ω. This minimises power loss and heat generation, preserving the amplifier's damping factor. The compact dimensions of 37 x 15 mm allow for easy integration into tight enclosures. Each coil is wound with precision to ensure stable inductance over time, delivering reliable performance that meets the demands of serious audio projects.

With its robust build and precise electrical characteristics, this Jantzen Audio air core coil is a trustworthy choice for achieving high-quality crossover filtering in your next speaker design.
