Jantzen Audio 000-1757 | 0,33 mH | 0,293 Ω | 3% | 18 AWG

The Jantzen Audio 000-1757 air core coil is a precision component designed for audiophiles and speaker builders who demand uncompromising sound quality. This 0.33 mH inductor ensures accurate crossover filtering, allowing you to achieve clean signal separation between drivers for a natural, detailed soundstage. Whether you are constructing high-end loudspeakers, upgrading existing crossovers, or repairing vintage audio equipment, this coil delivers reliable performance that enhances your listening experience.

Technically, the coil features a DC resistance of just 0.293 Ω, minimising power loss and preserving amplifier efficiency. The 18 AWG wire diameter (1.02 mm) strikes an excellent balance between low resistance and manageable physical size, while the ±3% tolerance guarantees consistent behaviour across production batches. Measuring 29 x 27 mm, this air core design eliminates core saturation and hysteresis distortion, ensuring linear performance even at higher signal levels. The self-supporting winding maintains structural integrity without the need for a ferromagnetic core, making it ideal for critical audio applications where purity of signal is paramount.

Finished with Jantzen Audio’s renowned build quality, this coil is a trustworthy choice for any serious crossover project. Its precise specifications and robust construction will help you realise the full potential of your speaker system.
