Jantzen Audio 000-1099 | 4,0 mH | 0,72 Ω | 3% | 15 AWG

The Jantzen Audio 000-1099 air core coil is a premium crossover component engineered for discerning audio enthusiasts and professional loudspeaker designers. This 4.0 mH inductor delivers exceptional signal purity, making it an ideal choice for high-fidelity speaker systems where accurate frequency division is critical. Its air core construction eliminates core saturation and hysteresis distortion, ensuring transparent sound reproduction across the entire audio spectrum.

This coil excels in passive crossover networks for two-way and three-way speaker designs, particularly in high-end home audio, studio monitors, and custom DIY projects. The low DC resistance of 0.72 Ω minimises power loss and maintains amplifier damping factor, while the ±3% tolerance guarantees consistent performance between matched pairs. With a wire diameter of 1.45 mm (15 AWG), it handles up to 5 watts RMS continuously without overheating.

Measuring 64 x 60 mm, this compact yet robust coil integrates easily into enclosures. The precision-wound air core design ensures stable inductance values over time, preserving crossover accuracy. Whether upgrading existing speakers or building new ones, this Jantzen Audio component provides the reliability and sonic transparency demanded by critical listening applications.
