Jantzen Audio 000-1043 | 4,43 mH | 1,24 Ω | 3% | 18 AWG

The Jantzen Audio 000-1043 air core coil is a precision component designed for audiophiles and speaker builders who demand accurate crossover filtering. This 4.43 mH inductor, wound with 18 AWG wire, delivers reliable performance for high-fidelity audio systems, ensuring clean signal separation between drivers. Its air core construction eliminates core saturation and distortion, making it ideal for critical listening environments where sound purity is paramount.

This coil excels in passive crossover networks for two-way or three-way speaker designs, particularly in high-end home audio and studio monitor applications. It is also suitable for custom audio projects requiring consistent inductance values, such as equalisers or impedance correction circuits. The ±3% tolerance guarantees tight matching between channels, preserving stereo imaging and tonal balance.

Technical features include a low DC resistance of 1.24 Ω, which minimises power loss and maintains driver damping factor. The 1.02 mm wire diameter (18 AWG) offers a good balance between current handling and compact winding. Measuring 57 x 30 mm, the coil fits neatly into most crossover boards. The air core design ensures linear performance across the audio frequency range, with no hysteresis or eddy current losses.

For discerning audio enthusiasts, this Jantzen Audio coil provides the precision and sonic transparency needed to elevate speaker designs. Its robust construction and tight specifications make it a reliable choice for both new builds and upgrades.
