Jantzen Audio 000-8039 | 0,39 mH | 0,11 Ω | 2% | 12 AWG

Achieve precise low-frequency control in your crossover designs with this high-quality copper foil coil from Jantzen Audio. The 000-8039 wax coil is engineered for audiophiles and loudspeaker builders who demand the highest level of component performance. Its primary application lies in high-end passive crossover networks, where it excels at filtering low-frequency signals to ensure clean, accurate bass reproduction. The wax-impregnated construction is particularly beneficial in this context, as it effectively dampens mechanical vibrations and reduces microphonics, which can otherwise colour the sound.

From a technical standpoint, this coil offers an inductance of 0.39 mH with a tight tolerance of ±2%, ensuring consistent performance across production batches. The DC resistance is a mere 0.11 Ω, minimising signal loss and power dissipation. The use of 12 AWG copper foil, with a wire diameter of 2.05 mm, provides excellent current handling and low eddy current losses. The wax coating not only stabilises the winding but also protects against environmental factors. With dimensions of 66 x 55 mm, this component is compact yet robust, making it a reliable choice for demanding audio applications where sonic purity is paramount.
