Jantzen Audio 000-7415 | 1,0 mH | 0,27 Ω | 2% | 14 AWG

The Jantzen Audio 000-7415 Cross Foil Coil represents a significant upgrade for any serious loudspeaker crossover design. Meticulously engineered from high-purity copper foil rather than standard wire, this air core inductor delivers a level of sonic transparency and detail that discerning audiophiles will immediately appreciate. Its primary application is in high-end passive crossover networks, where it excels at filtering frequencies with exceptional precision and minimal signal degradation.

This coil is ideally suited for use in the low-pass section of a two-way or three-way speaker system, or anywhere that a 1.0 mH inductance value is required. The low DC resistance of just 0.27 Ω ensures that power is transferred efficiently to the drive unit, preserving dynamic impact and control. The ±2% tolerance guarantees that the specified inductance is accurate, which is critical for maintaining the intended crossover point and phase coherence between drivers.

Technically, the 14 AWG equivalent copper foil construction dramatically reduces skin effect and proximity effect losses compared to conventional round wire coils. This results in a purer, more open soundstage with improved micro-detail retrieval. The robust 69 x 37 mm body is wound on a non-magnetic former, ensuring stable performance over time. For the builder seeking the ultimate in crossover componentry, this Jantzen Audio foil coil offers a measurable and audible step forward in performance.
