Jantzen Audio 000-8655 | 1,4 mH | 0,47 Ω | 2% | 16 AWG

The Jantzen Audio 000-8655 copper foil coil represents a meticulous approach to crossover design, offering audiophiles and loudspeaker builders a component that prioritises signal purity and mechanical stability. With an inductance of 1.4 mH and a DC resistance of just 0.47 Ω, this 16 AWG wax coil is engineered for precise filtering in high-fidelity loudspeaker systems, ensuring that frequency division occurs with minimal energy loss or distortion.

This coil is ideally suited for use in passive crossover networks within premium two-way or three-way speaker designs, where accurate bass and midrange driver integration is critical. Its low resistance makes it particularly effective in series with woofers, allowing controlled power delivery while maintaining transient response. The wax impregnation further enhances performance by damping mechanical vibrations, reducing microphonic interference that can colour the audio signal.

Constructed from high-purity copper foil rather than standard round wire, the winding geometry minimises skin effect and eddy current losses, preserving detail across the frequency spectrum. The ±2% tolerance ensures consistent behaviour between channels, while the compact 81 x 25 mm dimensions facilitate straightforward mounting within enclosures. Each coil is hand-crafted to Jantzen Audio’s exacting standards, guaranteeing reliability in long-term use.

For discerning listeners seeking to refine their loudspeaker’s crossover performance, this wax-coated foil coil delivers a measurable improvement in clarity and imaging. It is a worthy investment for any serious DIY audio project.
