Jantzen Audio 000-611128 | 2,8 mH | 0,05 Ω | 5% | 12 AWG

The Jantzen Audio 000-611128 toroidal coil is a premium-grade component engineered for high-fidelity loudspeaker crossover networks. This 2.8 mH inductor, with an exceptionally low DC resistance of just 0.05 Ω, ensures minimal power loss and superior signal integrity, making it an ideal choice for audiophiles and professional speaker builders seeking accurate, transparent sound reproduction.

This coil excels in demanding audio applications, particularly within passive crossover designs where precise frequency filtering is critical. Its low resistance makes it especially suitable for woofer and midrange circuits, allowing for efficient power handling and tight bass control. The toroidal construction also makes it perfect for use in compact enclosures where space is at a premium, as its flat, donut-shaped profile fits neatly onto crossover boards.

Technically, the coil features a 12 AWG (2.05 mm) copper wire wound on a toroidal core, which inherently cancels external magnetic fields and reduces hum pickup. The inductance value of 2.8 mH is held to a tight ±5% tolerance, ensuring consistent performance across production units. Measuring 95 mm in diameter and 32 mm in height, this robust component is designed for reliable, long-term operation in high-quality audio systems.

For your next high-end speaker project, this Jantzen Audio toroidal coil delivers the precision and low-loss performance required to achieve a clean, dynamic, and musically engaging soundstage.
