Jantzen Audio 000-2478 | 3,0 mH | 0,23 Ω | 3% | 15 AWG

The Jantzen Audio 3.0 mH iron core coil is a premium-grade component engineered for high-fidelity loudspeaker crossover networks. Designed to deliver accurate and stable inductance, this inductor ensures precise frequency filtering, which is essential for achieving balanced and natural sound reproduction in both DIY and professional audio projects. Its robust construction makes it ideal for use in passive crossover designs for bookshelf speakers, floor-standing towers, and subwoofer systems where reliable performance is paramount.

Featuring a low DC resistance of just 0.23 Ω, this coil minimises signal loss and power dissipation, allowing more energy to reach the drivers for improved efficiency and dynamic response. The ±3% tolerance guarantees consistent inductance values, critical for maintaining crossover accuracy across production batches. Wound with 15 AWG wire (1.45 mm diameter), the coil handles higher currents with ease, reducing the risk of saturation and distortion. The iron core construction provides high inductance in a compact form factor, measuring 35 x 70 mm, making it suitable for space-constrained enclosures. Whether you are upgrading an existing design or building from scratch, this Jantzen Audio inductor offers the reliability and sonic transparency demanded by discerning audiophiles.
