Intertechnik I150/22/150 | 22 mH | 0.56 Ω | 5% | 15 AWG | I-Point Coil

The Intertechnik Iron-Core Rod Coil, with an inductance of 22 mH and a DC resistance of just 0.56 Ω, is a premium component designed for audiophiles and loudspeaker builders who demand precise low-frequency filtering in their crossover networks. This coil excels in high-quality passive crossover designs, particularly for woofer and subwoofer circuits where accurate bass management is essential. Its robust construction ensures reliable performance in both DIY speaker projects and professional audio applications, making it an ideal choice for upgrading existing systems or building new loudspeakers from scratch.

Technically, this coil features a copper wire diameter of 1.50 mm, which contributes to its low resistance and excellent current handling capabilities. The outer diameter measures 58 mm, with a central hole of 7.9 mm and a total height of 49 mm, allowing for straightforward mounting on standard crossover boards. The ±5.0% tolerance ensures consistent performance across production batches, while the iron-core design provides high inductance values in a compact form factor. With a DCR of 0.56 Ω, this coil minimises power loss and maintains signal integrity, delivering clean, uncoloured bass response. Whether you are refining a two-way monitor or a multi-way floorstanding speaker, this Intertechnik rod coil offers the reliability and sonic accuracy required for critical audio applications.
