Intertechnik I150/15/150 | 15 mH | 0,44 Ω | 5% | 15 AWG

The Intertechnik Iron-Core Rod Coil, model I150, is a high-quality component designed for demanding audio applications. With a substantial 15 mH inductance, this coil is ideally suited for use in passive crossover networks, particularly for low-frequency drivers where precise filtering is essential. Its robust construction ensures stable performance, making it a reliable choice for both DIY enthusiasts and professional speaker builders seeking to refine their designs.

This coil excels in applications requiring accurate bass management, such as in two-way or three-way speaker systems where it can effectively roll off higher frequencies to the woofer. The iron core provides a high inductance value in a compact form factor, while the 1.50 mm copper wire diameter ensures excellent current handling and low resistance. The DC resistance of 0.44 Ω is carefully controlled to minimise power loss and maintain signal integrity, contributing to a clean, dynamic sound.

Technical specifications include an outer diameter of 58 mm, a central hole of 7.9 mm, and a total height of 49 mm, allowing for straightforward mounting. The ±5% tolerance guarantees consistency across units, which is critical for matched crossover networks. Whether you are upgrading an existing system or building from scratch, this Intertechnik coil delivers the precision and durability required for high-fidelity audio reproduction.
