Iron Core Inductors

Quality iron core inductors begin with quality components. Our solid core inductor coils feature 99.9% pure copper while the cores use low distortion micro-thin laminated steel. All models are wound using precision layering equipment that maintains the crystalline structure of the wire and controls hysteresis tension.

The advanced design of these iron core inductors minimizes core saturation, ensuring that your speaker crossover networks deliver consistent performance even at high power levels for woofer or subwoofer circuits. They are available in multiple power ratings and inductance values so you can build accurate crossover assemblies for your next speaker project.
