Dayton Audio IC181 | 1.0 mH | 0.19 Ω | 3% | 18 AWG

The Dayton Audio IC181 is a precision-engineered iron core inductor crossover coil, designed to deliver reliable and accurate frequency filtering in high-fidelity loudspeaker systems. As part of Dayton Audio’s respected range of audio components, this coil is built to meet the demands of both DIY enthusiasts and professional audio engineers seeking consistent performance in their crossover networks.

This 1.0 mH inductor is ideally suited for use in two-way or three-way speaker crossovers, where it helps to separate audio signals and direct the correct frequency ranges to the appropriate drivers. Whether you are building custom speakers from scratch or upgrading an existing design, the IC181 ensures clean, predictable filtering that enhances overall sound quality. Its low DC resistance of just 0.19 Ω minimises signal loss and power dissipation, making it an excellent choice for applications where efficiency and clarity are paramount.

Constructed with 18 AWG wire and a robust iron core, the coil offers a tight inductance tolerance of ±3%, ensuring consistent performance across production units. The iron core design provides high inductance values in a compact form factor, while the 25 W RMS power handling capability allows it to cope with moderate to high power levels without saturation. Each coil is wound with precision to maintain stable electrical characteristics, contributing to a reliable and repeatable crossover response.

With its combination of accurate inductance, low resistance, and durable construction, the Dayton Audio IC181 is a dependable component for any serious loudspeaker project, delivering the performance needed to achieve a well-balanced and natural sound.
