Dayton Audio IC189 | 9.0 mH | 0.72 Ω | 3% | 18 AWG

The Dayton Audio IC189 is a precision-engineered iron core inductor crossover coil, designed to deliver accurate and reliable frequency filtering in high-fidelity loudspeaker systems. With a substantial 9.0 mH inductance and a low DC resistance of just 0.72 Ω, this component ensures minimal signal loss and efficient power handling, making it an excellent choice for audiophiles and custom speaker builders alike.

This inductor is ideally suited for use in passive crossover networks, where it helps to separate audio frequencies and direct them to the appropriate drivers—such as woofers, midrange units, or subwoofers. Its robust iron core construction allows for a compact form factor while maintaining high inductance values, making it particularly effective in low-frequency applications where precise bass management is critical. Whether you are designing a new set of speakers or upgrading an existing pair, the IC189 provides the consistency and performance required for a refined listening experience.

Technically, the coil features an 18 AWG wire diameter of 1.02 mm, wound to a tight tolerance of ±3%, ensuring that each unit performs within a narrow specification range. The iron core design offers excellent saturation characteristics and thermal stability, with a power handling capacity of 25 watts RMS. This combination of low resistance, precise inductance, and robust construction makes the Dayton Audio IC189 a dependable choice for achieving clean, accurate sound reproduction in any high-quality audio project.
