Dayton Audio LW187 | 7.0 mH | 1.62 Ω | 3% | 18 AWG

The Dayton Audio LW187 is a meticulously engineered 7.0 mH air core inductor, designed to elevate the performance of high-fidelity loudspeaker crossover networks. As a perfect layer coil, it delivers consistent, predictable inductance essential for accurate frequency filtering in passive crossover designs.

This inductor is ideally suited for audiophile-grade speaker builds, custom cabinet projects, and upgrading existing crossover circuits where precision and sonic transparency are paramount. Its air core construction eliminates core saturation and distortion, ensuring pure signal transfer even under demanding dynamic conditions. Whether used in a two-way bookshelf speaker or a complex multi-driver system, the LW187 provides the reliable performance required for critical listening applications.

Technically, the coil offers a low DC resistance of just 1.62 Ω, minimising power loss and heat generation. The ±3% tolerance guarantees tight consistency between units, vital for maintaining phase coherence and accurate crossover slopes. Wound with 18 AWG wire (1.02 mm diameter), it handles up to 3 watts RMS continuously. The compact dimensions of 63 x 26.5 mm allow for flexible placement within enclosures. As a genuine Dayton Audio component, it represents a trusted choice for discerning designers and hobbyists alike.

For your next loudspeaker project, the LW187 delivers the precision and quality that define a superior crossover coil.
