Dayton Audio LW185 | 5.0 mH | 1.33 Ω | 3% | 18 AWG

The Dayton Audio LW185 is a premium air core inductor engineered to deliver precise and reliable crossover performance in high-fidelity loudspeaker designs. As a perfect layer coil, it ensures consistent inductance and minimal signal distortion, making it an essential component for audiophiles and DIY speaker builders who demand accuracy in their audio systems.

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 tweeters. Whether you are constructing a new set of bookshelf speakers, upgrading an existing design, or restoring vintage audio equipment, the LW185 provides the stable inductance required for clear, natural sound reproduction.

Technically, the LW185 features a 5.0 mH inductance with a tight ±3% tolerance, ensuring consistent performance across production batches. Its DC resistance is a low 1.33 Ω, which minimises power loss and heat generation. The coil is wound with 18 AWG wire (1.02 mm diameter) and measures 57 x 27.6 mm, offering a compact footprint for easy integration into crossover boards. As an air core design, it avoids core saturation and hysteresis distortion, preserving signal purity.

With its robust construction and precise specifications, the Dayton Audio LW185 is a reliable choice for achieving accurate crossover points and enhancing overall sound quality in your speaker projects.
