Dayton Audio LW18-15 | 0.15 mH | 0.18 Ω | 5% | 18 AWG

The Dayton Audio LW18-15 Perfect Layer Inductor Crossover Coil is a high-quality air core inductor designed to deliver precise frequency filtering in speaker crossover networks. With an inductance of 0.15 mH and a DC resistance of just 0.18 Ω, this coil ensures minimal signal loss and maintains audio clarity, making it an excellent choice for audiophiles and DIY speaker builders alike. Its 18 AWG wire and perfect layer winding technique contribute to consistent performance and low distortion.

This inductor is ideal for use in two-way or three-way crossover designs, where accurate frequency division is critical for achieving balanced sound reproduction. Whether you are upgrading existing speakers or building custom enclosures, the LW18-15 provides reliable filtering for tweeters, midrange drivers, and woofers. Its compact dimensions of 37 x 12.8 mm allow for easy integration into tight enclosures without compromising performance.

Technically, the coil features a ±5% tolerance, ensuring tight adherence to specified inductance values. The air core construction eliminates core saturation and hysteresis distortion, preserving signal integrity even at higher power levels. With a power handling capacity of 3 watts RMS, this inductor is suited for moderate-power applications. The 1.02 mm wire diameter and low resistance further enhance efficiency, making the LW18-15 a dependable component for precise crossover design.
