Dayton Audio LW18-90 | 0.90 mH | 0.48 Ω | 3% | 18 AWG

The Dayton Audio LW18-90 is a precision-engineered air core inductor coil, designed to deliver exceptional crossover filtering in high-fidelity loudspeaker systems. This 0.90 mH component is crafted for audiophiles and DIY speaker builders who demand accurate frequency division and minimal signal degradation. Its air core construction eliminates core saturation and distortion, ensuring pure, uncolored audio reproduction across the entire frequency range.

Ideal for use in two-way or three-way crossover networks, this inductor excels in applications where precise bass management and midrange clarity are critical. Whether you are upgrading existing speakers or building custom designs from scratch, the LW18-90 provides reliable performance in both passive and active crossover configurations. Its low DC resistance of 0.48 Ω ensures efficient power transfer and reduced heat buildup, making it suitable for moderate to high-power systems.

Technically, the coil features an 18 AWG wire diameter of 1.02 mm, wound in a perfect layer pattern to minimize parasitic capacitance and maintain consistent inductance. With a tight tolerance of ±3%, it guarantees accurate crossover points. The compact dimensions of 47 x 17.8 mm allow for easy integration into tight enclosures, while the air core design ensures linearity and long-term stability. Rated for 3 watts RMS, this inductor is a robust choice for demanding audio projects.

Combining meticulous construction with audiophile-grade materials, the Dayton Audio LW18-90 is a reliable building block for achieving transparent, detailed sound in any speaker system.
