Dayton Audio LW18-05 | 0.05 mH | 0.10 Ω | 5% | 18 AWG

The Dayton Audio LW18-05 is a precision air core inductor coil, meticulously engineered to elevate the performance of your loudspeaker crossover networks. This component is essential for audiophiles and DIY speaker builders seeking to achieve accurate frequency division, ensuring that each driver receives only the signals it is designed to handle. By using this coil, you can significantly improve the clarity and definition of your sound system, reducing distortion and creating a more immersive listening experience.

This inductor is ideally suited for use in high-fidelity crossover designs, particularly for tweeter and midrange circuits where precise filtering is critical. Its low inductance value of 0.05 mH makes it perfect for applications requiring a gentle roll-off or for use in series with a capacitor to create a notch filter. Whether you are building a new set of bookshelf speakers or upgrading an existing pair, this coil provides the reliability and performance demanded by serious audio projects.

Technically, the LW18-05 features a 1.02 mm (18 AWG) wire winding, which results in an exceptionally low DC resistance of just 0.10 Ω. This minimises signal loss and power dissipation, maintaining the integrity of your audio signal. The coil is wound as a perfect layer air core design, eliminating core saturation and hysteresis distortion. With a tight tolerance of ±5% and compact dimensions of 32 x 16.2 mm, it integrates easily into most crossover boards. Rated for 3 watts RMS, it offers robust performance for a wide range of speaker systems.

In summary, the Dayton Audio LW18-05 air core inductor is a high-quality, reliable component that delivers precise crossover performance, making it an excellent choice for any discerning audio enthusiast.
