Dayton Audio LW142-5 | 2.5 mH | 0.43 Ω | 5% | 14 AWG

The Dayton Audio LW142-5 Perfect Layer Inductor Crossover Coil is a premium air core inductor designed for audiophiles and speaker builders who demand uncompromising performance. With an inductance of 2.5 mH and a DC resistance of just 0.43 Ω, this coil ensures minimal signal loss and accurate crossover filtering in high-fidelity loudspeaker systems.

This inductor is ideally suited for use in passive crossover networks within home audio speakers, studio monitors, and custom DIY designs. Its precise inductance value and tight ±3% tolerance make it perfect for achieving consistent and reliable frequency division, whether you are building new speakers or upgrading existing ones. The air core construction eliminates core saturation and distortion, preserving the purity of the audio signal even at higher power levels.

Technical features include a 14 AWG wire gauge (1.63 mm diameter) wound in a perfect layer configuration, which reduces parasitic capacitance and maintains stable performance across the audio band. The coil measures 78 mm in diameter and 29.2 mm in height, with an RMS power handling of 8 watts. The robust construction and low resistance ensure efficient operation, making this inductor a reliable choice for critical crossover applications.

In summary, the Dayton Audio LW142-5 delivers precise, low-loss performance for discerning audio enthusiasts seeking to optimise their speaker designs with a high-quality air core inductor.
