Dayton Audio AC20-15 | 0.15 mH | 0.26 Ω | 5% | 20 AWG

The Dayton Audio AC20-15 air core inductor coil is a precision component engineered for audiophiles and speaker builders who demand accurate crossover performance. With a 0.15 mH inductance and a tight ±5% tolerance, this coil ensures reliable frequency separation, allowing tweeters and woofers to operate within their optimal ranges for clean, distortion-free sound reproduction.

Ideal for use in high-fidelity loudspeaker crossover networks, this inductor is particularly suited for DIY speaker projects, repair work, or upgrading existing designs. Its air core construction eliminates core saturation and hysteresis distortion, making it an excellent choice for critical listening applications where signal purity is paramount. Whether you are building a two-way bookshelf speaker or a multi-driver floorstanding system, this coil helps maintain phase coherence and transient response.

Technical features include a 20 AWG wire diameter of 0.81 mm, a DC resistance of just 0.26 Ω, and compact dimensions of 34 x 12.5 mm, allowing easy integration into tight enclosures. The air core design ensures linear performance across a wide frequency range, while the 2-watt RMS power handling suits moderate-level applications. Each coil is wound with precision to maintain consistent inductance values, supporting accurate crossover slopes.

This Dayton Audio AC20-15 air core inductor combines reliable construction with audiophile-grade performance, making it a trusted choice for achieving clear, natural sound in your speaker designs.
