Intertechnik AT62/150/132 | 1,5 mH | 0,43 Ω | 3% | 16 AWG

The Intertechnik AT62/150/132 air core choke coil is a premium component designed for audiophile-grade loudspeaker crossover networks. Its 1.5 mH inductance and exceptionally low 0.43 Ω DC resistance ensure minimal signal loss, preserving the clarity and detail of your audio reproduction. This coil is ideal for use in high-fidelity speaker builds, studio monitors, or custom crossover upgrades where precise frequency filtering is paramount.

Engineered with a 16 AWG wire diameter of 1.32 mm, this choke coil offers robust current handling and thermal stability. The 62 mm outer diameter and 41 mm total height accommodate a generous winding width of 35 mm, while the 28 mm core diameter and 5.3 mm centre hole facilitate straightforward mounting. The recess diameter of 25.5 mm allows for flush installation in baffles or crossover boards. With a tight tolerance of ±3%, each coil delivers consistent, repeatable performance, critical for maintaining phase coherence and accurate crossover points.

Whether you are designing a two-way bookshelf speaker or a complex multi-way system, this Intertechnik air core coil provides the reliability and sonic transparency demanded by discerning enthusiasts. Its non-saturating air core design eliminates core losses, ensuring distortion-free operation across the audio band.
