Intertechnik AT62/180/132 | 1,8 mH | 0,47 Ω | 3% | 16 AWG

The Intertechnik AT62/180/132 air core choke coil is a premium component engineered to elevate the performance of your loudspeaker crossover networks. By eliminating the core material found in iron-core alternatives, this coil virtually eradicates distortion and saturation, ensuring that your audio signal remains pure and uncoloured. This makes it an ideal choice for discerning audiophiles and professional loudspeaker designers who demand the highest level of fidelity from their systems.

This choke coil is perfectly suited for use in high-end passive crossovers, where precise frequency filtering is critical. Whether you are building custom speakers, upgrading existing designs, or repairing vintage audio equipment, the 1.8 mH inductance and low 0.47 Ω DC resistance allow for accurate crossover points and minimal signal loss. The generous 16 AWG wire diameter further reduces resistive losses, making it suitable for both midrange and bass drivers in multi-way systems.

Technically, the coil features a large 62 mm outer diameter and a 28 mm core diameter, wound with 1.32 mm wire to a total height of 41 mm. The winding width of 35 mm and a central hole of 5.3 mm facilitate easy mounting. With a tight tolerance of ±3%, you can rely on consistent performance across production batches. This air core design ensures linear behaviour across the entire frequency range, delivering transparent and dynamic sound reproduction.

For your next high-fidelity project, the Intertechnik AT62/180/132 offers the reliability and sonic purity required to achieve truly exceptional audio results.
