Intertechnik AT92/470/132 | 4,7 mH | 0,81 Ω | 3% | 16 AWG

The Intertechnik AT92/470/132 air core choke coil is a premium component designed for audiophile-grade loudspeaker crossover networks. Engineered with meticulous attention to detail, this 4.7 mH inductor delivers exceptional signal purity and minimal distortion, making it an ideal choice for discerning audio enthusiasts and professional speaker builders alike. Its robust construction ensures long-term stability and consistent performance in even the most demanding audio systems.

This choke coil is perfectly suited for use in high-fidelity crossover filters, where precise inductance values are critical for accurate frequency division between drivers. Whether you are designing a new pair of bookshelf speakers, upgrading an existing floor-standing system, or building a custom subwoofer crossover, the AT92/470/132 provides the reliability and sonic transparency required to achieve a natural, uncoloured soundstage. It is also an excellent replacement part for restoring vintage loudspeakers to their original performance.

Technically, the coil features an inductance of 4.7 mH with a tight tolerance of ±3%, ensuring consistent behaviour across production batches. The DC resistance is a low 0.81 Ω, minimising power loss and heat generation. Wound with 1.32 mm diameter (16 AWG) wire, it offers excellent current handling. The outer diameter measures 92 mm, with a total height of 39 mm and a winding width of 33 mm. The core diameter is 30 mm, featuring a central hole of 5.3 mm and a recess diameter of 25 mm for secure mounting.

For your next high-performance loudspeaker project, trust the Intertechnik AT92/470/132 air core choke to deliver precise, reliable crossover filtering with uncompromising audio quality.
