Intertechnik AT92/330/132 | 3,3 mH | 0,66 Ω | 3% | 16 AWG

The Intertechnik AT92/330/132 air core choke coil is a precision component designed for audiophile-grade loudspeaker crossover networks. Engineered for high-fidelity audio systems, this 3.3 mH coil delivers accurate filtering to ensure clean signal separation between drivers, enhancing overall sound clarity and imaging.

Ideal for DIY speaker builders and professional audio engineers, this choke coil excels in crossover designs for two-way and three-way systems. Its air core construction eliminates core saturation and distortion, making it perfect for critical listening environments where linearity and low harmonic distortion are paramount. Whether upgrading existing speakers or building custom enclosures, this coil provides reliable performance across a wide frequency range.

Technically, the coil features a 3.3 mH inductance with a tight ±3% tolerance, ensuring consistent results. The 16 AWG (1.32 mm) wire diameter offers low DC resistance of just 0.66 Ω, minimising power loss. With an outer diameter of 92 mm, a winding width of 33 mm, and a total height of 39 mm, it fits comfortably in most crossover boards. The 30 mm core diameter and 5.3 mm centre hole facilitate secure mounting.

Combining robust construction with precise electrical characteristics, this Intertechnik air core coil is a reliable choice for achieving transparent, high-resolution audio reproduction in any serious loudspeaker project.
