Intertechnik LU120/8.2/20 | 8,2 mH | 0,62 Ω | 3% | 12 AWG

The Intertechnik LU120/8.2/20 is a premium air core coil designed for audiophiles and loudspeaker builders who demand uncompromising performance. This 8.2 mH inductor is engineered to deliver precise crossover filtering in high-end speaker systems, ensuring that each driver receives only the frequencies it was intended to handle. Its low DC resistance of just 0.62 Ω minimises signal loss and power dissipation, making it ideal for use in passive crossover networks for bookshelf speakers, floor-standing towers, and studio monitors. Whether you are upgrading an existing design or building a custom loudspeaker from scratch, this coil provides the accuracy and reliability required for critical audio applications.

Technically, the LU120/8.2/20 is wound with 12 AWG wire, offering a generous cross-sectional area that reduces resistive losses and improves current handling. The air core construction eliminates core saturation and hysteresis distortion, preserving signal purity across the entire frequency range. With a tolerance of ±3%, this coil ensures consistent performance from unit to unit. The outer diameter measures 120 mm, with a winding width of 71.5 mm and a total height of 80 mm, while the central hole diameter is 5.3 mm for secure mounting. The recess diameter of 41.5 mm and core diameter of 49.5 mm facilitate integration into your crossover layout. This robust component is built to last, delivering transparent, distortion-free sound for years to come.
