The Intertechnik LU44/2.70/071 is a precision-engineered 2.7 mH air core coil, designed to deliver accurate and reliable performance in high-fidelity loudspeaker crossover networks. As part of Intertechnik’s respected range of audio components, this coil is ideal for audiophiles, speaker builders, and repair technicians seeking consistent, distortion-free filtering.

This air core coil is particularly well-suited for use in passive crossover designs, where it helps to separate frequency bands with minimal signal degradation. Its non-inductive core eliminates the risk of saturation, making it an excellent choice for high-power applications and critical listening environments. Whether you are constructing a new set of bookshelf speakers or upgrading an existing system, this coil ensures clean, transparent sound reproduction.

Technically, the coil offers an inductance of 2.7 mH with a tight ±3% tolerance, guaranteeing uniformity across multiple units. The DC resistance is a low 1.62 Ω, which helps maintain system efficiency. Wound with 21 AWG wire (0.71 mm diameter), it features an outer diameter of 44 mm, a recess diameter of 12 mm, and a central hole of 5.3 mm for straightforward mounting. The robust construction and precise winding ensure long-term stability and consistent performance.

In summary, the Intertechnik LU44/2.70/071 air core coil is a dependable choice for anyone serious about speaker crossover design, offering technical precision and sonic transparency at a competitive price point.
