Intertechnik HQR32/3.3/60 | 3,3 mH | 1,41 Ω | 5% | 23 AWG

The Intertechnik HQR32/3.3/60 is a premium-quality iron core coil designed to deliver precise and reliable low-frequency filtering in loudspeaker crossover networks. With its robust construction and carefully selected materials, this component ensures consistent performance for demanding audio applications. Ideal for use in two-way and three-way speaker systems, it excels at handling bass and midbass drivers, providing clean signal separation and minimising distortion. Whether you are building custom loudspeakers or upgrading existing designs, this coil offers the stability and accuracy required for high-fidelity sound reproduction.

Technically, the coil features a 3.3 mH inductance with a tolerance of ±5%, ensuring tight control over crossover points. The DC resistance is a low 1.41 Ω, which helps maintain efficiency and reduces power loss. Wound with 23 AWG wire (0.6 mm diameter), it offers excellent current handling. The outer diameter measures 32 mm, with a core diameter of 15 mm and a total height of 26 mm. The winding width is 20 mm, and the coil includes a central hole of 5 mm and a recess diameter of 12 mm for secure mounting. This iron core design provides high inductance in a compact form, making it an excellent choice for audiophile-grade crossover networks where space and performance are equally important.
