Intertechnik TRI55/1.2/0.50 | 1,2 mH | 0,394 Ω | 1% | 24 AWG

The Intertechnik TRI55/1.2/0.50 Tritec Coil is a premium air core inductor designed for discerning audio enthusiasts and professional speaker builders. This 1.2 mH coil delivers exceptional performance in crossover networks, ensuring precise signal filtering that separates frequencies with remarkable accuracy. By minimising distortion and phase shift, it allows each driver to operate within its optimal range, resulting in a cleaner, more natural soundstage with improved imaging and detail retrieval.

Ideal for high-fidelity loudspeaker designs, this coil excels in both two-way and multi-way crossover applications. Whether you are upgrading an existing system or building a custom pair of speakers from scratch, the TRI55 coil provides the consistency and reliability required for critical audio projects. Its air core construction eliminates core saturation and hysteresis effects, making it particularly suitable for high-power handling and low-distortion applications where sonic purity is paramount.

Technically, the coil features a 1.2 mH inductance with a tight ±1% tolerance, ensuring predictable and repeatable performance across production batches. The 0.394 Ω DC resistance is achieved using 24 AWG wire wound on a 55 mm outer diameter former, with a winding width of 23 mm and a total height of 30 mm. The central bore measures 5.3 mm, while the recess diameter is 25.5 mm, facilitating straightforward mounting. The 0.5 mm wire diameter contributes to efficient current handling, and the robust construction ensures long-term stability.

This Tritec coil from Intertechnik is an excellent choice for those seeking uncompromising quality in their loudspeaker crossover designs, combining precise electrical specifications with the inherent advantages of air core technology.
