High-quality transformer core coil with 4.7 mH for demanding crossovers in PAs. The vacuum-impregnated design ensures very high load carrying capacity and low distortion, while the minimum internal resistance remains stable even at dynamic levels. The enamelled copper wire (CUL) supports reliable heat and long-term resistance. Typical are the impressive electrical properties at 50 Hz as well as a compact design, which is suitable for professional speaker design applications. Technical data
