The C-Coil is not recommended for any other use than on crossovers for passive loudspeakers.
This is due the the toroidal core’s strong output of electromagnetism.
These coils are not suitable for installation in amplifiers or active systems.
We do not recommend use of C-Coils on crossovers with an XO point above 1.20 kHz.
If the stated maximum wattage is not exceeded the core will never saturate.
The C-Coil is designed for the bass section of crossovers and for passive Sub-Woofers.
