The C-Coil is wound around a toroidal sandwich core, and it has extremely low resistance and can shift a large amount of power without getting over heated.
The core is formed like a donut with a round cross section, and it is wound from one long piece of laminated steel tape.
The surface of the core is epoxy coated to secure against short circuit even at a very high load.

The C-Coil is designed for the bass section of crossovers and for passive Sub-Woofers, available in different core and wire sizes.

We use 4N copper wire for C-Coils
