Feron core coil (cfs coil) cfs16 cfs14 cfs12 cfs10

Mundorf Feron core coil made from copper foil

Mundorf, der Spezialist für Spulen und Kondensatoren MCoil Laminated Core Coils made from copper foil combine both the low level output distortions and the low internal resistance of Feron core coils with the high resolution and the great dynamic properties of OFC copper foil.

They are highly suitable to be used in high quality mid frequency crossovers within subwoofer applications. Furthermore, they are distinguished by an excellent value for money ratio as well as by their compact dimensions.

Technical specifications:
Tolerance: max. 3%, typical 1.5%
Copper 99.997% pure
Core material: FERON
Grain-oriented silicon iron 0.35 mm

*) Pmax 8 Ohm is the maximum power that this coil is able to deliver to the bass driver.
The values are valid for free air convection and 20°C. For 4 Ohm speakers this value has to be halved.
