Mundorf BL71-0,56 0.56 mH MCoil AirCore Baked Varnish Coil

The Mundorf BL71-0,56 is part of the MCoil BL AirCore Baked Varnish range, designed for reliable use in passive crossover components. Its 0.56 mH inductance and ±2% tolerance make it suitable where accurate component values are required in a loudspeaker filter design.

This air-core coil uses an OFC copper SolidCore conductor with a 0.40 mm² cross section, corresponding to AWG 21 and a 0.71 mm wire diameter. The air-core design avoids the use of a magnetic core, while the baked winding fixation helps keep the winding stable in use.

With a DC resistance of 0.64 ohm, the BL71-0,56 gives builders a clearly specified value for integrating it into a crossover layout. It belongs to Mundorf’s selection of precision audio coils, offering a compact option for DIY and replacement projects.

The coil is built on the L3020 coil body and measures Ø30 x H20 mm, making it easy to place on a crossover board where space is limited. Its combination of defined electrical values, OFC copper conductor material and baked construction makes it a practical choice for carefully assembled speaker crossover networks.
