Mundorf BL125 air core coil, 6.8mH ±2%, 1.19ohm, 1.25mm OFC-copper wire, Ø70xH59mm, with backed varnish wire

The BL series from Mundorf uses the same coils as the L series but with the addition of a stabilization varnish considerably reducing electromagnetically induced vibrations. If your passive filter concerns a high-end speaker, the choice of a BL coil instead of an L coil is a relevant choice because it directly impacts the listening quality.

Mundorf H140 ferrite core coil, 1.2mH ±3%, 0.09ohm, 1.40mm OFC-copper wire, Ø40xH37mm

MCoil Drum-Core coils made from oxygen-free copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.

Air core coil Mundorf L100, 2mH ±2%, 0.74ohm, Ø22xL58mm

Mundorf's L series uses a 99.99% solid OFC round copper conductor, specially developed for high quality filtering. The winding stand is made of glass fiber reinforced plastic. The L-series coil is the standard for quality passive filtering.

Mundorf H50 ferrite core coil, 4.7mH ±3%, 1.06ohm, 0.50mm OFC-copper wire, Ø26xH25mm

MCoil Drum-Core coils made from oxygen-free copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.

Air core coil Mundorf L50, 6.8mH ±2%, 4.7ohm, Ø20xL40mm

Mundorf's L series uses a 99.99% solid OFC round copper conductor, specially developed for high quality filtering. The winding stand is made of glass fiber reinforced plastic. The L-series coil is the standard for quality passive filtering.

Air core coil Mundorf L140, 12mH ±2%, 1.35ohm, 89x76xH61mm

Mundorf's L series uses a 99.99% solid OFC round copper conductor, specially developed for high quality filtering. The winding stand is made of glass fiber reinforced plastic. The L-series coil is the standard for quality passive filtering.

Mundorf BH180 aronit core coil, 0.39mH ±3%, 0.04ohm, 1.80mm OFC-copper wire, Ø51xH51mm, with backed varnish wire

MCoil Drum-Core backed varnish coils made from oxygen-free copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.

Mundorf BL100 air core coil, 0.1mH ±2%, 0.14ohm, 1.00mm OFC-copper wire, Ø30xH20mm, with backed varnish wire

The BL series from Mundorf uses the same coils as the L series but with the addition of a stabilization varnish considerably reducing electromagnetically induced vibrations. If your passive filter concerns a high-end speaker, the choice of a BL coil instead of an L coil is a relevant choice because it directly impacts the listening quality.
