Mundorf BL125 air core coil, 1.2mH ±2%, 0.44ohm, 1.25mm OFC-copper wire, Ø58xH28mm, 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 L50 air core coil, 0.47mH ±2%, 1.08ohm, 0.50mm OFC-copper wire, Ø30xH20mm

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 LL60 litz wire air core coil, 0.82mH ±2%, 0.23ohm, 7x0.6mm wire OFC-copper 99.99% with backed varnish wire, Ø29xL70mm

MCoil Hepta Strand coils unite the tonal clarity, beauty and distortion-free performance of air core coils with the stereophonic spaciousness of tightly-wound coils, alongside the harmonious-warmth and splendid brightness of strand copper wire.

Mundorf BL140 air core coil, 0.27mH ±2%, 0.13ohm, 1.40mm OFC-copper wire, Ø58xH18mm, 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 aronit core coil, 3.9mH ±3%, 0.22ohm, 1.40mm OFC-copper wire, Ø51xH51mm

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.

Mundorf L100 air core coil, 10mH ±2%, 1.91ohm, 1.00mm OFC-copper wire, Ø77xH28mm

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, 22mH ±3%, 2.67ohm, 0.50mm OFC-copper wire, Ø30xH25mm

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.

Mundorf BL71 air core coil, 0.047mH ±2%, 0.14ohm, 0.71mm OFC-copper wire, Ø25xH10mm, 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.
