Mundorf BL140 air core coil, 2.2mH ±2%, 0.46ohm, 1.40mm OFC-copper wire, Ø70xH29mm, 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.

Air core coil Mundorf L200, 4.7mH ±2%, 0.45ohm, 105x93xH79mm

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 L125 air core coil, 1.5mH ±2%, 0.47ohm, 1.25mm OFC-copper wire, Ø58xH28mm

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 H71 ferrite core coil, 4.7mH ±3%, 0.58ohm, 0.71mm 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 LL45 litz wire air core coil, 3.3mH ±2%, 0.93ohm, 7x0.45mm OFC-copper wire, Ø70xH59mm, with backed varnish wire

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 L125 air core coil, 3.9mH ±2%, 0.75ohm, 1.25mm OFC-copper wire, Ø70xH29mm

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 H71 ferrite core coil, 12mH ±3%, 1.02ohm, 0.71mm OFC-copper wire, Ø35xH25mm

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 BL100 air core coil, 8.2mH ±2%, 1.69ohm, 1.00mm OFC-copper wire, Ø70xH29mm, 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.
