Mundorf H71 ferrite core coil, 2.2mH ±3%, 0.37ohm, 0.71mm 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.

Mundorf H50 ferrite core coil, 3.9mH ±3%, 0.96ohm, 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.

Mundorf LL45 litz wire air core coil, 1.2mH ±2%, 0.46ohm, 7x0.45mm OFC-copper wire, Ø70xH29mm, 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 L71 air core coil, 15mH ±2%, 4.3ohm, 0.71mm 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 BL71 air core coil, 1.8mH ±2%, 1.22ohm, 0.71mm OFC-copper wire, Ø40xH20mm, 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 L140 air core coil, 6.8mH ±2%, 0.96ohm, 1.40mm OFC-copper wire, Ø70xH59mm

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, 2.7mH ±2%, 0.52ohm, 7x0.6mm wire OFC-copper 99.99% with backed varnish wire, Ø59xL70mm

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 BL125 air core coil, 4.7mH ±2%, 0.84ohm, 1.25mm OFC-copper wire, Ø77xH28mm, 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.
