Coils

Mundorf L100 air core coil, 0.56mH ±2%, 0.36ohm, 1.00mm OFC-copper wire, Ø40xH20mm

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 BL125 air core coil, 0.1mH ±2%, 0.09ohm, 1.25mm 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.

Mundorf BL140 air core coil, 6.8mH ±2%, 0.96ohm, 1.40mm 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.

iCore feron coil Mundorf BS140, 5.6mH ±3%, 0.25ohm, 106x32xH32mm

Mundorf's BS series uses a solid 99.99% OFC copper round conductor stabilized by varnish, wrapped around a rod-shaped iron-silicon alloy core. Each end of the stick is fitted with a hole for attachment.

Mundorf H71 ferrite core coil, 18mH ±3%, 1.28ohm, 0.71mm 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.

Mundorf L71 air core coil, 0.27mH ±2%, 0.42ohm, 0.71mm 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 BL71 air core coil, 12mH ±2%, 3.65ohm, 0.71mm 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.

Mundorf L140 air core coil, 0.12mH ±2%, 0.08ohm, 1.40mm OFC-copper wire, Ø40xH20mm

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.
