Mundorf BL140 air core coil, 0.15mH ±2%, 0.1ohm, 1.40mm 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 H50 ferrite core coil, 12mH ±3%, 1.75ohm, 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 L71 air core coil, 2.2mH ±2%, 1.39ohm, 0.71mm 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.

Zero-mH N250 Mundorf coil 33 mH

33mH ±5% ; RDC 0.22ohm ; Body N130 ; Wire Ø2.5 mm

Mundorf L140 air core coil, 1.2mH ±2%, 0.31ohm, 1.40mm 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 H125 ferrite core coil, 3.9mH ±3%, 0.24ohm, 1.25mm 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 BL71 air core coil, 0.27mH ±2%, 0.42ohm, 0.71mm 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 BL125 air core coil, 0.68mH ±2%, 0.28ohm, 1.25mm 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.
