Mundorf BL71 air core coil, 0.1mH ±2%, 0.23ohm, 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.

Mundorf H140 ferrite core coil, 1.2mH ±3%, 0.09ohm, 1.40mm 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 VLCU18 paper air copper foil coil, 0.1mH ±2%, 0.13ohm, 11.5x0.07mm OFC-copper wire, Ø34xH18mm, with vaccum impregnated wire

OFC copper tape coil 99.997%, 70µ thickness, insulated with a sheet of 30µ paper (Abacá Esparto) impreganted with a viscoplastic insulating resin. It is obtained a high mechanical damping of vibrations, almost without microphonic effect, even without housing. Extremely calm acoustic model and the finest micro-dynamics. This series makes it possible to move upmarket compared to the famous CFC series from Mundorf.

Mundorf L140 air core coil, 0.39mH ±2%, 0.16ohm, 1.40mm OFC-copper wire, Ø58xH18mm

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, 0.27mH ±2%, 0.15ohm, 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.

Air core coil Mundorf L50, 6.8mH ±2%, 4.7ohm, Ø20xL40mm

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 L50 air core coil, 0.27mH ±2%, 0.67ohm, 0.50mm OFC-copper wire, Ø25xH10mm

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 H100 ferrite core coil, 2.7mH ±3%, 0.24ohm, 1.00mm 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.
