Mundorf LL45 litz wire air core coil, 0.12mH ±2%, 0.12ohm, 7x0.45mm OFC-copper wire, Ø40xH20mm, 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, 2.7mH ±2%, 1.53ohm, 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.

Mundorf BL125 air core coil, 0.22mH ±2%, 0.14ohm, 1.25mm 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 L125 air core coil, 0.39mH ±2%, 0.2ohm, 1.25mm 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 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 BP100 ferrite pipe core coil, 0.68mH ±3%, 0.23ohm, 1.00mm OFC-copper wire, Ø40xH23mm, with backed varnish wire

Mundorf's P series is halfway between the L and H series, with a ferrite core (or aronit for larger models) to find a compromise between low internal resistance, small footprint and price. Ideal in car-audio or sound system. 99.99% OFC copper backed varnish wire, glass fiber reinforced plastic body, ferrite / aronit core.

Mundorf P71 ferrite pipe core coil, 3.9mH ±3%, 1.23ohm, 0.71mm OFC-copper wire, Ø40xH23mm

Mundorf's P series is halfway between the L and H series, with a ferrite core (or aronit for larger models) to find a compromise between low internal resistance, small footprint and price. Ideal in car-audio or sound system.

Mundorf P100 ferrite pipe core coil, 1mH ±3%, 0.32ohm, 1.00mm OFC-copper wire, Ø40xH23mm

Mundorf's P series is halfway between the L and H series, with a ferrite core (or aronit for larger models) to find a compromise between low internal resistance, small footprint and price. Ideal in car-audio or sound system.
