Mundorf BL100 air core coil, 8.2mH ±2%, 1.69ohm, 1.00mm 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 L100 air core coil, 0.39mH ±2%, 0.29ohm, 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 CFC16 air copper foil coil, 3.3mH ±2%, 0.74ohm, 17x0.07mm OFC-copper wire, Ø81xH24mm, with backed varnish wire

La bobine série CFC est une self à air constituée d’un enroulement de feuille de cuivre OFC 99.99% séparé par une feuille d’isolation polypropylène de 0.02 mm. La partie centrale est percée pour la fixation.

Mundorf L71 air core coil, 0.18mH ±2%, 0.34ohm, 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.
