Mundorf BL100 air core coil, 0.33mH ±2%, 0.26ohm, 1.00mm 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 L140 air core coil, 1.5mH ±2%, 0.38ohm, 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.

Transformer-core T200 Mundorf coil 1.2 mH

The Mundorf T-series uses a round 99.99% OFC solid copper conductor, wrapped around a glass-fiber reinforced plastic backing, which is placed on an iron-silicon alloy structure to enhance the magnetic field. The T series is particularly suitable for filtering woofers in a precise and powerful way.

Mundorf CFC16 air copper foil coil, 0.12mH ±2%, 0.11ohm, 17x0.07mm OFC-copper wire, Ø35xH24mm, 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 L50 air core coil, 0.33mH ±2%, 0.78ohm, 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 BL71 air core coil, 0.33mH ±2%, 0.47ohm, 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 BL180 air core coil, 3.3mH ±2%, 0.42ohm, 1.80mm OFC-copper wire, L89xH61xZ76mm, with backed varnish wire

Mundorf CFC18 air copper foil coil, 1.2mH ±2%, 0.55ohm, 11.5x0.07mm OFC-copper wire, Ø57xH18mm, 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.
