Mundorf LL45 litz wire air core coil, 1.8mH ±2%, 0.56ohm, 7x0.45mm OFC-copper wire, Ø70xH29mm, 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, 22mH ±2%, 5.26ohm, 0.71mm 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 BL100 air core coil, 2.2mH ±2%, 0.77ohm, 1.00mm OFC-copper wire, Ø58xH22mm, 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 BL71, 0.027mH ±2%, 0.1ohm, Ø10xL25mm, with backed varnish

Mundorf CFC16 air copper foil coil, 1mH ±2%, 0.37ohm, 17x0.07mm OFC-copper wire, Ø57xH24mm, 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 L140 air core coil, 1mH ±2%, 0.28ohm, 1.40mm OFC-copper wire, Ø58xH28mm

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, 2.2mH ±2%, 2.47ohm, 0.50mm 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.

Mundorf BL71 air core coil, 2.2mH ±2%, 1.39ohm, 0.71mm 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.
