Mundorf BL71 air core coil, 0.01mH ±2%, 0.06ohm, 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 BL125 air core coil, 0.56mH ±2%, 0.24ohm, 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.

Mundorf LL60 litz wire air core coil, 1mH ±2%, 0.27ohm, 7x0.6mm wire OFC-copper 99.99% with backed varnish wire, Ø28xL77mm

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, 3.9mH ±2%, 1.91ohm, 0.71mm 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.
