Pipe core coil Mundorf H71, 2mH ±3%, 0.35ohm, Ø25xL26mm

MCoil Drum-Core coils made from oxygen-free copper (OFC) round-wire have been developed for mid, low and parallel applications for which compact dimensions, a low basic distortion level as well as the lowest possible internal resistance and a reasonable value for money ratio are of key importance.

Mundorf BS125 feron core coil, 6.8mH ±3%, 0.35ohm, 1.25mm wire OFC-copper 99.99% with backed varnish wire, feron core (iCore), 96x32xH32mm

Mundorf's BS series uses a solid 99.99% OFC copper round conductor stabilized by varnish, wrapped around a rod-shaped iron-silicon alloy core. Each end of the stick is fitted with a hole for attachment.

Air core coil Mundorf BL140, 2mH ±2%, 0.43ohm, Ø29xL70mm, with backed varnish

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.
