Product Sheet 215-2000 mk2

2000 Serie

The Alnico is the oldest type of magnet, along with the Ticonal. It is more sensitive than others to demagnetization, but a rigorous study of the magnetic system makes it possible to fully exploit its qualities: high magnetic force, which is almost insensitive to temperature rise, with an operating limit of 450°C.

The 215-2000, the flagship model of the Supravox range, has been thoroughly revised.

The new Alnico engine, developed using FEA software, has been upgraded from an annular configuration to a one-kilogram core of Alnico5. This arrangement allows to capture 100% of the magnet’s energy. The magnetic field reaches 1.4T in the 8mm air gap.

The new pole profile provides better symmetry of the Bl(x) curve, with a 2.9mm excursion, and generates less distortion.

This new magnetic unit, powerful but compact, releases the rear wave from the loudspeaker.

The mobile crew has been revised, we have brought a new treatment of the cone.

All this work allows us to maintain the qualities of transparency and dynamics, with an even better tonal balance and a significantly reduced distortion.
