215-2000 mk2 Fullrange drive unit
35W / 98.5dB / 4 Ohms

1 519,00 TTC

As a best-selling model of the Supravox 215 range of products, the 215-2000 has been thoroughly redesigned in order to come-up with this new improved MKII version.

The new Alnico magnet has been designed under FEA software and allows for an improved homogeneity of the magnetic field and therefore a perfectly symmetrical Bl(x) curve. This allows for a lower distortion. The magnetic field reaches 1,4Tesla in the voice coil gap. This new configuration (from annular to central position of the alnico magnet allows to make use of 100% of the enrgy of the magnet. 

Thnew profile of the central pole allows a better symmetry of the BL(x) curve with +/-2.9mm excursion.

This new magnetic engine, powerfull yet compact allows for a better clearance of the back of the cone. Treatment of the cone has also bee refined.

All this work allows for extreme transparency and clarity, high dynamics and improved, and more balanced tonal characteristics as well as reduced distortion.

Description

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.
