Description

2000 Series

The SUPRAVOX 2000 series drivers are equipped with Alnico motors.  

The 380-2000 is a low register driver unit of high efficiency  (97 dB), it is the replacement of the 400-2000: the ultimate driver for the demanding music lover.

It covers 30-600Hz in 280L tuned at 28Hz (two or three 160mm diameter PVC vents).

Its new Alnico motor, assembled around a central magnet of one kilogram of Alnico V, uses a 20mm flat copper wire coil wound on a field, on a ventilated support in glass fibre reinforced Kapton, associated to a profiled core, this assembly offers a perfectly symmetrical travel of +/- 7mm.

Two aluminum demodulating rings stabilize the motor field, but also reduce, linearize and symmetrize the Le(x).

The moving parts take advantage of our new exponential cone, this one by the formulation of its paper offers a better damping which guarantees clarity and definition, while ensuring by its profile a greater rigidity offering a reduced distortion in the low register.

This brand new loudspeaker surpasses our 400-2000, and sets itself as a reference in high-fidelity: bandwidth, linearity of response, clarity of sound, dynamic range, thermal and mechanical resistance, very low distortion.
