215-2000
Full range drive unit
The 215-2000 is a full range speaker and high efficiency driver unit. No compromise for this loudspeaker of exception: hyperbolic cone paper without bicone, suspension with the max. displacement of 2cm, Alnico driving block (3.5Kg) and pure iron core to obtain 21000 Gauss of magnetic field. The 215-2000 astonishes by its precision and its clearness in the medium, by the presence without aggressiveness of high frequencies, by the speed and the clearness of its low register, the whole with exceptional dynamics. In column TQWT or in enclosure of back horn type, it justifies its row of ultimate full range loudspeaker.
