Black Hydra HGS-2521

The voice coil frame is made of black aluminum, which allows additional heat dissipation and avoids the effect of temperature compression.
The motor, the bead and the spider of the Black Hydra HGS-2521  ensure a linear movement of the diaphragm within 24 mm with a soft limitation when the operating conditions are exceeded. This minimizes distortion at normal and high volume levels and eliminates the possibility of mechanical damage to the loudspeaker under extreme operating conditions.
The motor uses ferrite magnets of the highest quality with excellent stability and repeatability of its parameters.
The ability of the Black Hydra HGS-2521 subwoofers The ability to work in compact acoustic enclosures and the installation depth of only 136 mm make the Black Hydra HGS-2521 an ideal choice not only for installation in classic enclosures, but also in stealth enclosures when free space is limited. The optimal power of amplifiers for operation with the Black Hydra HGS-2521 is 300-600 watts.
