Black Hydra HDC-2.25 6.5" 150W Max 2-Way 4-Ohm Component Speaker System

The woofer cone is made of thermally dried pulp with a special impregnating composition, which reduces the resonance processes in its structure, due to the increase in internal losses. In combination with a surround made of styrene-butadiene rubber, which has a low mechanical loss ratio, it helps minimize parasitic noise caused by resonant vibrations of the moving system.

25mm tweeter with a dome made of silk, allows you to shift the crossover frequency by about 1 octave, which leads to redistribution of acoustic energy between the woofer and tweeter, making the sound more aggressive and dynamic.
