Definitions

  • the bass weight of this invention is the most effective in the bass sound section, with the hint that even if you use a threaded phone, it is better to stretch the thread with a bean and the sound will be transmitted better.
  • the conventional cone configuration has a low-frequency range that cannot be found in the eddy on the outer periphery of the cone. In frequency, like the first drum, there was no tension, which inevitably caused attenuation.
  • the main feature is the feature that 100% of the potential of a conventional speaker cone is exhibited in a woofer.
  • the best condition for attaching the bus weight to the cone is a hard, dry adhesive, with a dome-shaped, ring-shaped path weight and a dome-shaped tall object.
