Ad information

Crescendo Evolution 712 is 12 inch (30 cm) subwoofer that has double 4 Ohm impedance and works on the range of 300 to 600 Watts. Bass reproduction is low, solid, and easy to blend with front speaker. On top of that, the required box is very small (start from 10 litre) and subwoofer height is only 16 cm, the best match for above spare tire application.

Evolution 712 is designed for competition in Sound Quality category but it can play loud music if we use 2 pieces or more.


Some advance features of Evolution 712 as follows:

  • Abundant source of bass energy is 5 layer 66 mm huge voice coil and 12 pieces of neodymium magnet. As we all know, neodymium magnet  is 8 times stronger than ferrite magnet.
  • Air mover (cone) is made from massive aluminium to minimize distortion and failure.
  • Subwoofer suspension (spider) progressively change from the outer part to the inner part to maintain linear cone movement.
