Crescendo Evolution 110 – 2 or 4 ohm is 10 inch (25 cm) subwoofer that has 2 or 4 ohm impedance and works on the range of 200 to 400 Watts. Bass reproduction is low and punchy as to match any kind of music. On top of that, the box size is small (start from 15 litre) thus will not occupy much of the interior space.

Evolution 110 – 2 or 4 ohm is designed to move 21 mm back and forth without distortion, therefore the bass reproduction is loud.

Some advance features of Evolution 110 2 or 4 ohm as follows:

• Abundant source of bass energy is 4 layer 50 mm large voice coil and double 135 mm large magnet.
• Custom made chassis creates maximum ventilation to cool down voice coil and avoid distortion.
