  • The main advantage of earthing is the high power performance with a WIDE RANGE power supply level.
  • Considerable e the output power even with high load values at 16 ohms.
  • With the voltage is 25 volts the maximum power output obtained is about 150 watts. Pretty good.
  • In the bridge mode, the manufacturer does not recommend using the speaker with an impedance of fewer than 8 ohms.
