Product description:
The main technical parameters:
1. Dimensions (L*W*H): 83 x 83 x 30 mm (not including the protruding part of the switch socket)
2. Operating voltage range: DC single power supply 12-24V (current 3-4A, or 19-24V/4-5A, such as high power requirements 20-24V/8-9A above)
3. Audio input sensitivity: 600-800mV
4. Frequency response range: 20Hz-20KHz
5. Speaker impedance: 2-8ohm
6. Output power:
Power Supply 12V/8O Europe Speaker >10W/4O>20W/3O>25W/2O>30W (left and right channels same); 19V/8O >24W/4O>45W/3O>60W/2O>75W;
24V/8O >35W/4O>75W/3O>95W;
This is the actual test data on the instrument. The output power is related to the supply voltage current, the speaker impedance, and the input of the audio source.
When the power supply voltage/current is sufficient, the power supply voltage is usually higher and the relative output power can be made larger.
Speakers with different impedances also have different output powers. Generally, the speakers have smaller impedance and more power.
