Must know before buying:

Full-range speaker [line array speaker, professional speaker]: the power of the power amplifier should be greater than 1.5 times or more;

Subwoofer speaker: The power of the amplifier should be more than 2 times or more, because the current of the low frequency speaker is larger than that of the full frequency speaker!
