Must know before buying
♦Impedance Matching : Our K-Series amplifier suitable for impedance 4 ohms and above. ♦How to match our amplifier with your speaker ? 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 lowfrequency speaker is larger than that of the full frequency speaker! ♦Does your unit with warranty ? Yes, it's with a 3-year warranty. Please Click here to read the detail.
