This 5.25-inch white Dragon boat audio system is the crystallization of acoustic precision and spatial aesthetics. The micro-carved dragon spine frame was injected into the high-density composite cavity to eliminate the medium-frequency resonance with a bending stiffness of 5800N/mm². The silk ball-top high-pitched sound and double folded ring suspension edge technology achieve an anatomically separated human voice and instrumental music. The matte white mesh cover, with a 0.2mm ultra-narrow micro-edge, conceals into the ceiling. It is specifically designed for 15-30 square meters of Spaces such as art galleries, recording monitoring rooms, and high-end retail counters, delivering a pure sound base comparable to that of monitor speakers.

FAQ
1.How do you know if a speaker is powerful?
This is the most reliable measure of a speaker's power-handling capability. It indicates the maximum continuous power a speaker can handle safely. If a speaker has an RMS rating of 50 watts, it means it can handle 50 watts of power continuously without harm.
2.What makes a speaker more powerful?
Specifically, wattage affects volume-at least, kind of. A speaker with a higher wattage isn't necessarily louder than a low-watt version, but it does have the potential to be louder. That's because the high-watt speaker can accept more power.
3.What is the best power for speakers?
On the other hand, between 15 and 30 watts is the ideal range for the wattage of the speaker for home use. The majority of homeowners believe that 20 watts are an appropriate amount.
