This 6.5-inch black Dragon boat speaker redefines the physical laws of ceiling-mounted speakers with a patented dragon spine reinforcement structure. The three-dimensional crossed alloy frame (resembling a keel) runs through the high-strength cabinet, completely taming the mid and low-frequency resonance and airflow noise, and unleashing the true potential of the 6.5-inch unit. The matte black micro-perforated mask, like a dark night armor, conceals into the ceiling. It houses dual magnetic circuit drive units that have been calibrated for military grade. Specifically designed for 20-40 square meters of commercial Spaces (high-end retail, theme restaurants, hotel lobbies) and panoramic sound audio-visual rooms, it reconstructs the sound energy ratio of the space with superior sound pressure and zero-color purity.

Characteristics and Advantages
Three-directional alloy frame: Cross-supported aviation aluminum keel, the box rigidity is increased by 300%, the box resonance below 180Hz is eliminated, and the common "buzzing sound" in restaurants/exhibition halls is eliminated.
Double helix muffler duct: Backwave airflow offset dissipation technology, wind noise reduced to 19dB SPL@1m, large dynamic music details to the point.
Mid-frequency density revolution: Mineral composite diaphragm + dual neodymium magnet drive, 300-800Hz human voice thickness increased by 40%, sales assistant voice penetration reached STI 0.72 (premium grade).
Low-frequency transient control: 0.35ms response speed (0.8ms for traditional products), the drumbeats are as smooth as electricity, eliminating the turbidity of KTV.
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.
