First of all, I want to give you a description. I have a preliminary understanding of each part of the speaker:
Super high sound: responsible for frequencies above 22kHz
Treble: Responsible for 5000Hz~22kHz frequency.
Midrange: responsible for 1500~5000Hz frequency
Bass: responsible for frequencies below 1500Hz
Subwoofer (increased) is responsible for frequencies below 200Hz
Splitter: The specified frequency is assigned to each unit to work.
Speaker: divided into sealed, inverted and labyrinth
With many years of dedicated R&D in the lighting technology field, Win 3 produces mining Cap Lamps that reduce visual fatigue while maintaining high light output levels.
With the classsic clip, Win3 cap lamps can be attached to hard cap, helmet, headband etc, which is suitable for professional works and outdoor sports, like coal miners, tunnel projects, mine, oil field construction site, camping, etc.
We have cap lamps in operation for many years at some of the biggest global mining companies like Codelco, Lonmin and Sasol. All with great success.
