3" 4-Layer Black Aluminum Voice Coils Wound with OFC (100% Copper) Wire Made in Japan
The CCAW Wire we use is made in Japan. It is one of the most important components to make the sub high quality and last longer. (Most subs on the market use wire made in China which can not handle nearly as high temperatures as our wire that is made in Japan)

Our cones are ultra-stiff. They are thicker and stronger than other subs on the market making our subs able to handle more power.
