Intriguing from the first look, the new PC subwoofers have even more to tell than what meets the naked eye... The wild looking dustcap is not just four visual pleasure, but also acts as a heatsink to extract heat from the coil gap. It is also embedded into recesses in the cone and stiffens the cone for durability and to eliminate cone flex which cases radiated noise. All in all, this subwoofer is a result of strong engineering and dedication to the competitor in all of us...
