The PC subwoofers have even more to tell than what meets the naked eye… The wild-looking dust-cap is not just four visual pleasures but also acts as a heatsink to extract heat from the coil gap. It is also embedded into the cone’s recesses, stiffens the cone for durability, and eliminates cone flex, which causes radiated noise. All in all, this subwoofer results from strong engineering and dedication to the competitor in all of us.
