The VD Series by Skar Audio were designed to be a very versatile and powerful subwoofer. When space or mounting depth is an issue, look no further. The VD 15 woofer is extremely powerful, rated at a conservative 500 Watts RMS power, and feature a high quality 2 Basv voice coil. Furthermore, the VD Series utilize only the best parts, such as a competition grade cone, high strength foam surround, and a 2 Layer Conex spider for high power handling. These components in conjunction with the advanced cooling design of this woofer allow it to fit in much shallower enclosures, yet allow it to perform with attitude.
