HED - High Energy Design - HED short for High Energy Design are Cerwin Vega's mid-level speakers amplifiers and subwoofers. The HED series are perfect for use when bang for buck is important but you are prepared to pay a tiny bit more for superior build quality materials and construction. For full range speakers that means higher grade tweeter domes and discrete crossovers that are designed to fit even the most confined spaces with ease. For subwoofers that means larger motor structures with higher flux density and higher power handling. For amplifiers that means more complete feature sets superior circuit topologies and higher power outputs. - Cerwin Vega made a name for itself developing ultra-high efficiency subwoofers for the pro audio market way back in the 50s before going on to secure its legacy through the creation of some of the most legendary mobile subwoofers the market has ever seen. Today Cerwin Vega continues its legacy and dominance by combining its historically significant efficiency quality reliability and performance with some of the most sought after developments and technologies to enter the market over the past decade. Never losing sight of their heritage the engineering prowess of Cerwin Vega remains evident in every product they develop to this day.
