ESX
ESX Automotive Audio is the manufacturer of the best car audio speakers and amplifiers possible. Their products are assorted into product categories, each serving a unique need. When we look at their most successful products, such as QUANTUM 1 and VISION 1, the company's maestri over car audio equipment becomes evident. The brand was eventually taken over by Audio Design GmbH, a German audio firm, which only served to improve the products' quality.
