AQ's subs are built in China with Chinese parts, With the exception of the Aluminum coils on the HDC4 series which are built in the USA and shipped to China. We are one of the very few companies that are upfront about where our subs are built. That's why I insert the letter C in the sub models. Our amps are built in South Korea. We are able to source top quality parts in China with the exception of the Aluminum coils which we source in America. China is not much different then the USA when it comes to quality sub parts, you get what you pay for. We are a factory direct to enduser company and do not advertise or wish to be dealer based. Dealer markups and advertising account for over 50 percent of the price you pay for dealer based products. Our business plan allows us to use the best parts and production methods available and sell at affordable prices.
