Most manufacturers make their boxes in China and Mexico and bring their cheap products here to resell for a higher profit margin. Well when you focus on profit margins the products quality goes way down.Thats a fact. We lead the pack period. We have a different way of applying the carpet to the edges of the enclosures that ensures it will be there a long time. Our subwoofers boxes aresealed not only with wood glue but secondly with siliconized latex. This ensures the most sealed boxes made. Buy China and Mexico goods and your getting screwed.
