Oklahoma City, OK, May 5, 2016 -- DD Audio is celebrating 30 years of bass "domination" by taking dealers on a journey through the world-renowned 9500 Series evolution.

From the beginning, DD has continually worked to improve our designs to keep up with the newest technology and the ever changing styles of music flowing through our veins. This comprehensive list documents each model’s highlights, changes, and improvements.

With each new model DD Audio was able to push new limits, and thus, continually increase the performance and durability of the product.The company has learned over the years, and each lesson has helped pave the way to its newly released 9500 ESP subwoofers.
