DEI is the mother company. Viper , sidewinder, Python , Wasp, Hornet, DEI audio, Viper audio are all part of theis company. They came out with Directed audio a couple of years ago and is some sick s%$*!!!!. I was talkig with my DEI rep. just before the Viper audio line came out and he said that they took an already rock solid audio line and over built it. Huge power.
