Not sure but with a little searching on the 2 model numbers you can find out pretty easy. I think that DDX-6019 is the unit that 2manytrucks has. I liked his so I went and found the DDX-7017 but mines not the Excelon series. I know one of the differences with the Excelon is that it offers the 5.1 surround center channel speaker too.Originally Posted by Black 2003
