Hi, thank you for all the comments....
I also called DPA, and the sales man told me after discussion, that I might go with the 4061 to use in a car..... I think I'll make a test with it and then decide.
Thank you again, and if you have any other idea....
P.S. : Mathias, I use Cub 01 for years now, at the begining I was super happy, but I don't know why, today they sound flat. I have a lot of (shhhhhhh.... don,t know the word in english) and regarding my technician, they are fine.... that's why I'd like to try something else, and quicker to fix in a car.
Than you
Arno
