Hello I got a composystem from Hertz at Christmas and want to put it so slowly in my Vectra a. With the low midrange driver everything is clear. Thanks to the adapter frame and sheet metal from the door a little water, it fits. But how do I build the tweeter best to have the best sound? The original sits in the amature board left and right under his basket and plays against the windshield. Should I also build the new one under the basket? Or is it better to use the the holder, which are in the process of perhaps installing on the basket? Because these holders are like such a housing and slightly bevelled. Due to the additional slanting the HT ́s would no longer play against the disc probes directly in the inner room. Does this make sound, for the non-professional listener as I am, an advantage? Of the optics it is more beautiful when the HT sits under the basket. What do you mean?
