I would like to buy the Eisenmann system (completely) either in level 2 (sound) or level 3 (super sound) . The question now: Who has experiences to “his”. Is level 3 too loud or too annoying at all? (I imagine an hour ago highway with only “roof” is not exactly advantageous…) Or is this system not so “smooth”? Maybe the one or the other can make it easier for me to decide… many greetings Thomas
