My HT’s (Hertz HT25) were in the dashboard last summer and looked almost towards the sky. Now, when I wanted to put the HT’s in my new HT case, it was noticeable that the domes have “delles” When they were new, it was definitely not the case, then I am 100% sure. Due to the dents, it is now also clear that they have “delles” when they were new, that was definitely not the case, then I am 100% sure. Frequencies slightly distort……is not the world now, but the system finally cost money… David
