I just received rullit aero 9 and a power supply from Vietnam. I sat them on my office desk and listened to them. Ok not deep bass but not bad but have a kind of fluffing noise. So yesterday the weather was kind and I took them to my listening room in the garden and fitted them into my quarter wave boxes. I have also rullit silver lab 8 and aero 8 both sound great. But these aero 9 sound distorted something awful. Any thoughts on this appreciated. The seller sent me a video of them in his room and sound ok and I don’t doubt they were ok when they left him. Could something happen in transit to cause this issue.
Is the voice coil moving freely or does it rub?
Is the power supply the right fit for the field coil and the current draw makes sense? Have you checked that? What is the nominal current for the field coil?
