Magnus,
Thanks for the information. Hope the replacement 3.5's have the problem resolved. I will contact my dealer and see if he will do the same for me. As I live in the U.S. where the customer services the company instead of the other way around, I will probably have to replace the speakers myself. I have the complete surround system and two MTS w/ sub for a dedicated room. Every 3.5" driver has a problem now except one. Listening to a pair of Audioengine 2's instead of surround right now, and bought a pair of Dunlavy's for the dedicated room. Perhaps the New Year will find working Preludes again as they are excellent sounding speakers.
