I contacted the Sound Organization (Proac dealer) who will find out if the original drivers are still available. I'd like to stay original but $800 is a lot of money for one driver! I read the same thing about the Proac drivers being "modified" Scan Speaks but I have my doubts. Guess I'll pull the driver out tomorrow and unsolder it to perform the 9V test and go from there. If the caps on the crossover are electrolytics then they should be replaced anyways, so maybe a crossover overhaul is in my future. Fortunately the PC board is large and simple and the components are discrete and easily removable; the most uncrowded crossover I have ever seen. The components are pretty good quality for a 25 yr old design, with large gauge iron core inductors. Can't tell what caps were used, they appear to be Proac branded. I have requested a schematic form Proac to assist in identifying nominal values.
Proac Response 3.8 stereo imaging is not centered
I picked up a pristine pair of Proac Response 3.8 speakers recently. They sound lovely, however the sound on one side seemed slightly weaker than the other side with the stereo image or soundstage offset to the louder side. This has never been an issue with my other speakers. Speaker cables are the same length. Switching the speaker wires at the amp output doesn't change the asymmetry. Switching the speakers from left to right and vice versa does change the asymmetry. So my conclusion is that the one speaker is slightly louder than the other? The individual speaker drivers are performing fine and the musical presentation is otherwise fine. Could the crossover components be the problem? Any other ideas to troubleshoot this?
