Hi, I have a set of Promedia 2.1 with the old sub, pictured below as an example:
They sounded fine, but one of the satellite speakers was cracked so I decided get a new set of satellites. After receiveing the new set, I hooked them up but noticed that sound was only coming out of one satellite. I flipped around the wiring to see what would happen, and this time the other satellite only had sound coming out of it. So it doesn't seem like it was the speaker that was the problem.
Reading similar issues on this board where the problem was a fuse or something in the sub/amp, I am wondering if that's the case with me considering my old satellites still work fine when hooked up to the same sub/amp.
