I have two RF62s; they are fairly new, only around 4 months old. I just moved them into my room, and they sounded great (both of them). But today I was tightening the cables, I finished tightening, and I noticed that the left speaker's low end was very not good sounding. I switched the right and left cables to see if it was a cable issue and it wasn't, it still only happened on the left. So I went to YouTube and found a Hz test. I figured out that my left speaker cut off ( as in I couldn't hear it anymore ) at 30ish Hz but my right speaker which had no issues cut off at 20ish Hz. I've looked through many forums and can't find anything about this other than maybe your speaker is blown but that doesn't make much sense to me cause I haven't been playing music loud enough to blow them out. Please help me!
