Hi guys~ I recently picked up a pair of used PSB image 2b speakers. I have been running B&O RL 140 speakers that sound great on a Kyocera r861. I saw the 2b's at a reasonable price and picked them up. The seller allows returns. Here is the issue~ The sound of the 2b's is incredibly muffled. Non existent mids or highs. They are connected to the kyocera. I have never actually used banana plugs before which I believe I needed for the 2b's and so it is possible I did not set up the plugs correctly~ I noticed that the plugs them selves do not fit all the way into the speakers. They are "knob" plugs i believe? I pushed a bit of speaker wire through them, fanned them out into a mushroom and screwed the top on. What do you guys think? Thank you for your help.
