at the end of disc one where they go to cut bottom of ships i hear a bad noise thought it was speaker,la scalas,but switched wires to right speaker still heard it.then i thought mid-drivers bad so got headphones out, no good headphones sound worse.does anyone else here this or is it something else causing the noise.the exact place on disc is chapter 31 where they are giving blood and a guy runs in and asks for help in the harbor then look out for bad sound.is it possible to check the midrange drivers with out hurting them take apart and look at the diaphram?thanks for help,ricktate
