Hi there, I have a pair of M audio BX5 speakers, one of them works fine, on the other hand, the other one sounds kindda funny. Both of the twitter and the 5-inch cone on it work, the main thing that's noticeable the most is the volume is a lot lower than the other one. I have switched the cables and the outputs back and forth a lot, but it didn't work. I use to be able to fix it just by turning the volume nob to the loudest and the volume will come back to normal in a bit, but now, this doesn't work anymore. I tried to match the level of the other speaker to this one to see if it's only the volume difference, but it turned out there are frequencies that are missing as well. Would you tell me what it is? Thank you so much. Wen

Little goes wrong with a speaker unless it has either been overloaded or subject to damp, extreme dust or has sustained physical damage from some sort of accident.
A rough test is to move the speaker cone gently through most of it's travel using an even pressure simultaneously on various places around the cone, I use my fingers.
It should move smoothly without any resistance and most importantly it should be completely silent through the largest or smallest movements.
If it sounds scratchy, the speech coil is either off-centre or it has suffered damp or dust and dirt has ingressed into the air gap or the chassis has become distorted.
If it is silent and electrically sound it should produce normal volume.
There was a time when loudspeaker repair, overhaul or adjustment was routine but these days it isn't economic except for the highest quality and replacement is best.
After gaining access to the interior wiring of the speaker cabinet I suggest further testing it by wiring it direct and leaving out the crossover if it has one.
