Problem With Roland MA-8BK

[Abbott]

The other day I noticed that when I was listening to my band's mix through the rolands, the majority of the sound was coming out from the right speaker. At first, I thought it was panning, but no. I panned the guitar all the way to the left and couldn't hear it. I changed the cables, tried it on headphones, concluded that it was the monitors. Now, what could be wrong? The only way to hear what sounds like a balanced mix is to put the volume all the way up, but that isn't going to work much longer as I start using the monitors for more and more things. Did I blow them out or something? Thanks for any help.

Are you saying you get no sound from that speaker at all? Did you try switching the speakers but not the cables? What are the monitors? Do they have bare wire connectors on the back? If so make sure you have them wired correctly. If the polarity is reversed it will sound very weak and thin.
