So I bought from ebay these Samson Mediaone 5a Active Monitors. They look really nice ant the owner says that are practically new. No guarranty though. Took about a couple of days to notice that the left tweeter sounds a lot quieter and muddier than the right one. Did somebody else ran into this problem? The wiring is ok. Tried on differnt sources. Same problem if the input is on aux. Please help. Thank you!
