A friend of mine had a pair of the xs650 tower speakers offered at monster tower, which were in perfect shape and worked great. I sold them to a guy on ebay, and the speakers/amp included were tested to ensure they were in good working order. The buyer received these today and told me one speaker was only getting 10% of the volume compared to the other, testing on the same channel. I told him to open the speaker up to check connections, and he said the magnet fell off, which he re-attached...which fixed the problem a bit. Does this sound legit or does it sound like something else is going on?
