Right channel sounds fuzzy and doesn't seem to have the same volume as the left channel. Basically I noticed this issue when the vocals moved to the left one day and stayed there. I went up to the right channel and sure enough, I could hear it but nowhere near as loud as the left and the highs coming from the tweeter were distorted and fuzzy.
I've since hooked up an old Jolida 1501 and the speakers sound fine.
