Can anyone shed any light on this? I recently added Mission 700s to my system, as rears. While testing them and playing about, I noticed that one is playing louder than the other. I have checked all connections etc and have found that which ever speaker is connected to the rear-right socket is louder. Is my Amp faulty and what can I do? The amp is still under garauntee but I don't fancy the hassle of having to return it to the shop.
