Hello,
I purchased a set of previously owned 340's across the front and htm-200's for rears. They are suppose to be 3 months old. I noticed that the 340's have these vertical or horizontal lines that go over the tweeter. I am assuming it is there to know the orientation of when you set them up but the pictures on the website don't have them. Mine also don't have the signature edition sticks on the back like pictures on the site. How do i know for sure if they are signature or not?
