I was running my fingernail across the gold speaker cover strip on the back. I noticed in the middle that it pushes in quite a bit. It's like that part is not properly secured to the backplate. Could someone else attempt this for me. I want to know if it's how it was constructed, or if it's just my unit. Just run your fingernail with LIGHT pressure across the speaker cover. See if it pushes in in the middle. Thanks.
