Ron, I took a few more pics of the inserts and of the back.Essentially all they are is soft white foam about 2" thick and then he cuts them to dims.I personally like them (19's) better with the foams then without.Anything you can do to deaden the ring of Metal horns the better.But for $50 I'm happy with them I was digging for the transaction I paid $45 for the foams and $8.95 shipping & Insurance.But the foams have since gone up since then to $55 + Ship Regards ~ JOHN
