I have a older pair of Dynaudio md100 tweets, as you can see from the pics the backs were soldered (poorly by me, what can I say, I suck at it) They work perfect. If you can solder then you are good to go. The front is pretty good but not perfect. I would say 7.5-10. No mounting hardware is included but it would be really simple to get your own bolt and strapping to make your own. I have had them for years just hanging around and not using them so I am just going to sell them. $90b/o shipped to anywhere in the lower 48.
