Do you have any pictures of the back?
Not yet but I'll post some soon.. But there's nothing special about mounting that tweeter . You just need to make adapter to adapt Tweeters 34 mm throat to woofer's throat. And glue that in there..
Some testing done and versoon 4 of x over done.. Seems that woofer and midrange work just fine with passive X over, but Tweeters will be driven with another amp because of their low sensitivity.
