To get access to the tweeter, first you will have to pull out the kevlar mid-woofer beneath it . Then you can reach out to the rear of that tweeter mount. It is fixed by 2 lock-pin attachment (which holds the extended elliptical front logo plate) and mainly by a threaded nut. The rear conical chamber starts with a threaded section like a bolt which passes though a hole slot in the cabinet and is tightened by a nylon cylindrical nut to secure the tweeter from the rear.
This nut mainly hold the tweeter from the rear making the tweeter screw less flush mount from the front.
Reach out to the rear of the tweeter through the mid-woofer opening and grab this nut, Unwind it, loosen it up and open the nut & the tweeter will pop out from the front like browned bread out of a toaster.:licklips:
