These are easy to replace. Unfasten the mounting screws hold the front plate, remove the defective voice coil holder and replace with the new one! Replace the front plate, fasten the screws and you are as good as new.
This voice coil can be used for older Hales Transcendence & Thiel (CS2.2, CS3.6, etc) speakers that used a Vifa D26AG36-04. The original tweeter is a metal dome, and this is textile. It is on the same voice coil chassis and also 4 ohm impedance. The protective three pronged grill, may need to be clipped off, for best performance, and/or if there are dome clearance issues.
