This is a replacement voice coil for the Scan Speak, D2905/9700 tweeter.
Yhey are easily replaced by first removing the face plate screws and exposing the dome. Remove the plastic trim ring and gasket. Next, de solder the lead wire from the terminals and then pry out the bad coil / dome assembly. Replace with the new dome/coil assebly, re solder, and replace the plastic trim ring and gasket before re attaching the front plate.
