  • You should have removed a total of 7 machine screws and 2 washers.

  • The reason for removing the two screws with the two washers first (or replacing them last when reassembling) is that their holes are actually slots. They are designed as slots to accommodate slop in the assembly, and if unscrewed out of order, you may have difficulty while removing - or possibly even damage - the other five screws.

Inside the metal electronics box housing is a white clip attached to a small PCB; remove this. The white clip in this image has been glued, indicating that the manufacturer may not expect  the end user to remove this clip; it is difficult to proceed with the disassembling without doing so, however, because the rest of the speaker does not provide a sufficient surface on which to work. Snake the clip head through the hole in the metal electronics box casing.

In Step 3 there are 2 more screws, along the side of the 'electronics box’.

The washer and nut securing the 1/4” socket also need to be removed.
