Once you have removed the outer blue casing,  four T-8 screws (15 mm long)  will be revealed on each corner.  After removing these screws, simply pull the top part of the speaker way from the body to get the the inner part of the speaker.

Once you have gotten to the internal parts of the speaker, there are seven wires connecting the speaker plate to the body of the speaker. Pinch the release tabs at the top of each of the four main wires to remove them.

Simply pull the thin wires on each side to remove them from their attachment points. Remove the final red and black wire by gently pulling it apart. This will ultimately  detach the speaker plate from the base.

Step 8 picture shows a small green pcb component, in my black model i nearly damaged this when sliding the white frame/main pcb out from the hard shell. The small component above is attached to the main board and to prevent damage i would suggest prising up/ apart the shell a few mm to get the pins out from the connector between them. Or risk bending the pins like i did or risk breaking the component. Great care needed to return these parts to their normal position when reassembling the unit. However the poc here shows there may have been a prior attemt to take it apart as i can see the green component has already been removed

Edit, its actually easier to remove the component first (prise it up from its adhesive backing very careful not to snap it as its a very thin peice of pcb here) before sliding out the white frame/main board, and it is far easier to ad last on the rebuild than trying to slide the main frame back in as lining up the pins is very difficult.
