Need help : Jm Lab mini utopian tweeter repair problem

Options
hi guys

My friend have this speakers' tweeter fault and need repair, but we found no way to remove the back though we removed all screw, and tried air sucker.
Would anyone kind enough giving any input?

Thank you so much in advance.

And please pardon me for my terrible English.

    Remove all the screws

    Take an object that is rigid and stick it thru the front slot beneath the tweeter and line it up with the back panel.

    Tap gently with a hammer while holding the back panel with your hands

    The tweeter is then held on with threaded rod and washers, you will see.

    Take your time

    This is also a very difficult repair to perform to simply redo the foam. Focal does sell a replacement diaphragm but it is not coated

    Side note, the crossover is on that panel so try not to tap against any of those parts

    Thank you for your prompt reply.

    There is something I don't understand, though.

    "Tap gently with a hammer ", where exactly should I tab? the front panel, or the object or the back?, thanks again

    Above and below the tweeter is the port to the speaker

    Stick a long object that will reach to the back of the speaker like a piece of wood or metal

    Find the back panel with the long piece of material

    Tap it with a hammer

    It will pop off
