Difficulty

BeoSound 1:
Slide front grille up to remove; undo the four TX10 screws holding the driver in place, and release each spade connector by pushing on its small spring retainer.
When installing the new driver, ensure the foam gasket is transferred, and the retainers locked on the connectors

BeoSound 3:
Remove the four TX10 screws on the base, and unplug the base module. Push in the tab holding the front grille, and slide down to remove it.

Unplug the keyboard, and release its retaining spring by inserting a screwdriver into the rectangular hole to the left of the keyboard cable. Remove gently.

Unscrew the two TX10 screws retaining the handle and holders. Pull the handle outwards on one side, and the holder will fall away.

Remove the 8 TX10 screws holding the internal cabinet, and slide it up and out of the extruded cabinet: the driver is removed with 4 TX10 screws, and two spring clips retain the spade connectors.
