Werkzeuge

Schritt 1

Remove the rubber layer beneath the device.
Look for the crater beneath the rubber layer and place your thumb on it. Hold down and lift off the cover with your other hand.
Remove the four 8.0 mm T8 Torx screws on the lid.
Remove the lid from the device.

Removing the rubber layer does not actually seem to be necessary.

Rubber base removal not necessary.

Screws for first few steps may be T10, but a quality T8 driver may also work

Schritt 2

Use a spudger to flip up the small flap on the ZIF connector.
Gently pull the ribbon cable out of the ZIF connector.
Lift the AMP Board gently while sliding the ribbon cable out through the center hole to reveal another set of wires underneath the board.

Amp board may have two T10 screws holding tweeter speaker, do not remove.

Schritt 3

Use a spudger to lift up one of the small flaps on only one side of the female connector.
Pull on the wire toward the lifted side until the male connector is disconnected.
Remove the AMP Board.

Schritt 4

Remove the four 30.0 mm T8 Torx screws in the corners.
Remove the large plastic piece on top of the subwoofer while threading the ribbon cable and male connector through the hole.

These screws are T10, not T8

Schritt 5

Remove the lid on top of the subwoofer.
Flip the device over and let the subwoofer fall into your hand.
The subwoofer is a strong magnet. Keep it away from any other electronics and unshielded wires.

I found the subwoofer was lightly adhered to the case, and didn’t “fall into” my hand until I very gently separated its edge with the point of a spudger.

Schritt 6

Remove the four 16.0 mm T8 Torx screws underneath the speaker.
Once you unscrew the four 16.0 mm T8 Torx screws, the remaining components of the device have no support. Take caution when flipping the device over to avoid damage to the remaining components.
Flip the device over while supporting the front panel side.
Remove the front panel cover by lifting it.

The front panel cover doesn’t seem to be keyed, so if you find yourself wondering, the “+” button should be positioned to be closest to the power connector (the long plastic strip the slightly moves out of the rest of the cylindrical chassis.
