The following guide is based on information from the now defunct tam.axon.net forums for the 20th Anniversary Macintosh. Special thanks to Philippe for providing the information.
The TAM subwoofer is held together by the ‘cap’ on the top and screws below. Removing the screws at the bottom is the easy part. The ‘cap’ has to be gently pried out or the ‘legs’ holding it down will crack easily. You will need to find a suitable item to lift the ‘cap like a wooden spatula or screw drivers wrapped with insulation tape as I have done.
1. Flip the subwoofer upside down and rest it on the table. Remove the rubber strips by carefully peeling it out. It is held by double sided tape and should be easily removed. Be careful not to pull too fast for the rubber may have hardened over the years and snap.
2. The screws will now be visible. Remove the screws and sit the subwoofer the right side up.
3. Here comes the tricky part to remove the ‘cap’. It has to be lifted up evenly or the ‘legs’ holding it will break. I have used four screw drivers to pry it loose. Place a soft cloth to cushion the screw driver or it will leave marks on the rubber part of the subwoofer. Electrical insulation tape is wrapped around the screw driver tip to prevent scratching the ‘cap’.
4. With the ‘cap’ removed, the rubber piece can now be pulled off. It is held by double sided tape and should come off with a little force. Remove the screws that are now visible.
5. A helping hand may be required to hold the base of the subwoofer while you lift the case off.
Now that the case of the subwoofer has been removed, follow our next post to solve the buzzing/ humming issue.
