Step 5  ¶ 

This is the hardest part of the teardown. Take a shot. Meditate. Prepare. Carefully heat the glue along the plastic frame of the speaker. It will be difficult to heat the glue without deforming the plastic frame, as gratuitous amounts of glue were used and the frame wilts at the mere suggestion of heat. For those of you who can shoot fine lasers from your eyes, this would be a fine time to utilize that skill. Pull the speaker away. If you’re patient, you might be able to pull out the speaker without damaging the frame too badly. If patience eludes you, as soon as you apply heat, get something to use as a wedge, start prying, and pray for the best.
