Use a Phillips #1 screwdriver to remove the four 1.3 cm screws holding down each driver.
Gently pull the plastic plate towards the antenna cable.
There is a small antenna cable that is easy to rip off the solder joint, so lift carefully.
There are 8 screws on the long side of the housing, but there is no driver behind it, so you don't need to remove them.

Шаг 10

Pry the speakers from the housing with a spudger.
The speakers are connected to a spring-loaded pin connector which is attached to the black plastic using industrial hot glue, so while you can heat the glue to remove it, the plastic may melt and/or deform, so we wouldn't recommend it.
