TAKING APART THE CX50
STEP ONE

NOTE
Evaluate the state of the speaker drivers and make
sure they are in good condition. If the speaker
foams are damaged a repair is needed.
You can either:
a) refoam yourself (refoaming kits and instructions
are available here: (link to come))
b) buy new drivers compatiable with the original
(link to come)
c) get them repaired by a professional

CREATING A NEW POWER CONNECTION
STEP TWO

Remove the original plastic speaker
connector with a saw. Make sure to cut
through the wider end, upon which you will
be later placing the 3D printed puck.
Screw the power plug into the 3D printed
puck.

Apply glue to the 3D printed holder.
Make sure to cover all the inner walls with a
vast amount of glue.
Place the parts upon the opening you just
created. Make sure they fit in as tightly as
