Logitech Z4 Desk Speaker Disassembly

Introduction

disassembling the desk-speaker of the Logitech Z4 to access the driver and soldering points of the cable.

as you can see my speakers are quite old (around 2007 i belive) and the dissassembly did leave some more scratches and nicks, nothing that influenced the function of the speaker though.

the goal of the disassembly was to replace the cable that had a short close to the plug located at the sub-woofer.

What you need

Step 1 Unscrewing the speaker stand

removing the decorative front panel with a plastic pick (guitar picks work great). it is quite sturdy but the adhesive film on the back of it is strong, so go slow or heat it up with a hairdryer.

after opening the speaker fully you can see that the top and bottom membranes are not speakers, only decoration.
the middle one is connected with two wires matching the cinch connector on the cable.
the cable has a screw and some hot glue acting as a strain release for the cable.
