Logitech Z4 Desk Speaker Disassembly

Introdução

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.
