Hey, this was my project from few years ago when I was getting into 3D modeling. I was looking for a project to learn basics. I redesigned speakers for an old and broken home cinama studio. The goal wasnt to make it work as before, the main goal was it to make it look more pleasent for eyes.
Image how they looked before ( not my actual picture, mine had broken and cracked frames with color drips all over the speakers )

The whole design is made to be assambled as easy as possible. All you need is 4 screws for each speaker ( I used M3x8mm self tapping screws), the rest of the parts should fit together without any other hardware.
I used a piece of fabric between the protection frame and the front frame.
The author marked this model as their own original creation.
