The Speaker

This is a fully customizable speaker powered by Blenders geometry nodes. You can create a quite big variety of speaker (at least the normal box kind of speaker) and that also includes a guitar amp speaker if you're into that.

The shader for it includes some CC0 textures as well, but seeing that the variety in shader is also quite huge it will not compile in Eevee at all, not sure exactly what it depends on but on my RTX 3090 I only get a fully pink speaker whenever I try. But for Cycles it do render just beautifully :)

To use it you can either append theSpeaker object or node group from the .blend file, or just open the file itself.
