Well I scratchbuilt some loud speakers for my Nam base camp but, as Slodder mentioned they look a little thick. I was wondering if some company makes something like this. Im really not sure what they actually look like though maybe some of you Nam guys could help. And also what would lights look like around a base camp. I want to make every thing acurate as possible.

Anybody have any ideas that might help me out.

I would try to use those, just get a piece of sandpaper and wrap it around a pencil end and use it to sand down the thickness.
I believe they are a nice shape and size, just a bit thick.
You may also try to use an old soda can or something similar (food container covers..) and then make a cone out of it, then snip off the pointed end.

Im glad you helped. I have tried to make them out of an aluminum cake pan but it is really tedious and couldnt get the same size. Maybe with more practice I can do better.
