Voice Of The Moon - Vuoluset

I was sent some information about an interesting speaker company based in Finland making speakers out of stone called vuoluset. They make there speakers out of stone. Unfortunately they don't have an english page yet.

But on the moon without atmosphere is there a sound? I think something was lost in translation. Very interesting monitors. I wonder how much it would weigh to have a very large horn made of stone.....

Very interesting. vuoluset.
