Have any of you messed around with spheres for your enclosure ? I know Curt built some awhile back and did the whole enclosure as the cabinet. I found some foam balls at the hobby store and mounted a ND16FA in it . Just sitting down now to mess with it. I have just the one tweeter mounted now but may put a second one in the back just out of curiosity. Also curious , do any of you know if foam with dissolve if you tried to fiberglass it?
