Whizzer cone removal

I would leave it alone.....no going back if you cut it off or damage the cone while trying.   

Leave 'em alone!

I have big experience with removing whizzer cone, if you leave WC.,
is impossible to get good result with using Tweeter, All my model
Bache Audio i cut WC  in Tang Bang driver, i tell you based on long
time listening and measuring using RTA system. Dont hesitate, just
get sharp hobby knife and go ahead. The WC-is primitive tweeter
and cannot compare with  update High Quality Tweeter or sypertweeters.
I think WC came from   old professional audio using in Cinemas and came to Home Hi end for folk who liked vintage
I am wondering why some famous  brands using WC
