It’s good but is just slightly on the stiff side which will not be a problem if you are pushing larger than 3 inch drivers in a good sealed enclosure.

Works great. I wish it were round but it still looks and sounds amazing! The surround on this thing is crazy! it flexes like crazy when the bass drops! The 34;cone34; is made out of aluminium and holds up well.
