I just recently converted a 15' audiobahn into a monster 10. This was just for fun cuz the old basket was cracked and the leads needed to be resolderd. i wasnt using it for anything so it was a budget build. so i bought a cheap 10" cone with rubber surround and the surround is maxing out from the 15" coil. so im looking for a good wide roll surround or erom style surround. already contacted sundown and fi, neither sell surrounds seperate.
as of now this is my best bet

as i stated this was just a random budget build with some parts that werent being used....so anything cheaper or better quality would be appreciated.
